3D City Model – Rendering Services and 3D Modeling

Lets say that your pitch was successful and now your clients want your 3D animation in a futuristic 3d model city scene. However, you are an expert in animation but not in 3d modeling and 3D city models are known to take several weeks to do! For example the 3D animation you used for the demo took you 2 weeks and they now want a more complicated one in just a week...HALF THE TIME AND MORE TO DO.
You could customize a stock 3d city model scene to look futuristic or outsource it. This project has an aggressive deadline and you are not very skilled in customizing 3d city models quickly...by having someone else do it for you it will allow you to focus on the animation. Sound familiar? Outsourcing 3d modeling and rendering or doing it in-house is a common dilemma 3D model artists and animation studios face, especially when rushing to get 3d projects done.
When it is a good time to outsource your 3d modeling? A rule of thumb from one of our clients is that "If someone can make it in half the time I can...then its time to hand it off. My time is just too valuable."
Typically, clients outsource 3d modeling and rendering when the 3d model, such as a 3d city scene, can be done or customized much more efficiently by custom 3D services such as Flat Pyramid Custom 3D. Such as, creating a 3D New York City Downtown model Scene in a 3D file format like max, obj, maya or 3ds. What could take weeks to do can take expert 3d modelers that specialize in 3d cities just days. So you get less frustration, quicker turn around, and higher quality results, which are worth spending money on.
Below are tips to help you know when outsourcing can work for you:
- You come across something that you don't do very well that is not part of your core competency. Also it will take time to learn it and become efficient at it.
- You have too many 3D projects stuck in the pipeline and budget constraints prevent you from taking on more 3d artists on staff.
- 3D modeling projects go in a cycle and so to avoid downsizing in the future you want to ensure that you only need the appropriate people at any one time.
- The 3D project is a one-time project.
- favorably when bidding for 3D model projects such as 3D city models.
- It is more productive and profitable for you to let expert custom 3D services handle it.
Your profits can be increased significantly by saving on labor cost due to outsourcing. Outsourcing experts agree that having someone else do the areas that are not your expertise enables you to do more and you can leverage lower labor costs and increase your profit.
Realize you can't do it all and you must other options and ways to increase your 3d development cycle and get your 3d projects to your clients and or customers a lot quicker and cheaper than your competitors - or face losing clients.
When you have decided that its best for you to outsource, consider using the expertise of 3D model artists with a wide range of experience in custom 3D modeling and Rendering including 3D city models.

The Art Of Building Model Houses An Overview

Do you remember how fascinated you were, as a child, about building houses or blocks with toy bricks and Lego? Personally, I enjoyed this so much that I was even using my playing cards to build small houses for my dolls. As we grow and become more handy, wise and skillful, we can refine this passion for building houses. Around the world, there are thousands of people who share a passion for building model houses that are basically some miniature houses very similar to the real ones.
Building this kind of houses is a sub-activity of the constructions and architecture fields. Many constructor engineers and architects have the ability and know-how of creating houses at smaller level, but they prefer to outsource it to people who specialized in this field or simply started doing it as a hobby and then ended up by making a living out of it. And there are people who simply stick to building small-sized houses during free time because they enjoy it a lot and find it a very fulfilling activity.
In either case, the process is very pleasant because it involves creativity and perseverance to reach mastership. All you need when starting your journey through building model houses (a journey that for most people lasts a lifetime) is, besides patience and imagination, the material your house will be made of, plus basic cutting, measuring and sticking tools like knives, scissors, paper-cutters, scales and glue. The tools you'll need can usually be found in hobby supplies stores, being available most frequently for 1:16 or 1:8 scales.
To come to create a masterpiece, you have to go through several stages. The first step is to understand the house's blueprint. Then, you have to begin by creating the floor, then, separately, the parts of the house and finally it comes the assemblage.
The chosen material is very important. For beginners, it is recommended that they start with using paper and once they become more skillful, cardboard, to build their model houses. The main advantage of paper and cardboard is the relatively low costs, while their disadvantage is their poor resistance to pressure or rough handling. Beginners can also go for a kit comprising all the items needed to start building. In this case, all they need to do is put together the pieces, according to the blueprint provided. Using a kit is limitative in terms of creativity, but it can be helpful until getting a basic understanding of how things should be done.
Students and people from the branch prefer to use foam as it is easy to handle and can create impressive effects, while wood is a material that becomes suitable when we are already pretty experienced in building model houses. It can be used as craft sticks but also as rough wood, which involves a high degree of skillfulness to handle and turn it into a small piece of art.
When we come to master the art of building model houses, we can also go for special houses styles like Japanese houses that are mainly made of wood, Victorian, Tudor or Georgian houses. They require a lot of imagination and work, but the result is equally satisfying. Along with skillfulness will come the desire to start creating the house's surrounding area including trees, roads, yard, rivers and even focus on decorating the interior of the house. At a proficiency level, we will want and even go for building entire model villages, towns, farms or whatever our imagination and passion lead us to.

Biztalk Development – What is The Publish-subscribe Model?

Here is some basic information for Microsoft Biztalk Server, I have read a lot of but I decide to cleare some basic questions that need to be answers and many peoples waiting for them, The Microsoft BizTalk Server is basically a messaging system that is based on a model called Publish-Subscribe. This Publish-Subscribe model being an asynchronous programming technique allows information sharing between publishers (entities that send information) and subscribers (entities that receive information) smoothly.The Publish-Subscribe model gives two biggest advantages - scalability and flexibility.
The Publish-Subscribe model works as if one is addressing an audience through a speech so that the speaker is the publisher and the people in the audience are subscribers. The number of people in the audience is irrelevant; the only thing relevant is the way of information communication. The way in which the information is projected to the subscribers forms the scalability "" reaching a larger number of people through a louder way.
For the speech (content) of the publisher too the number of people is unaccounted. In fact, during the speech existing listeners can leave and newer subscribers can enter at their will without affecting the publisher or the speech. Hence the publisher is not coupled with any individual subscribers and the number of subscribers too is anonymous for the publisher. This defines the flexibility of the BizTalk Server system.
BizTalk Server development allows the system to handle messages in the same way, i.e. the BizTalk Server (the speaker) publishes messages to a common area (the audience), and processes (the people) in that common area that are interested in consuming the published messages subscribe to them (orchestrations, receive or send ports, or directly bound ports).
Though, the Publish-Subscribe model isn"t meant to work for all subscribers receiving all messages. The model has a filter of interests that passes the messages related to the subject of which the subscribers have subscribed to. In BizTalk development there are two general filters "" one to filter out messages based on their topics, and the other filters the messages based on their content.
So we are done with the Subscribers in the BizTalk development architecture and now for the Publisher"s part. One can publish messages in BizTalk through:
1> Sending a message to a receive port
2> Calling an orchestration from another orchestration
3> Creating a direct bound port (more about this in a future article)
4> Publishing messages for which there are no subscribers (known as routing failures)
BizTalk provides a robust platform for business processing as it can overcome any system failures including hardware and software. The SQL Server is majorly accounted for this robustness as it is BizTalk's message and configuration store. The SQL Server also stores and routes messages for BizTalk in addition to publishing and subscribing to them. MessageBox is the logical name for the common location and BizTalk SQL Server database where publications and subscriptions take place in the BizTalk Server. Other than the fact that it exists and that its implementation is an integral part of BizTalk development there"s nothing significant of the MessageBox for a developer.
Lastly, a message's type is defined by its XML representation, and is treated just like C# treats its own types. And during message passing too one cannot pass a string to a function that expects an integer, lest the compiler generates an error.

Some Basic Theories on Open System Interconnection Reference

The Open System Interconnection Reference Model or OSI Reference Model or OSI Model is basically a conceptual description for layered communications and computer network protocol design. It was created as part of the Open Systems Interconnection or OSI initiative. In its most fundamental form, it segments network architecture into seven distinct layers: the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection of theoretically similar functions that provide services to the layer directly above it and gets service from the layer beneath it. On each single layer an instance provides services to the instances at the layer above and requests service from the layer beneath. An example of this relates to a layer that provides error-free communications across a network which then provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that comprise the contents of the path.

Work on a layered model of network architecture commenced in the year 1977. Simultaneously the International Organization for Standardization or ISO started to develop its OSI framework architecture. OSI has two major parts: an abstract model of networking, called the Basic Reference Model or seven-layer model and a set of specific protocols. It is important to note that the standard documents that describe the OSI model can be freely downloaded from the ITU-T as the X.200-series of recommendations. A number of the protocol specifications can also be accessed as part of the ITU-T X series. The equivalent ISO and ISO/IEC standards for the OSI model are available from ISO, however not all of these are available free.

Every area of the OSI design evolved from experiences with the CYCLADES network, which also had a large influence on the design of the internet. The latest design has been meticulously documented in ISO 7498 and several of its addenda. In this latest model, a networking system is segmented into layers. Within each layer, one or more entities proves its functionality. Each entity will interact directly only with the layer just below it, and enables facilities for use by the layer above it. Protocols will allow an entity in one host to interact with a corresponding entity at the same layer in another host. Service definitions ideally describe the functionality provided to an (N)-layer by an (N-1) layer, where N is one of the seven layers of protocols operating in the local host.

Neither the OSI Reference Model nor OSI protocols designate any programming interfaces, other than a purposely abstract service specifications. Protocol specifications precisely define the interfaces between multiple computers, but the software interfaces within computers are implementation-specific.

Take for example, Microsoft Windows' Winsock, and Unix's Berkeley sockets and System V Transport Layer Interface, are interfaces between applications (Layer 5 and above) and the transport (Layer 4). NDIS and ODI are interfaces between the media in Layer 2 and the network protocol in Layer 3. Interface standards, with the exception of the Physical Layer to media, are estimated implementations of OSI Service Specifications.

Free to Air Satellite

FTA is in certain circumstances delivered by satellite television, but in many different locations of the world free-to-air television channels are actually broadcast unencrypted on UHF or VHF bands. Despite the fact that these channels are described as free, in some cases the viewer may have to pay for them. Some of these channels are paid directly by payment of a licence fee, for example as seen with the BBC or by voluntary donation for example PBS. Others indirectly pay by paying for consumer products and services where a portion of the cost is used for television advertising and sponsorship.
Free-to-air is typically used for international broadcasting, making it in some way a video equivalent of shortwave radio. Most authorized FTA retailers will list free to air channel guides and content available in North America for free to air use.

There are many competing systems presently in use. Many of the older channels used C-band satellite dishes of several feet in diameter to receive signals which were at first analogue microwaves, and then digital microwave using the 3.9-4.2 GHz band. Currently, in the 11.7-12.2 GHz Ku band permits the use of under one-meter dishes chiefly with the DVB-S standard. Hence FTA can now be used from apartment balconies.

The most prevalent North American sources for free-to-air DVB satellite television includes:


NASA TV Multi-channel(NASA HD, NASA Public, NASA Media, NASA Education) Broadcast on AMC 6 (72W)
Retro Television Network on AMC 9 (83W)
TVU Music channel and This TV on AMC 3 (87W)
ABC News Now on Galaxy 28 (89W)
Eternal Word Television Network on Galaxy 17 (91W)
My Family TV on Galaxy 3C (95W).
AMGTV and BYU Television on Galaxy 19 (97W)
English and foreign language broadcasters RT (TV network), MHz Worldview, Ebru TV, IRINN, Al Jazeera English and more up-linked by GlobeCast World TV on Galaxy 25 (97W)
Christian broadcasters The Word Network, Emmanuel TV, Daystar Television Network, JCTV, Trinity Broadcasting Network, The Church Channel, God's Learning Channel and more promoted by Glorystar & Spiritcast Satellite Systems TV on Galaxy 25 (97W)
Pentagon Channel on AMC 1 (103W)
Jewish Life Television, ResearchChannel, and University of Washington TV on Galaxy 18 (123W)
Montana Public Broadcasting Service on AMC 21 (125W)
Louisiana Connection Network on Galaxy 13 (127W)
White Springs Television on Galaxy 27 (129W)
Classic Arts Showcase on Galaxy 15 (133W)
Football, Basketball, Baseball, Soccer, and Hockey wildfeeds on various satellites

Many of these signals are carried by United States satellites. There is a small number of or no free Canadian DVB-S content available to users of medium-size dishes as much of the available Ku-band satellite bandwidth is used by pay-TV operators Shaw Direct and Bell TV, however the large style dish of over 3 feet/90cm does have a few extra choices. FTA signals may be dispersed across multiple satellites needing a motor or multiple LNBs to receive everything.


Free-to-air satellite TV is a feasible addition to any home video system, not only because of the specialized content it makes available but also for use in areas where terrestrial ATSC over-the-air reception is not at acceptable levels and additional channels are needed.

Tips and Techniques About Green Architecture

As more and more people become interested in the effect they are having on our environment, the ability to design and construct buildings that are energy efficient and environmentally friendly is becoming more important. This area of design is called green architecture and is a growing trend amongst those wanting to live in harmony with their environment and those wishing to conserve traditional energy resources.
Green architecture aims to work in harmony with the natural features that surround the location of the project, to use construction materials that can be easily grown or that have been recycled and to maximise the energy efficiency of the building. This has benefits for both the environment and for the occupants of the building.

Green architecture should use the natural ecology of the planet as a macro model and green architects should always keep the environment in mind when designing. Listening to a client and transforming their needs into a workable, energy efficient and environmentally friendly design is a skill and one that you should ensure your choice of green architect has.

A building designed using green architecture will reduce energy bills, use less water and will reduce the amount of waste being added to landfill sites. There are a variety of ways through which these savings are achieved.

One of the best known methods of reducing energy bills is to have solar panels installed. There are many benefits to using solar panels ranging from low maintenance and versatility to it being non-polluting and a renewable energy source. After the initial installation, there are relatively few ongoing costs. No moving parts mean low maintenance and the heat and light from the sun is free!
Another method used in construction of green architecture is thermal mass. Insulated Concrete Forms (ICFs) produce a framework when locked together much like Lego bricks. This framework forms a permanent and integral part of the building and is pumped full of concrete that has been composed and cured to reduce its thermal conductivity. This produces the thermal mass required to reduce the effects of outside temperature fluctuations on the ambient temperature inside the building thus reducing energy bills.

The use of recycled materials is becoming increasingly popular, as is the use of green materials. Recycled materials include glass, plastic and tyres while green materials include wood, stone and earth. Using these recycled resources helps to reduce the waste being sent to landfill sites and the use of the green, more natural resources helps our buildings blend more harmoniously with their environs.

These techniques are just some of the ways that green architecture is helping to make our buildings much more sustainable and environmentally friendly. For example water, mud, rammed earth and logs can all be utilised to provide thermal mass to a building instead of ICFs. Which one is right for your project should be determined by the environment around the location of the building and the immediate ecology of the area. Discussions with your green architect will help you decide how to proceed.

Other techniques involved with green architecture are maybe not so well known generally but your green architect should mention them as they all help to add to the energy efficiency of a project, for example:
Using locally sourced materials reduces the cost and use of fuel for transportation and if trees are felled to make room for your project then this wood could be put to good use in the construction.
Recycling grey water (waste water from baths, showers and wash hand basins) can be captured, stored and treated to a standard suitable for WC flushing.
Rainwater harvesting can be as simple as a water butt under a downpipe or a more complex over or underground tank depending on your use for the water which can be anything from watering your garden or cleaning your car to flushing your toilet or having a shower.
Small scale wind turbines can be used to generate energy to charge small batteries with applications such as lighting and electric pumps.

Many opportunities exist for all of us to start living in a way that is more in harmony with our surroundings. Whether you want to light your garden using solar power, generate wind energy to light your caravan or build a home from scratch that is environmentally friendly, energy efficient and at one with nature we can all add to the conservation of our planet.
Green architecture is the way to release ourselves from the grip of fossil fuels into the hands of renewable energy, green architecture is the future of us and of this planet.

N-tier Client-server Architecture- An Overview

N-tier architecture is an application structure wherein the work for the servers (service- providers) and clients (service requesters) are separated to ease developers in developing web applications. The structure includes a number of levels arranged one upon another and each level is allocated for distinct set of task. Also known as multi-tier architecture, this client-server architecture includes separate sections for presentation, application processing and data management processes.
It is often seen that both clients and servers undergo communication over a common computer network but by using separate hardware. The computing system of the service providers (server) host a number of programs to be shared with the clients. On the contrary, a client may not share any of its personal resources with the server machine and instead, may send incoming request for services from the server. Here lies the use of N-tier client-server architecture which lays down a model for web developers to create customized web applications as per the specific business requirements.
A major benefit of using N-tier architecture is that web developers can easily separate the applications into multiple tiers and can modify them rather than rewriting the entire application. Furthermore, the applications are loosely connected with each other and changes made in one application do not hamper performance of others.
Generally, web application developers use 3-tier application, which includes a programming tier, a logic tier and a data tier. The user interface programming tier translates task to help user easily understand the information related to services. This topmost level of the application structure interacts with other tiers by providing results to all other tiers in the computing network. The logic tier controls the functioning of the application by processing commands, evaluating and calculating specific data. The information from programming layer is later stored in the database servers of the data tier. The stored information is then transferred back to the logic tier for further processing and ultimately to the users computer system.
Web applications meant for e-commerce websites are popular examples of N-tier client-server architecture. If you want to have web-application created out of using N-tier application program, then you can seek assistance from software development companies. There are a few software development companies which have skilled engineers to provide flawless combination of various layers for N-tier client-server architecture. You can also hire some offshore web developers who are experienced in handling database including Oracle, SQL Server, MySQL and MS Access.
So, spare out some time to find reliable software development companies and hire web developers to get web applications created out of N-tier client-server architecture.

The computing system of the service providers (server) host a number of programs to be shared with the clients. On the contrary, a client may not share any of its personal resources with the server machine and instead, may send incoming request for services from the server. Here lies the use of N-tier client-server architecture which lays down a model for web developers to create customized web applications as per the specific business requirements.
