The term “drafting services” encompasses several activities. Examples are 2D drafting, 3D drafting and 3D visualization. The subject of this article is 3D visualization, and some of the on-the-ground realities associated with it.
3D visualization is the creation of a computer-generated drawing which is remarkably lifelike, so lifelike that the viewer must wonder, “Is that a computer-generated drawing or a photograph?”
The process of 3D visualization creation can be broadly divided into two steps: model creation and rendering.
Model Creation
This entails creation in the computer’s memory of a 3D object that looks exactly like the target, real-world object. The 3D visualization expert uses one or more photographs of the object or perhaps 2D drawings of it as input information. Although the 3D visualization expert will inevitably have specialized drafting skills and spatial conceptualization ability of a high order, he can take hours, days or months to create the object depending on how much detail is in it.
The completed model typically looks totally gray; also, there is no light falling on it and it therefore generates no shadows. The surface colors, lighting and shadows are created in the second step, i.e. rendering.
Rendering
During this stage the 3D visualization expert specifies to the computer the surface finish of every part of the object as well as the intensity, color and position of the various lights that shine on the object. Examples of surface finishes (also called ‘textures’) would be “metallic red”, ‘beige linen” and “green moss”. Examples of lights would be “daylight”, “spotlight” and “directional light”.
Once the computer has texture and lighting information, it pastes the specified surface finishes onto the appropriate surfaces and places lights of the specified intensity and color at the positions decided by the 3D visualization expert. It then draws light rays from every light source to its final destination. A ray could travel from a spotlight to an object, then bounce off the object at the angle of reflection, hit another object, be reflected onto a third object, etc., losing intensity as it progresses along the path. When millions of light rays are drawn in this way, the result is a very realistic illumination of the object and its surrounds, complete with shadows and reflections (this is known as a ‘photorealistic rendering’).
As one might imagine, the rendering process consumes enormous computing resources due to the very large number of light rays that have to be drawn. To render one scene consisting of a house surrounded by vegetation can often10 hours or more on the fastest desktop. If animation has to be created, which usually calls for 24 images per second, a 10-second animation would comprise 240 images, and the time taken to render these images on the computer would be 240 x 10 = 2400 hours = 100 days! Most probably by this time the client who wanted the animation would have lost faith in the 3D visualization expert and moved on to someone else who could do the job faster.
Because of the long times taken for rendering, there was at one point a to drastically speed up the process. Software engineers found, in due course, a way of sharing the task of rendering between multiple computers. This concept did not imply that when 240 frames were required, each computer worked on a separate group of frames. It implied that even a single frame was worked on by the group of computers with a result that the rendering time for a single frame was less by orders of magnitude.
A group of computers that work together for rendering is known as a ‘render farm’.
It was often not feasible for drafting services to set up a render farm in their own office using five, 10 or more desktops. This constituted another need, one for rendering systems at low cost; and just as in the previous instance there was soon a solution: the online render farm.
Online Render Farms
As you may have guessed, an online render farm is a render farm that can be accessed on a chargeable basis from any Internet terminal. Because it is online it can be used by more people than an offline farm, making it all the more commercially viable than an offline farm.
But experience shows that it is not always a good 3D visualization solution. For the one part, it’s not as cheap as one would like it to be (experience leads one to believe it costs $1.50 per second of CPU time).
Another fact is that although most online rendering render farms have online speed calculators which tell you that what takes your desktop 10 hours takes them only minutes, when you actually send them something to render you can be in for a jolt. You have to take your place in a processing queue and wait your turn, and it can often take more than one and a half hours before your turn comes! Whither the time savings?
Conclusion
The motto of the story is not to think that an online render farm will solve all your computing resource problems as concerns 3D visualization. Apparently all the farms are overbooked at this time, and it will probably be some months before enough new farms come into being to reduce the average waiting time to a few minutes.
The ideal solution would be to either have a special arrangement with an online rendering render farm for a maximum waiting time guarantee, or to render jobs on your own render farm (which of course might be subject to investment constraints, which will limit the amount of equipment and therefore the complexity of the 3-D visualization jobs you can render).
The important thing is to embrace the render farm concept and customize a solution that works for you based on the above suggestions. Be assured that such a solution is indeed out there!

Architectural rendering basically means preparing and presenting a proposed design of a building for the approval of the person who wants to construct it. It may be a commercial or a residential unit. Formerly, the architects and designers would just draw bare outline sketches of the various parts of the building giving their dimensions and how each room/unit of the building was to be juxtaposed with the other. It was almost impossible for you to correlate the built up unit with what you had actually dreamed of.
With the advent of computer aided design (CAD) and the related multimedia based architectural technologies, the process of presenting how the prospective building will actually appear after it is built, has undergone a sea change. Now as the owner of a building, you can virtually see and feel your dream-house at the stage of its conceptualization and planning long before it comes up. You can select a view from a wide spectrum of various designs of the building and colors of paints. You can also suggest changes as per your preferences.
In the past, it was almost impossible to communicate the subtleties of the designs and the shades of colors to the architect as you wanted them. Now, with the advancement of the presentation technologies, especially architectural rendering, it has now become possible to give expression to those subtleties which you always wanted in your dream project. The various permutations and combinations of architectural rendering techniques on the computer screen, a CD or even in print can give a very realistic shape to what you require in a building. Once you see the actual picture, you can get a clear-cut idea if the output is actually what you require or some changes would make it perfect.
Sometimes you just have to give information in electronic design format about your project along with your proposed budget, and you can get various best possible designs to choose from within just a period of one week or so. Computer based architectural rendering technologies have revolutionized the initial stage conceptualization, planning and designing of the project and eliminated the time consuming manual processes of making drawings which failed to come even remotely close to your aspirations of how you would like your dream building to appear.

For people who are studying architecture and those who are already in the profession, one of the most helpful tools that they can use is architectural rendering, which enables them to create two-dimensional images of an architectural design. Using such a tool enables architects to see how a structure will look even before construction begins, which makes it possible to make the necessary adjustments that are needed before building the structure. However, with the development of computer-assisted architectural rendering, architects can now make three-dimensional images of structures using their computers. Given this, architects can now come up with very realistic 3D images of structures, which can really help them accurately assess and modify the structure. However, this tool does not only create realistic 3D structures. Some of the software that is used in rendering provides very specific details, especially with the structure’s background and landscape.
3D plants
In the past, the technology used to provide the plants in architectural rendering used “
flat plants,” which were plants that were very chunky and would rotate as the structure is rotated. However, these kinds of plants were very unrealistic, as they would only show their front and did not cast any shadows. As a result of this, the companies that provide architectural rendering services tried to come up with more realistic plants that they could use in the rendering that they did for their clients. They were able to do so by combining 3D skills that are used for animation and computer games and by expanding both the software and the hardware that they used so that they could come up with an increased workload in terms of computing and bigger memory requirements. As a result, the plants that we see in architectural renderings nowadays look very realistic, as they are also based on actual plant species. Unlike their earlier flat predecessors, the plants now cast real shadows and look great from all angles.
In contrast to the chunky and unrealistic plants that were used in the past for computer-assisted architectural rendering, the plants that we see today in most virtual structures are lifelike. This is because the companies that provide architectural rendering services have taken the necessary steps, including using modern animation technology and equipment, to provide realistic plants based on real species, which enhances the overall look of the architectural renderings that they create.

3D architectural rendering has quite rightly become an important necessity for building construction. Wide utilities and better compatibility/performance make these 3D architectural rendering services much more effective than others. 3D architecture render gives better realistic views of buildings than any other services in the business today. Perhaps that’s why architects, builders and designers prefer 3D architecture rendering.
3D architecture rendering is used for creating three dimensional views of different building objects and parts. Such 3D views are so much realistic that you can clearly visualize your building as if it is already created and you are watching it. 3D architecture rendering will perfectly clarify about what you will require for your upcoming building construction activities.
It can be identified as a series of processes for creating 3D images/ 3D models from proposed building plans and structures. Different 3D images and 3D models, prepared from different angles with various dimensions will give you most realistic 3D views of your buildings. This will surely help you to easily build your building with better effectiveness.
3D architectural rendering services are helpful in many ways for building construction, such as:
• Architectural 3D exterior rendering for exterior views of your buildings
• Interior Rendering used in various fields such as office interiors, house interior etc
• 3D product rendering
• Architectural 3D visualization
• 3-D architecture animations and rendering
• 3-D architecture modeling rendering
• 3D landscape rendering services
• 3D Model rendering for different building structures like commercial, residential, industrial and institutional buildings
• 3D walk-through services
Above mentioned utilities of 3D architecture rendering is enough for making your building effective and better. 3D architectural rendering allows users to decide building design related issues well before it actually starts being constructed.

In the field of architectural design, 3D rendering has become an important selling tool, attracting a wide variety of clients, from architects to designers and property developers. 3D rendering can be used in numerous activities. It can prove useful when wanting to market new products, when showing interior design ideas or when you wish to visualize planning applications.
Among the many services that 3D rendering companies offer, the most common are interior rendering, exterior rendering, landscape rendering, site plan illustrations, 3D floor plans and animations.
If you want to market a newly built or renovated property, 3D interior design rendering might be just the thing you need. Weather it is a commercial or a residential property, the client needs to visualize it before purchase. In order for this to happen, 3D interior rendered images offer a realistic display of the exact features and designs that will be incorporated into the final product when the project is complete.
Opting for 3D interior computer rendering allows the specific products to be dropped into the virtual setting of the property in a very realistic manner. As a consequence, clients get to see a complete image including furniture, electrical items, bathroom and kitchen cabinets allowing them to make the purchase decision in a more informed manner, thus enhancing their satisfaction level.
Some companies offer 3D interior design rendering to clients that want to renovate their homes using their own choice of furniture, artwork and surfaces, textures and fabrics. Some computer rendered images can even be animated so as the clients can be walked through each section of the project. It gives a more realistic feel to the whole application. This service is often used for new designs of apartments, lobbies and commercial facilities.
Interior designers can benefit a great deal from 3D computer rendering. Since they are faced with the ordeal of getting their ideas across, there is always the danger of not being clear enough, despite the numerous sketches that they present to their clients. The reality is that clients can’t read plans and sketches. They need to actually see it. Especially when there are changes that need to be made. It is very easy to make alterations to an image so that the client can get exactly the design he desires.
There have been troubles to what the cooperation between designers and 3D artists is concerned. The 3D artists had problems understanding briefs while the designers still had a hard time grasping the concept of 3D image rendering. Despite all this, progress has been made starting with the simplification of the whole process. Nowadays, interior designers have access to a complete 3D rendered catalogue and library of decoration and furniture items that allow them to fill a scene regardless of whether that item is actually in stock or not.
Creating the dream home is now possible through 3D interior design rendering which takes companies one step closer to providing the ultimate customer satistfaction services. One can get a better and more realistic understanding of what his house will look like before the project is even complete. This way both client and company are better focused and know exactly what they need to do.
