3D Illustration is a 2d representation of a 3d object in the virtual world. The illustrators role is to convey in the best possible manner, the design of the structure, through a rendered perspective.

Modeling a building for architectural presentation and analysis is different from modeling cartoon character, aliens from distant planet. Nobody know what aliens look like so the modelers have an advantage in his interpretation. Almost everybody knows what a structure looks like, and those expectation should be met by the illustrator.

With the aid of the Architectural Software, the Architects, Interior Designers, and Industrial Designers – anyone who makes aesthetic decisions in 3-Dimensions, will find that 3D computer visualization is a very effective way of conveying design ideas.

Building a 3D illustration on a computer often highlights design problems, and can aid in the search for a solution, which are often overlooked during the design process.

3D Modeling Basic

There are a lot of ways to create your 3d modeling and almost everybody have their own way and technique of creating the same model. In architectural visualization, there are a few modeling types every illustrator needs to master in 3DS Max.

These are spline, shapes and meshes, although there are others namely NURBS, patches, they all cater for other industry, but a basic understanding of these modeling techniques will be useful in other parts of your 3d scene.

The basic foundation of every 3D scenes are the line works, which are provided by the architects or other design professional, in the form of hand-drawn plans or 2D Autocad drawings.

From there, it is digitized to form a spline or shapes, that can be used in the creation of primitives, compound objects, and other object that will complete the scene.

Some also prefer to model the scene in AutoCAD and export to 3DS max for the texturing, lighting, and rendering.

There are no basic rule to follow, whether using autocad or a 3D software, as long as you are able to produce the required output.

Since designers are used to the precision drawings of autoCAD, it’s no surprise that some illustrator engage in setting up the all the massing and modeling part in AutoCAD to take advantage of its accuracy in the 3D creation, and exporting them for rendering in 3DS Max later

Materials & Textures

Modeling is only the first step of creating Architectural Visualization. Materials and textures are the steps that attach a color and surface qualities to the 3D objects.

These textures comes from either scanned, painted, photographed, of actual materials and then projected on the 3D surface.

The main thing that you need to consider is the resolution of the bitmap that you will be using.

You must bear in mind that the bigger the bitmap, the bigger the file size, and your rendering will be slower. Analyze the scene, if the object is far away from the camera or is a minor element in the scene, you can use a smaller bitmap size.

Lighting & Rendering

Lighting and Rendering requires a keen eye for color and tone, as well as understanding of the technicalities and limitation of 3D Lighting Systems and Rendering Engines.

In order to achieve realistic Architectural Illustration, you’ll want to study basic photography, which is primarily a study of light and how it interact with surfaces and film, and cinematography, which deals with lights in motion.

Lighting in 3D requires a mastery of the basic light types – directional, point, ambient, area, and spot lights – as well as an understanding of how lights interact with surfaces and the creation of shadow in 3D.

You’ll need to have a firm grasp of how textures will be affected by their lights. Knowing color and how to get the right look for the frame is imperative in creating a photo-realistic scene.

Fabbers (a.k.a 3D Printers or rapid prototyping machines) are a relatively new form of manufacturing that builds 3D objects by carefuly depositing materials drop by drop, layer by layer. Slowly but surely, with the right set of materials and a geometric blueprint, you can fabricate complex objects.

Believe it or not you can build your own fabber, Fab@home is a site with all what you need to build your own fabber, Our goal is to explore the potential of universal fabrication: Machines that can use multiple materials to fabricate complete, active systems.
Inspired by this history, the goal of this project is to offer an open-source, low-cost, personal SFF system kit, which we call “Fab@Home”. The aim of this project is to put SFF technology into the hands of those same curious, inventive, and entrepreneurial citizens. In addition, through this Wiki web site we hope to inspire users of Fab@Home to exchange their ideas for applications and their improvements to the hardware and software with us and each other. Several machines are already in use.
