Modeling primitives,Human beings live in a 3D world, but when they draw they work with a 2D representation of the 3D world. There are two approaches to this:

Free-form curves and surfaces,The design of curves and surfaces plays an essential role in the construction of 3D objects for image synthesis. Although many objects may be constructed by assembling geometric shapes like cubes, spheres, or pyramids, most objects have a free-form shape, e.g., human faces, car bodies, airplanes, shoes, clothes, clouds, mountains.

Complex light-source and illumination models,As discussed by Verbeck and Greenberg (1984), a complete intensity calculation must incorporate light-source properties and environmental shadowing effects. An accurate description of physical characteristics of light sources should include three attributes to be modeled:

Antialiasing and motion blur,A phenomenon called . is a major problem in image synthesis. The term refers to the fact that this phenomenon occurs when a low-frequency signal appears as an “alias” of a high-frequency signal after sampling. Practically, this means that resolution in the object space is infinite when compared with resolution in the display space.

Optimization techniques for ray-tracing,As previously explained in Sect. 10.1.4, various approaches have been developed to speed up ray-tracing. These may be classified into two categories:

Combination and composite images for complex 3D scenes,A complex 3D scene should probably be modeled and rendered using several different methods. For example, consider a scene with the sea, trees, a mountain, a ship, and clouds. Based on the preceding chapters, we would normally choose the following methods:
