3D Primitive and Composite Transformations
Previously you have studied and implemented 2D geometric transformations for object definitions in two dimensions. These transformations can be extended to 3D objects by including considerations for the z coordinate. In this unit, you will study certain methods to implement such transformations.
You must have noticed here that the translation is as simple as in 2D. Rotation however requires a little more effort in 3D. Standard rotations about three coordinate axes are simpler to perform. In order to apply rotation about an arbitrary axis, you need to have a composite transformation while scaling, shear and reflections are generalized to 3D in a natural way.
Graphics Tablet - CAD and CAM We need to know what we mean via tablet in computer terminology, before going into details on the graphic tablet, since in the other disciplines
Define coherence properties? A coherence property of a scene is a part of a scene by which relate single part of the scene with the other parts of the scene.
Suppose here, one allows 256 depth value levels to be employed. Approximately how much memory would a 512x512 pixel display necessitate to store z-buffer? Solution : A system w
