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.
Computer Animation Tools To create various types of animation discussed above, we want to have particular software and hardware as well. Here, the fundamental constraint is re
Objectives of Three dimensional transformations explain basic 3D transformations-translation, rotation, scaling, shear and reflections-applied to objects in space; ex
Projections - Viewing Transformation Specified 3-D object in a space, Projection can be explained as a mapping of 3-D object into 2-D viewing screen. Now, 2-D screen is termed
Q. Why are all resolutions in ratio of 4:3? The bad news is that almost every monitor can only display upto a maximum of 262,144 colours (i.e. 18 bits/pixel Colour Depth). The
