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.
Ray Tracing - Polygon Rendering and Ray Tracing Methods Basically Ray tracing is an exercise that is performed to attain the realism in a scene. In easy way Ray Tracing is a w
BlackJack is a popular card game played in many casinos. The player plays against the dealer aiming to reach 21 points, or a score higher than the dealer without exceeding 21. The
Background Texturing is like wallpapering; you are pasting an image onto the OpenGL Quad primitive. Recall that GL_QUAD is specified by four vertices. An image, or a texture,

3-D Modeling and Animation Tools: By 3-D modeling software, objects rendered in perspective show more realistic. One can produce stunning scenes and wander by them, choosing just
What is persistence? The time it takes the emitted light from the screen to decompose one tenth of its original intensity is known as persistence.
Transformation for Isometric projection - Transformation Suppose that P(x,y,z) be any point in a space. Assume as a given point P(x,y,z) is projected to the P'(x'y',z') on t
