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.
consider a mesh
Image Capture Formats: Video cameras appear in two various image capture formats: progressive and interlaced scan. Interlaced Scan It is a technique of enhancing the
Shearing - 2-D and 3-D transformations Shearing transformations are utilized for altering the shapes of 2 or 3-D objects. The consequence of a shear transformation seems like
Applications of Ray Tracing Thus, you might ask, just what practical utilizes does ray tracing have: a) For vision research, simulation of real-world phenomena, b) Medica
