CS 635 Spring 1998 : Advanced Computer Graphics

Lab 2: Texture Mapping

Due Sunday April 12, 1998.

Purpose:

To gain experience implementing texture mapping techniques.

Assignment

color_type: 8 filename u_res v_res per_face/wrap_map

per_face says to use inverse-bilinear mapping to each face, wrap_map says to wrap the texture around the object.

normal_type: 8 filename u_res v_res per_face/wrap_map

apply the texture map as a bump map, modifying the surface normal. For this, only polar coordinate mapping is required.

Extra Credit

• 10% for implementing specular mapping.

• 25% for implementing displacement mapping as a pre-process in the renderer.

• 35% for implementing environmental mapping (using 6 renderings of the scene. You must create the 6 rendered images from the appropriate viewpoint and also create the sample input to show that your technique works correctly.
