Lab 3

Build and run the following sample projects. Study the documentation inside each sample project, which is in the form of an html file.

• Shader Series 1: Vertex Lighting Sample
• Shader Series 2: Textures and Colors Sample
• Shader Series 3: Per-Pixel Lighting Sample

Assignment 3

(1) Read Shader Series: Introduction.

(2) Read Shader Series: Coordinate Spaces.

(3) In the vertex lighting sample project, add an additional directional light.

(4) In the vertex lighting sample project, render the object in greyscale by averaging the color components in the pixel shader.

(5) In the textures and colors sample project, create a textured 3D model in Blender or other 3D modeling software and view it using the sample code.

(extra credit) Create an example project that illustrates specular maps as described in the section Extending the Sample at the bottom of the documentation for the per pixel sample project.

Demonstrate your solution to an instructor in a lab session. (Due end of week 4)
