Program Description

Phase 1

You are required to implement all steps in OpenGL transformation pipeline. You are also required to implement back-face culling, view frustum culling. Then draw a wireframe of the object.

Bonus

Phase 1

• Implement view frustum clipping.

Phase 2

• Implement Phong shading.

Examples

There are some test cases. You can download it to test your program. Your program should get the file name from user. For example, when the program starts, it should ask the user to input the file name. If the user type "box", then the program should load box.obj, box.view.

example 1:
box2.obj box2.mtl box2.view
wireframe

Guard shading

Phong shading

example 2:
psx.obj psx.mtl psx.view
wireframe
