1. • Write a matrix for a 2x2 square in the x-y plane centered at the origin. Use 3D homogeneous coordinates.
2. • Write the equation that rotates the cube 270 degrees about the x axis.
3. • Write the order of spaces in the display pipeline.
4. • Draw a picture that shows how ray tracing can make one shape cast a shadow on another.
5. • Consider the triangle: A = (0, 5, -2) B = (2, 0, -2) C = (0, 0, -3) The camera is at (0,0,0). Does the camera see the triangle?
