Questions from class Notecards

Form of the midterm

• What topics/chapters/readings are on the exam?
• Are old exams available?
• Do I need to remember the forms of the matrices?
• What equations are important to memorize? (especially with lighting)
• Is lighting and shading included?

Projects

• Can the projects be posted earlier?

Projection

• We put the image plane in front of the focal point, isn’t it really behind (in the pinhole model)? (with nice pictures)
• Can you put a lens where the pinhole is?

Primitive-based graphics

• why not just start with atoms and photons and work from the ground up?

Visibility

• Is the Z-Buffer always the same size as the screen? Can there be compression?

Shading

• For per-pixel shading, do we need a normal per-pixel
• How do you do per-pixel shading if the pixels are in screen coordinates and the triangles are in something else?

Lighting

• Are the lighting equations the same for ray-tracing?
• Why would OpenGL need non-unit length vectors except to annoy us?
• Do the different lighting components blend aS+(1-a)D?

Kinematics

• Can we do an example?
