[Robert Futrelle]

CSU540 Fall 2005 - Midterm topics

KEY TO A GREAT GRADE:  DO IT!
WORK OUT LOTS OF EXAMPLES!
NO COCKINESS ON TEST DAY.
NO CALCULATORS.

Six of the following seven topics will be included.

Diffuse illumination
	Given: normal, light direction
		reflectivity, ..
	Combine the directional factors
		light color and reflectivity spectrum
		plus ambient (same reflectivity ambient source)

Line drawing
	Hand walk the code to generate values.
	Plot them on a grid to confirm all is OK.
	Sec. 3.5

Ray tracing:
	Know how to derive the sphere intersection.
	Apply to real numbers.

Bezier curves:
	Give you points, and the equation.
	Draw, compute/estimate locations.

Triangle normals:
	Given A, B, C
	Get the sense right for the sense of the normal.
	Normalization computations needed.
	Includes a light direction (no colors).

Gouraud illumination:
	Qualitative (see exams)
	Exact comp possible, but qual. results OK,
		if properly explained.

Specular reflection:
	Cross-sectional diagram
	Phong equation.
