a given transform to an image, the color management system instructs a CTL
interpreter to load and run the CTL program that describes the transform. The
original and the transformed image constitute the CTL program's input and
output.")

(description
"BRDF Explorer is an application that allows the development and analysis
of bidirectional reflectance distribution functions (BRDFs). It can load and
plot analytic BRDF functions (coded as functions in OpenGL's GLSL shader
language), measured material data from the MERL database, and anisotropic
measured material data from MIT CSAIL. Graphs and visualizations update in
real time as parameters are changed, making it a useful tool for evaluating
and understanding different BRDFs (and other component functions).")
