Report

The test is just the opengl based application rendering an editable quadratic curve. It can be moved the control points of the curve in real time. The approach is the same as the one used by Loop and Blinn in the Gpu Gems 3 chapter and in the paper.

Originally I was going to render a cubic curve too, but I didn’t have time to do it. Maybe in a next test.
