TITLE : Chapter 13. Evaluators and NURBS
You can use glEvalCoord1() with any values for u, but by far the most common use is with evenly spaced values, as shown previously in Exampleッ2-1. To obtain evenly spaced values, define a one-dimensional grid using glMapGrid1*() and then apply it using glEvalMesh1()........
