It additionally loads any referenced material and texture files. Instead of calling a GL procedure to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and colors and use them to construct a sequence of primitives with a single. Between the GL commands you inject between glNewList() and glEndList() and the work that gets executed when you call glCallList() is a lot of GL driver CPU-side voodoo.
