Web3.1.1 OpenGL Primitives. OpenGL can draw only a few basic shapes, including points, lines, and triangles. There is no built-in support for curves or curved surfaces; they must be approximated by simpler shapes. The basic shapes are referred to as primitives .

WebIn OpenGL each vertex has it's own associated normal vector. The normal vector determines how bright the vertex is, which is then used to determine how bright the triangle is. When a surface is perpendicular to light, it is brighter than a parallel surface. glNormal sets the current normal vector, which is used for all following vertexes.
