EZ_Vertex23fv
specifies the coordinates of a vertex and
EZ_Normal3fv
specifies the normal vector at a vertex.
Arguments are either 2 floats or 3 floats or a pointer to 2 or 3
floats. The normal vector is used in lighting calculations.
For example, the following sequence specifies a rectangle.
EZ_Begin(EZ_QUADS); /* begin individual quads */ EZ_Normal3f(1.0, 0.0, 0.0); /* set the normal */ EZ_Vertex2f(0.0, 1.0); /* the first vertex */ EZ_Vertex2f(1.0, 1.0); EZ_Vertex2f(1.0, 0.0); EZ_Vertex2f(0.0, 1.0); EZ_End(); /* end the current object */
