glVertex commands are used within glBegin/glEnd pairs to specify point, line, and polygon vertices. The current color, normal, texture coordinates, and fog coordinate are associated with the vertex when glVertex is called.
When only 𝐱 and 𝐲 are specified, 𝐳 defaults to 0 and 𝐰 defaults to 1. When 𝐱, 𝐲, and 𝐳 are specified, 𝐰 defaults to 1.
