Hi,
I have 3D object presented by its surfaces,Each surface is the polygon with n vertexes.
For every vertex 3 coordinates are given :(x,y,z),when -1<=x,y,z<=1
I need to draw the object…How can I do it,using perspective projection
Then go for next page http://nehe.gamedev.net/lesson.asp?index=02
You don’t need the texturing part, but there is perspective projection and hidden surface removal (through depth testing and the zbuffer).
