Hi I am using directx9 But i have some problem of face . I really don't know how to handle this problem. I am showing some Ascii Work for my problem Take a figure-1 look this one cube that loading from .x file But i don't Why it's render face 1,4 . I had seen some programe like deep exploration that not rendering this faces.Basically i am showing solid+outline object.I had checked in also directx7 retain mode sample has also not rendering 1,4 face. So why directx9 rendering this face.


 1-----2    
 | \   |
 |  \  |
 |   \ |
 3-----4
 figure-1

In deep exploration or Directx7 retain mode sample rendering like this in same file figure-2


 1------2
 |      |
 |      |
 |      |
 3------4
 figure-2

My faces structure like this 3:1,2,3,4, so it is has more than 3 faces in one line of .x file. So any good suggestion and help require :) thanx

With D3DRS_CULLMODE, you can remove faces that have clockwise or counterclockwise vertices. In other words, faces that are facing the other way.

Direct3D can only handle polygons of 3 vertices, so only triangles.
