# Need help!How to customize a projection plain?

## Recommended Posts

Normally we just projection objects to z = X plain!
And now I want to projection an object to z = x + 1 plain.
How should I setup my projection matrix?

Are you refering to an orthogonal projection matrix?

there you can find out how to do it with xna aswell as the formula for it.

[code]
2/width 0 0 0
0 2/height 0 0
0 0 1/(zfarPlane-znearPlane) 0
0 0 znearPlane/(znearPlane-zfarPlane) 1

sorry for my mistake,not z = 1,x = 1 plain, but z = x + 1 plain!!means the projection is not parallel with z = ? plain
