I have drawn three cubes in my mobile app. but how to set the projection or translation to make this three cubs laid on my screen.
I have tried:
- set the frustum 's parameter bottom to zero to make it look from the same direction. (because we can’t see the back of the cube )
- set the all objects’ z to same value in translation. ( i don’t sure it’s right")
but the three objects don’t looks on the same plane.
I want the effect like this
