Description [src]
Replaces the current matrix with a perspective matrix for a given viewing frustum defined by 4 side clip planes that all cross through the origin and 2 near and far clip planes.
Parameters
- left
- 
            Type: floatX position of the left clipping plane where it intersects the near clipping plane. 
- right
- 
            Type: floatX position of the right clipping plane where it intersects the near clipping plane. 
- bottom
- 
            Type: floatY position of the bottom clipping plane where it intersects the near clipping plane. 
- top
- 
            Type: floatY position of the top clipping plane where it intersects the near clipping plane. 
- z_near
- 
            Type: floatThe distance to the near clipping plane (Must be positive). 
- z_far
- 
            Type: floatThe distance to the far clipping plane (Must be positive).
