Function ortho

ortho(left, right, bottom, top, near, far, dst?): Mat4
Computes a 4-by-4 orthogonal transformation matrix that transforms from the given the left, right, bottom, and top dimensions to -1 +1 in x, and y and 0 to +1 in z.
Parameters
- left: number
  
  Left side of the near clipping plane viewport.
- right: number
  
  Right side of the near clipping plane viewport.
- bottom: number
  
  Bottom of the near clipping plane viewport.
- top: number
  
  Top of the near clipping plane viewport.
- near: number
  
  The depth (negative z coordinate) of the near clipping plane.
- far: number
  
  The depth (negative z coordinate) of the far clipping plane.
- Optional dst: Mat4
  
  Output matrix. If not passed a new one is created.
Returns Mat4
The orthographic projection matrix.
