fill_projection_matrix   xtlang


Defined in:  https://github.com/digego/extempore/tree/v0.8.9/libs/external/opengl.xtm

Implementation

;; this is similar to gluPerspective
;; but fills a suitable PROJECTION matrix
(bind-func fill_projection_matrix
  (lambda (mat:float* fovy aspect near far)
    (let ((top (* near (tanf fovy)))
          (right (* top aspect))
          (left (* -1.0 right))
          (bottom (* -1.0 top)))
      (pfill! mat
              (/ near right) 0.0 0.0 0.0
              0.0 (/ near top) 0.0 0.0
              0.0 0.0 (/ (+ (* -1.0 far) near) (- far near)) -1.0
              0.0 0.0 (/ (* -2.0 far near) (- far near)) 0.0)
