Opengl set projection matrix

When the perspective projection matrix is set up, then the distance to the near plan and far plane are set. In your case this is 1 for the near plane and 10 for the far plane: mat4x4_perspective (p, 1.57, width/ (float)height, 1,10); The model is clipped by the near plane. The model has to be in clip space. Web15 de fev. de 2010 · openGL/GLSL Projection matrix. OpenGL. glsl. matador February 15, 2010, 8:32am #1. Hi everyone.
