C++ (Cpp) projection_ortho Examples

Example #1

File: camera.cpp Project: mflagel/asdf_multiplat

 vec3 camera_t::screen_to_world_coord(vec2 const& screen_coord) const
 {
     vec4 vp;
     vp.xy = viewport.bottom_left;
     vp.zw = viewport.size_d2 * 2.0f;
     return unProject(vec3(screen_coord, 0.0f), view_matrix(), projection_ortho(), vp).xyz;
 }

Example #2
