- .. c:function:: bool glm_ray_triangle(vec3 origin, vec3 direction, vec3 v0, vec3 v1, vec3 v2, float *d)
- Möller–Trumbore ray-triangle intersection algorithm
- Parameters:
- | *[in]* **origin** origin of ray
- | *[in]* **direction** direction of ray
- | *[in]* **v0** first vertex of triangle
- | *[in]* **v1** second vertex of triangle
- | *[in]* **v2** third vertex of triangle
- | *[in, out]* **d** float pointer to save distance to intersection
- | *[out]* **intersection** whether there is intersection
