Most of the 3D models we’ll render are made of thousands to millions of triangles so it’s very ray-triangle-intersection calculate the intersection of a ray and a triangle in three dimensions using the Möller-Trumbore intersection algorithm with culling enabled Is the intersection point inside of the triangle’s perimeter, or outside? Are the ray direction and the 3d plane parallel to one another? Is the triangle “behind” the ray? This method is passed three vertex positions and (optionally) three vertex normals and should test the intersection of the ray against the triangle. //!
