There are thousands of rays and triangles. We need to get all the intersections. If we use a normal two-level loop, we need O(mn) time complexity. Is there How to reduce the time complexity from O(

Algorithm – The minimum spheres of the triangle in 3D?
First, I think you add the vertex and the scale by 1/3 to find the origin and then the maximum distance from the vertex to the origin. This will produce a sphere containing triangles, but it doesn’

iPhone – OpenGL ES How to Import 3D Models at runtime and map the texture to it
It’s a bit cheating because there are actually two problems in the title.
As for how to import the 3D model, I think I can pass this .
However, my question is: Can I map textures to imp
