Algorithm – thousands of lights with triangles in 3D space
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’
