Оптимизация пересечения лучей с сетчатой моделью [закрыто]
Is there an optimized method to get all mesh triangles visible from a given point?
There is a mesh model of huge size and some point near this model. From the point rays are spread out conditionally on all 360 degrees. It is necessary to calculate the indices of all triangles on which rays from this point fall. The analogy of a video camera...
It is clear that the methods of intersection of rays with the mesh implemented in such libraries as trimesh or pymesh are ineffective on large models. A large model, in my case, is billions of vertices....
