How to get the coordinates of all 3D Gaussian points on the plane after each iteration

Hello, I checked the code and found that there is an all-zero matrix screen_point(means2D), which is used to store the gradient of the two-dimensional Gaussian ellipsoid, but when propagating forward, I found that this scree_point(means2D) is not passed into CUDA, which causes the array in it to be an all-0 matrix all the time, and can only get its gradient but not the coordinates Now I want to get the coordinates of all Gaussian ellipsoids on a 2D plane, is there any way to do it？

Hi! I have the same question with you. Have you figured it out?

Same question here? Please let me know if you've figured this out? I am trying to visualize all the gaussian splats in 2D projected onto my image plane

Hi, I have the same question, may I ask if the problem is sorted already?
