Jun 12, 2025 · I also occurred this, that is a bug in the 3dgut method. May I ask, besides ignoring the gradient of this variable, are there any other good solutions? Or should we just wait for the official …

Feb 1, 2024 · In order to re activate camera pose opt in nerfstudio, I cherry pick the gradient backward proposed in branch : https://github.com/nerfstudio-project/gsplat/tree/vickie/camera-grads

Hello, I happened to compare the pose optimization gradient between 3dgs and 2dgs. I found that viewmat has always 0.0 gradient. A minimal example can be found as blew.

May 7, 2025 · Where is the gradient computation for camera poses implemented in GSplat? #668 New issue Closed caikunyang

Aug 28, 2024 · It seems splitting info ["means2d"] modifies the custom gradient computation in the backwards pass that would normally happen with absgrad=True.

Jul 1, 2024 · I've checked the inputs and all the tensors are guaranteed to be not nan, but when I tried to calculate the gradient of render_outputs or alpha over gaussian params (e.g. scales), nan values …

Apr 12, 2025 · Summary In compute_ray_transforms_aabb_vjp, the gradient of ray_transform for degenerate Gaussians (v_means2d [0] != 0 || v_means2d [1] != 0) seems to be off from the original.

Jan 5, 2024 · I'm recently reading your paper (Mathematical Supplement for the gsplat Library) and have one question about the derivation of the view matrix gradient. I understand the gradient of the view …

Jul 23, 2024 · I have a question on implementation. In DefaultStrategy, GS growth is done with a comparison of a threshold and a gradient norm. The calculation of the gradient norm is finally done …

Oct 24, 2024 · After a lot of trial and error I think the gradient is computing well now, however I still do not know a good procedure to tackle this task: how to modify/add the derivative in the backward step …
