rasterize_gaussians gradient #1059

Open NimbusLongfei opened 2 weeks ago

NimbusLongfei commented 2 weeks ago

Can't we use this function rasterize_gaussians to get the gradient of the pose of the view camera in raster_settings?

If I want to do this, is it mathematically derivable?

That's means the camera pose become a variable. It is possible to do a backprop. However, the current rasterizer assume the camera pose is a constant. You can check out the backward pass.
