It seems that the viewmatrix (w2c) in GaussianRasterizationSettings is not differentiable. When traversing through grad_fn.next_functions.

Thanks for your great work!
When i read the code, i have following question.
With camera moving, the viewmatrix of camera is changing,and thus the projmatrix is changing.
But in the code, with came…

Recently, I've been quite confused by matrix multiplication. I noticed that in forward.cu, the normal is calculated by multiplying it with the viewMatrix, which transforms the normals into camera spac…

Hi, thanks for your great job!
Here I want to use the extrinsic and intrinsic of static camera and gripper camera to calculate the point-cloud in the world coordinate. Can you tell how to get thes…

Hi, thanks again for open-sourcing this rasterizer. The `README` file mentions that the rasterizer should be called using:
`render(..., viewmatrix=w2cT, fov=(self.half_tanfovx, self.half_tanfovy), HW…

Hi i have this for map render:
```
var viewMatrix = ScreenManager.Instance.Camera.GetViewMatrix();
var projectionMatrix = Matrix.CreateOrthographicOffCenter(0, ScreenManager.Instance.…

Thanks for your reply to the previous issue.
I've got some other questions.
(1) I have a set of face images, but I don't have other information such as camera parameters.
How can I extract intrin…
