Pass the zfar and znear arguments to GaussianRasterizationSettings

Hi there !

This is the companion PR of the one I did in the 'diff-surfel-rasterization' repository, that you can find here.

This PR enables to actually take into account the znear and zfar camera parameters in the rasterizer, and hence to render some cool distance cropped image as you may find below.

Thank you, I would like keep the same interface as 3DGS for facilitating research. But it deed really helpful, I will consider to integrate it for a viewer in the future.

Does your zfar and znear work in rasterization? Aren't they already initialized by default in class Camera (nn. Module)?

Hi, even though the arguments znear and zfar are in the class Camera, they are not passed to the rasterizer. Instead, they are defined as a constant in a header. This implies that they don't have an effect on the frustum culling viewing condition.

Exactly.
