Fields§

§colors_sh_grad: B::FloatTensorPrimitive

The shape is [P, M * 3] <- [P, M, 3]

It is the gradient of colors_rgb_2d with respect to colors_sh.

§opacities_grad: B::FloatTensorPrimitive

The shape is [P, 1]

It is the gradient of colors_rgb_2d with respect to colors_sh_degree_max.

§positions_2d_grad_norm: B::FloatTensorPrimitive

The shape is [P]

It is the gradient norm of the 2D positions.

§positions_grad: B::FloatTensorPrimitive

The shape is [P, 3]

It is the gradient of colors_rgb_2d with respect to positions_3d.

§rotations_grad: B::FloatTensorPrimitive

The shape is [P, 4]

It is the gradient of colors_rgb_2d with respect to rotations.

§scalings_grad: B::FloatTensorPrimitive

The shape is [P, 3]

It is the gradient of colors_rgb_2d with respect to scalings.
