warp.volume_sample_grad

warp.volume_sample_grad(

id: uint64,

uvw: vec3f,

sampling_mode: int32,

grad: Any,

dtype: Any,

) → Any

Kernel

Differentiable

Sample the volume given by id and its gradient at the volume local-space point uvw.

Interpolation should be warp.Volume.CLOSEST or warp.Volume.LINEAR.
