warp.volume_index_to_world_dir#

warp.volume_index_to_world_dir(
id: uint64,
uvw: vec3f,
) → vec3f#

  • Kernel

  • Python

  • Differentiable

Transform the direction uvw from the volume’s index space to world space using the linear part of the volume’s affine transform.

For positions, use volume_index_to_world() instead.

Parameters:

  • id – The id of a warp.Volume.

  • uvw – Direction in index space.

Returns:

The transformed direction in world space with float32 precision. Translation is not applied, and the vector is not renormalized, so a scaling transform changes its length.

See volume_index_to_world() for a usage example.

warp.volume_index_to_world_dir(
id: uint64,
uvw: vec3d,
) → vec3d

  • Kernel

  • Python

  • Differentiable

Transform the direction uvw from the volume’s index space to world space using the linear part of the volume’s affine transform (float64 precision).

The float64 overload of volume_index_to_world_dir(). Behavior and usage match the default float32 overload; see it for details and a usage example.
