to_extrinsic_frame_field

iskra.directional.to_extrinsic_frame_field(uv: Tensor, tangents: Tensor, binormals: Tensor) → Tensor[SOURCE]

Reconstructs 3D vectors from complex frame field.

Parameters:

• uv (Tensor[Complex, [B, 2]]) – Frame field to be unprojected.

• tangents (Tensor[Float, [B, 3]]) – First basis vector.

• binormals (Tensor[Float, [B, 3]]) – Second basis vector.

Returns:

​ (Tensor[Float, [B, 4, 3]]) – 3D embedding of uv.
