Expand description
3D colour LUT node loaded from an Adobe .cube or Resolve .3dl file.
The LUT is a size^3 grid of RGB output triples applied with trilinear
interpolation. The grid is stored red-fastest (idx = r + size*(g + size*b)),
which is the order a wgpu 3D texture expects (x = r, y = g, z = b), so the
CPU path, the GPU upload, and the shader all index it the same way.
