Int32

The sampling kay used for the Lut

Attributes

Remarks

Create a Lut entry.

1D Lut(s) are treated as gain curves.

3D Lut(s) are used for direct color manipulations.

For 3D Lut(s), the values should be normalized to the range 0.0 to 1.0, inclusive. And 1.0 is the maximum panel luminance. And If N is the size of each dimension, the data is arranged in RGB order:

R(0, 0, 0), R(0, 0, 1), ..., R(0, 0, N - 1),
            R(0, 1, 0), ..., R(0, 1, N - 1), ..., R(0, N - 1, N - 1),
            R(1, 0, 0), ..., R(1, 0, N - 1), ..., R(1, N - 1, N - 1), ..., R(N - 1, N - 1, N - 1),
            G(0, 0, 0), ..., G(N - 1, N - 1, N - 1),
            B(0, 0, 0), ..., B(N - 1, N - 1, N - 1)

When a GPU shader samples 3D Lut data, it's accessed in a flat, one-dimensional arrangement. Assuming that we have a 3D array ORIGINAL[N][N][N], then

FLAT[z + N * (y + N * x)] = ORIGINAL[x][y][z]
