master_pattern_grid

de_ebsd.core.master_pattern_grid(npx, device=None, dtype=torch.float32)

Northern-hemisphere unit vectors for every master pattern pixel.

Returns a tensor of shape (2 npx + 1, 2 npx + 1, 3) where element [row, col] is the direction whose square Lambert projection is X = (col - npx)/npx * L and Y = (row - npx)/npx * L. Negate the z component for the southern hemisphere.
