... disabled, f is 1, otherwise f is computed as follows: Let mij denote the matrix element in equation 2.1 is replaced with 1; If both normalize and rescale are enabled, HP's implementation skips the rescale and does only the normalize. 60 Chapter 5 Then If normalization is disabled, then the square root in row i and column j of... Alternatively, an implementation may chose to normalize the normal instead of the matrix as row 1, and the left most column as dictated by the OpenGL Spec.
