Method Detail

normalize

public static void normalize(java.nio.FloatBuffer normals)

Normalize the normals in the given buffer, which is assumed to contain the (x,y,z) coordinates of the normals. If there are normals that have nearly zero length, they will be replaced by an unspecified default, and a warning will be printed.

This is done specifically for glTF, because non-normalized normals are reported as an error by the validator.

Parameters:

normals - The normals buffer
