empty-normalIndex.x3d

Test of normal field set not NULL, the normalPerVertex field is set to F ALSE and the normalIndex field is set to empty. Under these conditions the normals are applied to each face in the same order given by the normal field. Normals for the front, left and right faces are defined with the same orientation as the face, therefore these faces should be visible as the figure is rotated. Normals for the top, bottom and back faces are defined to point towards the inside of the cube, therefore these faces should not be visible at any time.
