coordindex_normal.x3d

 (.x3d scene, pretty-print source, statistics, info & logs, X3DOM home)

Test of normalPerVertex field is set to true and the normalIndex field is set to empty. Under these conditions the normals are applied to each vertex in the order given by the coordIndex field. A +Z normal is defined for the upper front vertices, a +Y normal is defined for all the bottom vertices, a +X normal is defined for the back right (uppermost) vertex and a -X normal is defined for the back left (uppermost) vertex. The test should generate a figure with the upper vertices illuminated the most. The top, back and bottom sides should be dark when facing the headlight directly from the front.
