[openvrml-develop] Re: Problems with normal vectors beeing not normalized

[<MSo...@ya...>]

Hi Braden,

I just found that all faces that are completely flat and do not have a
normal vector given with them (at least those with more than 3
corners) seem to be affected by this problem. E.g.:

geometry IndexedFaceSet {
solid FALSE
coord Coordinate {
	point	[
		 240 1202.43 935,
		 240 1200 935,
		 240 1129.8 924.729,
		 240 1065.49 894.776,
		 240 139.996 286.866,
		 240 73.0611 255.691,
		 240 0 245,
		 240 -56.4157 245,
		 240 15.1684 273.006,
		 240 124.899 309.851,
		 240 1050.4 917.761,
		 240 1121.92 951.076,
		 240 1200 962.5,
		 240 1202.43 962.5,
		]
	}
coordIndex [
 5,9,6,-1,
 9,8,6,-1,
 6,8,7,-1,
 0,13,1,-1,
 13,12,1,-1,
 1,12,2,-1,
 12,11,2,-1,
 2,11,3,-1,
 11,10,3,-1,
 3,10,4,-1,
 10,9,4,-1,
 4,9,5,-1,
]

Can you point me to the code where the normals for such things are
calculated?

Best regards,

Michael
