[x3d-public] Color constraint wrong length X3DJSAIL? SFColorRGBA can be 4 floats I think. NOT set in code, AFAICT

good diagnostics, thanks

found and fixed error in tupleSize computation for S/MFColorRGBA when generating the X3DJSAIL code.  Correction will deployed later today.

Eye of the beholder I think!  The fields coolColor and warmColor are part of this node and visualization technique.

> The ToneMappedVolumeStyle node specifies that the associated volumetric data is to be rendered using the Gooch shading model of two-toned warm/cool colouring (see [GOOCH1], [GOOCH2]). Two colours are defined, a warm colour and a cool colour. The renderer shades between them based on the orientation of the voxel relative to the user. This is not the same as the basic isosurface shading and lighting.

all the best, Don
