Hello,
i have just recognzied, that recently the behaviour of VRML loading
changed (current CVS):
So far, if no appearance was defined for a shape, the geometry was unlit
(no shading, pure white).
I rely on that, as I use the color of triangle as index for an array
lookup.
I am willing to change my code, but im not sure what exactly to do.
Change the "now automatically created" default materialgroup before each
geometry to what? zero diffuse, zero specular, full ambient?
Or should i remove it?
I think the best fix would be to add an Appearance to your VRML
models. ;)
Could do it, but which one?
If you can't do that, replacing the Material in the default
MaterialGroup with one that either has full ambient or full emission
(the former is scaled by other lights, the latter isn't) should work.
I tried both, neither is what i want.
I want an unlit model. I define color per Vertex in the geometry and
want the rendered model to show exaclty the defined color, without
any change. Just like having a geometry without any material and no
lighting.
I even tried to set the Material of the MaterialGroup to osg::NullFC,
but that seem to result in a undefined behaviour ;)
Please help,
else i have to go back to an old cvs...
Daniel
Yours
