Hello Mike,
Are you getting any InfoLog messages from the GLSL compile or link?
No, I am not getting any messages. If I voluntarily introduce an error
in one of my shaders, then I get the error message on the console. But
otherwise it all runs fine.
Another point is that it all runs fine, no crashes or anything, so I
guess my allocation of the Vec4Array and all that is ok... Can you
spot anything wrong there?
Note that there was an error in my original post,
osg::ref_ptr<osg::Vec4Array> colors =
new osg::Vec4Array(normals->getDataSize());
should have been
osg::ref_ptr<osg::Vec4Array> colors =
new osg::Vec4Array(vertices->getDataSize());
(my original code works on normals but for the sake of posting the
code to the list I changed it to vertices)
BTW a working example of GLSL generic attributes is the diffraction
shader in
http://osgtoy.svn.sourceforge.net/viewvc/osgtoy/osgtoy/trunk/osgtoy-data/compactdisc.osg It binds a "tangent" attribute to slot
5.
I'll check that out. Can I just display the osg file with osgviewer,
or do I need osgToy?
Thanks,
J-S
