Hello, First time posting.
We developed an OSG based viewer using OSG 3.0.1. Recently, I upgraded to using OSG 3.2. We have a geometry shader that implements a billboard for trees. Even though I can still see the trees, they are no longer aligned with the line of sight (i.e. don't rotate to align normal with los). OSG does issue a warning when it renders with this geometry shader: OGL error is 1282 (i.e. generic INVALID operation error). Now nothing in our code has changed before I upgraded to OSG 3.2. I did notice that the offending call seems to be EmitVertex(), since if I omit that from the shader, I don't get the 1282 error, but obviously no billboards either. Would anybody in this forum be able to provide some hints on how I can fix this issue? May be something that needs to be done differently when using OSG 3.2? Thanks in advance, Paulo ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=58666#58666 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
