Hi!
After updating the osg version from the svn which do
include the geometry shader implementation I got
always an OpenGL invalid value error. (nVidia driver
100.14.1)
The error is located in the Program.cpp in the line
2667:
_extensions->glProgramParameteri( _glProgramHandle,
GL_GEOMETRY_VERTICES_OUT_EXT,
_program->_geometryVerticesOut );
Here the default value of _geometryVerticesOut is set
to 0, which do cause problems on my system. Changing
the default value to 1 in the constructor line 2319:
Program::Program() :
_geometryVerticesOut(1),
_geometryInputType(GL_TRIANGLES),
_geometryOutputType(GL_TRIANGLE_STRIP)
{
}
doesn't break any rendering (I do not use geometry
shaders at now) and removes the invalid value error.
Could somebody please chek this.
Best regards,
Art
