Just to be complete, you can also set it in the vertex shader by writing
to gl_Pointsize; however, in that case, you have to enable
GL_VERTEX_PROGRAM_POINT_SIZE by setMode(GL_VERTEX_PROGRAM_POINT_SIZE,
osg:: StateAttribute::ON); on a stateset.

Hi,
I couldn't find any function to set the point size, can anyone help?
Here is the code:
osg::ref_ptr<osg::Geometry> averageGeom = new osg::Geometry();
averageGeom->addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet:POINTS, 0, averageArray->size()));
In this way, it will draw the points based on default size. While, is
there any function
that I can change the size to what I want? Thanks a lot!
