Re: [osg-users] How to set the size of a point in osg?
Try something like this: averageGeom-getOrCreateStateSet()-setAttribute( new osg::Point( 3.0f ), osg::StateAttribute::ON ); Glenn Waldron : Pelican Mapping : http://pelicanmapping.com : +1.703.652.4791 On Thu, Nov 20, 2008 at 5:02 PM, Ruqin Zhang [EMAIL PROTECTED] wrote: Hi, I couldn't find any function to set the point size, can anyone help?

While, is there any function that I can change the size to what I want? Thanks a lot!

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.

Thanks guys. Then how about Line? Seems there is no osg::Line. Thanks!

Look at osg::LineWidth Glenn Waldron : Pelican Mapping : http://pelicanmapping.com : +1.703.652.4791 On Thu, Nov 20, 2008 at 5:40 PM, Ruqin Zhang [EMAIL PROTECTED] wrote: Thanks guys.
