Hi Antoine, I'd recommend just using the vertex attribute arrays in osg::Geometry to setup multiple sets of vertex data.
I'd also strongly recommend against using independent index arrays for vertex attribute array as this forces the osg::Geometry rendering code to drop down to OpenGLslows paths for dispatching the data, as OpenGL itself doesn't support independent indexing of vertex arrays.

Hello, It seems possible to have two sets of colors for geometries with setColorArray and setSecondaryColorArray and swap between them when needed. I would like to use this feature to have a normal color for the wireframe of the mesh I display and another color when selected, but I don't understand how to swap between both color arrays (I assume it has to do with AttributeTypes but how?). And if I use secondary colors, must I also define secondary color bindings, color indices. Moreover, if I wanted to have a third color (or more) to hightlight other modes, anybody knows how I could change the color of my mesh during runtime? Thanks, Antoine. PS ; sorry if you received this mail twice, seems I have a pb with my mails... _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
