Thanks Brede and Gordon -- No sweat, Gordon -- osgSim::LightPoint objects are already supported in the exporter.
I guess my dilemma at this point, which might not have been clear in my last post, is this: If I am to rewrite the backend of the exporter to provide better and more efficient Mesh support, then why would I ever need to export a Face record? And consequently, why would I use the Vertex Palette? And it turns out I need to use the Face record for Billboards, and also use the Vertex Palette to store the vertices of Light Points. In a separate thread, Jason Daly (I think) pointed out that I could also support POINTS as 1-vertex Face records. Similarly, I could support LINES, TRIANGLES, QUADS, and POLYGONS as 2-, 3-, 4-, and n-vertex Face records. Pretty much everything else would be a Mesh. Does this sound like the right way to go? Diving into the code today, hopefully (though I'm fighting off a cold, so who knows how much progress I'll make). -Paul > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Gordon Tomlinson > Sent: Monday, March 31, 2008 9:52 AM > To: 'OpenSceneGraph Submissions' > Subject: Re: [osg-submissions] FLT export: minor fixes > > Err 'light point record' ? > > Theres extra work to save in to the file as a light point is > more than just a vert in OpenFLight... > > ( see pages 38-42, 146-150 of the 16-3a spec , op code 130,111,131) > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Jason Daly > Sent: Monday, March 31, 2008 11:33 AM > To: OpenSceneGraph Submissions > Subject: Re: [osg-submissions] FLT export: minor fixes > > Paul Martz wrote: > > The warning about GL_POINTS is valid -- No way to create point prim > > itives in a FLT file, so they get dropped with warning messages. > > > > I thought a point was just a face record with one vertex.
