If you look at the code here:
http://trac.openscenegraph.org/projects/osg//browser/OpenSceneGraph/branches/OpenSceneGraph-3.0/src/osgPlugins/ac/ac3d.cpp#L1157
it appears that the light being added IS specified in the AC3D file, so
OSG is adding the light, as directed.

Well, OSG does handle more than triangles (QUADS, TRISTRIPS, etc) but
modern OpenGL actually only handle triangles internally and trianlges is
what it renders best. Are you asking if OSG supports pure CSG primitives?
it does not, because OpenGL does not.

Re: [osg-users] Triton Ocean
You should be able to see my email address in the headers. xe...@alphapixel.com. In order to have breaking shore waves in Triton, you need to supply it with a raster image of the bathymetry (sea floor) underneath the water surface, as well as a texture matrix that allows for transformation of a world coordinate into the texture space of that raster. Triton will then use this information to modify the waves as they approach the shallow shore areas to make them larger, and break on the shoreline. http://www.sundog-soft.com/docs/triton/terrain.html "OpenSceneGraph users may refer to the OSGDynamicHeightMap sample included with the SDK. This sample generates a height map from the scene surrounding the camera automatically, and feeds it to Triton for smooth coastline blending. This sample also includes code for a vertex program that can compute accurate height map data for geocentric or ECEF terrains." ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] compositeviewer, close and remove view
Hi, I have a compositeviewer with multiple views. One of them has a windowmanager with canvas window. My problem is that after i closed the window, the view is still present (getNumViews() was not decreased). And even if i call removeView() the canvas reference is not deleted. I want to close and readd the same window/view during runtime. Maybe i can catch the CLOSE event, call removeView + set my canvas reference to null. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=69683#69683 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
