I have a similar problem, but simply tricking the ambient light is not enought. I have a particle system to simulate snow.
I have two GL lights. One is the normal daylight (sun) that defines my ambient/diffuse light. The second light is a spotlight simulating the car head light, which should illuminate only the snow flakes that are right inside the light cone. I was trying really bad to make my GL lights influence my particles, but with zero success. How can I implement my spotlight solution? ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50950#50950 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
