Hi Community, I had some discussion and coding some sample with Wojtek's help 2010 :-). It is about a sample code that illustrates a simple lights and obstacles. It become actual for me again so I started with this archived example as a testbed to work on it and integrate it into much larger project. Here is the link of the code:
http://markmail.org/message/ccscbkzyxsgmb5vl#query:+page:1+mid:c542rbpj3jdw3v5d+state:results I know it was working till recent times. And it doesn't anymore :-/. So I went to see what might have changed in OpenGL and OSG since then (bit crazy but I had to start somewhere). It uses shadow2DProj which I found it was replaced by the texture call in GLSL after 130. Also on OSG side to use the built in uniforms I know it has to be enabled in the camera's gc state with setUseModelViewAndProjectionUniforms. So far these were my findings which didn't helped. I would like to ask you for any hints and for a bit of will to see if someone can spot something - the code is simple, selfcontained, it has lighting from the red book implemented and use simple shadow mapping to make the lights to not appear behind obstacles. As always, thanks a bunch!!!!! Cheers, Nick -- trajce nikolov nick
