Ok... so I did what you suggested mostly... I took the osgshadow example, add my geometry and it worked. I added another shader on the root node of the scenegraph, because in my app, I do that. I took the shaders from ShadowMap.cpp and put them into vert/frag files and loaded them into their respective shaders. That worked too.
In my application, when I load those shaders from ShadowMap.cpp and use them, I see a change in the lighting but it isnt what I expect. Rather than the objects casting shadows on the terrain, it looks like a shdow is being cast over the objects, but it isnt'being cast on the terrain. The best way I can describe it is that it looks like the objects are in the sun then a cloud floats between the sun and the object... I dont think a picture will show what I mean, but here are 3 pictures with the shadow moving progressively to the left over the object... note the white building in the front gets darker. But now shadows on the terrain. cid:image001.png@01CA692E.7A38B7F0 cid:image002.png@01CA692E.7A38B7F0 cid:image003.png@01CA692E.7A38B7F0 W > -----Original Message----- > From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users- > boun...@lists.openscenegraph.org] On Behalf Of Jean-Sébastien Guay > Sent: Thursday, November 12, 2009 1:45 PM > To: OpenSceneGraph Users > Subject: Re: [osg-users] ShadowMap problem... > > Hi Wyatt, > > > Any suggestions? > > Not really.
