Re: [osg-users] shadows and custom shaders

Hi guys, So I have been reworking to support the shadows. Does the tex gen coords get stored in the texture matrix? Am I wrong to assume I can still use the fixed-function tex gen coords with a shader? Werner, I noticed you said you replaced the OSG shader with your own. Do you happen to

Hi Michael, So I have been reworking to support the shadows. Does the tex gen coords get stored in the texture matrix? Am I wrong to assume I can still use the fixed-function tex gen coords with a shader? Texture coordinate generation is done by the Vertex stage, so as soon as you start

Re: [osg-users] shadows and custom shaders

Thanks J-S. Yea I finally got it working. I did it by taking over the cull step of the shadow maps and getting rid of the fixed function tex gen and then pushing the matrices for the shadow projection into my vertex shaders and doing the math there. Thanks for your help. --

[osg-users] shadows and custom shaders

Hi, So I have been experimenting with shadows in OSG using the ShadowMap shadow technique. With the default OSG implementation and every custom shader in my scene graph disabled the shadows work correctly. Once I turn my shaders on they stop working. This is understandable as he OSG shadow

Re: [osg-users] shadows and custom shaders

Hello Michael, If I am implementing custom vertex shaders should I be overriding the ShadowMap and not allowing that TexGen to be created and then generate the proper texture coordinates in my vertex shader? At this point I think all that is missing is the proper texture coordinates for

Hi J-S, Thanks for the swift reply, good to know I was on the correct path. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=31904#31904 ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] shadows and custom shaders

Hi Michael, You are right. There can only be one shader program loaded which has to do all the work. If you overload the default shader from osgShadow, it has to do that work together with your new stuff. In my case I just created my own class Cl_SoftShadowMap, derived from osgSoftShadowmap.
