Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???
Hi Michael, this sounds good but I just tried and it seam without changing the OSG code it is not possible as well. The StandardShadowMap does not holds any instance of the StandardShadowMap::ViewData where the _stateset is kept.

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???
Well, you said you want osg::Program at StandardShadowMap.cpp:544. That osg::Program is set to _stateset just on the next line. So if osg::Program of _stateset doesn't work for you, there's no use exposing it. 2014-04-15 17:50 GMT+07:00 Trajce Nikolov NICK trajce.nikolov.n...@gmail.com: Hi Michael, this sounds good but I just tried and it seam without changing the OSG code it is not possible as well.

Knowing the problem a bit I think the question is how to access the osg::Program of the shader technique for binding vertex attributes like the binormal and tangents arrays.

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???
Hi Jaime, yes, I have such an example. If you have the bump mapping GLSL code ready you can mix it with the shadow map shaders and set it to your shadow mapping technique - there are methods like setShadowVertexShader/setShadowFragmentShader/setMainVertexShader/setMainFragmentShader Nick On Fri, Apr 11, 2014 at 10:50 AM, Jaime xatp...@hotmail.com wrote: Hi, Does anybody have any example where I could find any solution to combine shadow maps and other shaders, specially bump mapping??

Re: [osg-users] ShadowMap + Other shaders (bump, specular, etc) example???
Hi. Here's my example: https://bitbucket.org/kornerr/osg-deferred-shading ( http://youtu.be/AjWOSuLxZ68 ) It has 2 implementaions: plain OSG and EffectCompositor (not part of OSG). The basic idea behind my implementation is to: * render the shadow only information to texture; * do all the rest effects myself and then combine those with the shadow info. 2014-04-11 16:04 GMT+07:00 Trajce Nikolov NICK trajce.nikolov.n...@gmail.com: yes.
