Re: [osg-users] How to add shadows to deferred shading?

Hi, No shadow with 0,0,1 is a bug. I'm not sure where ist comes from. The length in the shader was a test I forgot to revert this change. -viewspacePosition.z shold be used instead in both cases. 1000.0 is my far plane, i write the depth value unormalized [near, far]. Thank you! Cheers, Marcel

Re: [osg-users] mixing OpenGL with OSG - textures

Hi Aurelien, I am seeing you are using custom API for the textures. My case was pure OpenGL (which I don;t think it makes any difference). I found the way to reuse the texture I am creating and only installing new Texture::TextureObject from my initial attempt. The not implemented release is

Re: [osg-users] How to add shadows to deferred shading?

Hi. I've been thinking some more about my misplaced shadows, and I finally came to realize that the fragment shaders of the first pass (that fill G-buffers) produce fragments in Screen space, not in World space, and thus all G-buffers contain Screen space fragments. That's why shadow Screen space

Re: [osg-users] How to add shadows to deferred shading?

Hi, In your current implementation you store your fragment positions in world space and use them for lighting in the final fragment shader. If you pass a matrix uniform to this pass, that translates from world space to screen space of the light pass, you can calculate your shadow texcoords. So

Re: [osg-users] singleton instane

Hi David, Thanks for the suggestion of the singleton design . I tried to design a template base class as follows : Code: namespace osgOpenCL { /** This class helps to build the singleton design pattern. Here you have full control over construction and deconstruction of the object.
