Re: [osg-users] Passing node transformations to the vertex shader

I've encountered the same problem, and setting the context-getState()-setUseModelViewAndProjectionUniforms(true); for each context didn't work in any case (with a multi-pass offscreen rendering). So the simple solution for me was to use the #version 150 compatibility profile, which let's you

Re: [osg-users] Passing node transformations to the vertex shader

J-S, Thanks for the reply. I hadn't sat down and compared matrices yet, but I had debugged to ensure I was getting something. And yes, I'm accommodating for the fact that it's a ModelView (and not just a Model) matrix. I've also been using the osg_ attributes to this point, in lieu of the

Re: [osg-users] Passing node transformations to the vertex shader

Hi Joel, So far as your optimization tip goes, I assume you're meaning to apply the shader at the transform node as well? I've been doing that sort of thing already, just not on my Transform nodes... No, I mean that all non-Transform children under a Transform will have the same

Re: [osg-users] Passing node transformations to the vertex shader

J-S, Of course. It's not that I didn't know state is inherited by child nodes, but for some reason, my testing of uniform inheritance failed, so I was manually propagating uniform pointers... Took 30 seconds to disable that code and prove your point. Thanks again. - Joel

[osg-users] Passing node transformations to the vertex shader

Hi, I'm implementing shaders in GLSL 140+ (i.e. no built-in uniforms), and I've had reasonably good success thus far. However, it's quite obvious that passing the vertices in using osg_Vertex doesn't include any transformations which may have been inherited (or directly applied). This exact

Re: [osg-users] Passing node transformations to the vertex shader

Hello Joel, It seems apparent that I need to multiply the osg_Vertex vector in my vertex shader with the model matrix for that geometry (via a uniform updated every frame, or at least whenever the geometry is transformed). The only function that I've found that may get the model matrix is

Re: [osg-users] Passing node transformations to the vertex shader

Hey, thanks for the fast response... What you're suggesting I actually tried. The View matrix was intact, but the transformations were not. So far as I can tell, my understanding matches what you're telling me, but just to be sure, I've assumed the following: 1. The CullVisitor function,
