Re: [osg-users] OpenSceneGraph-3.3.3 developer release

Hi Robert, Attached is a link[1] to the database build with the current trunk of OSG and VPB. It works as intended with the trunk osgviewer. However, I think I just found the next issue :-( I cannot use vpbmaster anymore for compiling. It gets stuck after adding all tasks (I've waited a fair

[osg-users] Some thoughts on the new DisplacementMapping technique

Hi Robert, after inspecting the new DisplacementMappingTechnique I have some ideas. First of all, the shader source code should be configurable from the outside via interface in order to integrate it into own pipelines (in my case I have a CustomShaderProgram based pipeline. Another option

Re: [osg-users] OpenSceneGraph-3.3.3 developer release

Hi again, I've identified one crash in the GLBufferObject::bindBuffer due to an uninitialized _extension member. It seems, it gets destroyed somewhere in the middle. Unfortunately the GLExtensions object doesn't have a declared destructor, so chasing this down is harder than I thought. I'll

Re: [osg-users] OpenSceneGraph-3.3.3 developer release

Hi Robert, as already written, the problem is an invalidated _extensions object. It seems to be invalidated by the State destructor, which causes the destructor of the GLExtensions object to be called. (I've got there using a memory breakpoint) I've attached a callstack for analysis. (i've

Re: [osg-users] Low frame rate ( Update Callback on 50 bones ).

Hi Chris, Did you simply try to do nothing in the callback? Maybe the callback is called to often per frame. Also I've sort of lost track how you apply the matrices to your boned model. If you are using visitors to retrieve the bones in the callback, it might be simply to slow. I would use
