Re: [osg-users] VBO and vertex attribute data

Hi Janna, can you provide the bits of your code where you setup the attributes in the c++ code and the GLSL part where you access it? I've been using this feature for tangent-space attributes like forever and it simply works. The only thing to keep in mind is the slot numbers and names you

Re: [osg-users] VBO and vertex attribute data

Hi Sebastian, I set the vertex attribute array this way: Code: geometry-setVertexAttribArray(s_attributeIndex, m_vertexAttributes.get()); geometry-setVertexAttribBinding(s_attributeIndex, osg::Geometry::BIND_PER_VERTEX); geometry-setVertexAttribNormalize(s_attributeIndex, GL_FALSE); and

Re: [osg-users] VBO and vertex attribute data

Btw I am using osg 2.8.3-4, not sure if it could make any difference -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50412#50412 ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] VBO and vertex attribute data

Ok I think it is working now with eometry-getVertexAttribArray(s_attributeIndex)-dirty(); Thank you :) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50413#50413 ___ osg-users mailing list

Re: [osg-users] VBO and vertex attribute data

Hello Janna, If you use a shader program you'll have to bind the attributes to the program: const std::string name=v_tangent program-addBindAttribLocation(name, index); Then in the vertex shader you can access the attribute via: attribute vec3 v_tangent; hth Sebastian Hi, I am working on

Re: [osg-users] VBO and vertex attribute data

This is being done and as I mention it works fine unless I try to use vertex buffer object. so lets say code like this works: Code: geometry-setVertexAttribArray(s_attributeIndex, m_vertexAttributes.get()); geometry-setVertexAttribBinding(s_attributeIndex, osg::Geometry::BIND_PER_VERTEX);

Re: [osg-users] VBO and vertex attribute data

Hi, I've tried to use gl_MultiTexCoord1 and do geometry-setTexCoordArray(1, secondTexCoords); instead of custom vertex attributes to pass my data and it seems to be working. Does anyone know if there is some kind of problem with using custom vertex attributes ( using methods like
