[osg-users] Using another threading library with osg's openthreads?

As a general question, expecting a general or specific answer, I'd like to know if it is efficient to use another threading library like OpenMP or TBB on top of OSG's threading? I'm asking because openthreads and tbb would be using their own thread pools, so when it comes to getting hardware th

[osg-users] osg::PPU , Texture unit associated with depth buffer

Hello In osgppu_ssao project in simple.h file, there are the following lines: shader->add("originalDepthTexture", osg::Uniform::SAMPLER_2D); shader->set("originalDepthTexture", 1); Where is the depth texture associated with texture unit 1 ? i couldnt find it anywhere. thnx.

[osg-users] Backward compatibility with custom serializers

Hi, I recently added serialization support for a custom osg::Object derived class in my application. I saved the object to a osgt and osgb file and attempted to load it into an older version of my application, which didn't have serialization support for my custom object yet. Loading the osgt file

Hello. I am working on osgPPU but there are some things i haven't completely understood yet. I add 2 children in root's group. A cow model and the osgPPU::Processor. In processor i have added 1 child which outputs the depth buffer and under that child i have added 1 child which outputs to frame b

Re: [osg-users] Bug in Qt thread integration

Hi, Thanks for the replies and suggestions. I think I might not have explained the issue as well as I thought, so I'll try again. QThread::currentThread does return a value with static type QThread*. However, it might not point to a QThread instance, but an instance of a subclass of QThread.

Re: [osg-users] OpenGL 3.2 support in OS X 10.7 (Lion)

Hi Craig -- as far as I know, no one is using vertex array objects with OSG. I am using OSG built for GL3 in an external OpenGL 3/4 project, but for file loading only, not for rendering. (The external project requires OSG built for GL3 in order to avoid including both gl.h and gl3.h in the same

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 setVerte

Re: [osg-users] OpenGL 3.2 support in OS X 10.7 (Lion)

Robert, Paul, et. al: Has any further discussion or work gone into adding proper VAO support to OSG? I'm interested in contributing if I can, mostly because I'd like to see full 3.2 support for OS X. Craig On Mon, Mar 5, 2012 at 8:22 AM, Robert Osfield wrote: > Hi David, > > On 4 March 2012 20:

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);

[osg-users] bumpmapping and tangentspacegenerator, generating tangents

Dear OSG users, I am trying to develop bump mapping using opengl es 2.0 and openscenegraph. I can't use osgFX because of opengl es 2.0. I have to apply a bump map to an obj that has the map embedded in the MTL. The mtl is like this: newmtl Nuovo Kd 0.80 0.80 0.80 illum 2 Ns 50.78125

Re: [osg-users] dynamic multithreading problem

Hi, I think the problem maybe located in my custom Drawable class. It draws text geometry instead of textured quads (like in osgText::Test). It basicaly works like Group with multiple transforms and geodes with character geometry. But I really need it to be Drawable (structure of transform will

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 o
