Re: [osg-users] Which GPGPU postprocessing method is best for me?

I went back to the osgCompute src to look at how it creates a CUDA context. I am tempted to simply use osgCompute since they have an RTT example that looks like it would work for my purposes. The only thing that's keeping me from investing into osgCompute is that the osgCompute forum only has

Thanks Wang Rui, I had a look at the effectscompositor code but I wanted to start with something simpler at first so I went to your cookbook. I followed the NVG example from chapter 6 of your cookbook in order to create a render to texture camera to write the scene to, then a hud camera to

Thank you Jeremy I'll have a look at that implementation (I was actually just reading through Rui Wang's cookbook when you posted this). In the meantime I'll also try compiling osgPPU and osgCompute and go through some examples to assess which of these can accomplish what I am looking to do.

Hi Ethan, You may found the osgeffectcompositor in osgRecipes project as Jeremy says. I'm currently working on a better version of ViewDependentShadowMap and will try to provide a complete pipeline using forward shadows and deferred shading work. It is always appreciated if you and others could

Hello all, I have an osg project that uses shaders to write float32 values representing temperatures to my framebuffer texture. I would like insert a CUDA or OpenCL kernel to take those temperature values in the framebuffer and reinterpret them as colors based on various sensor effects. My
