Hi, we've found OSG to be quite useful for image processing type GPGPU work. One can get quite a bit done in OSG with GLSL, multiple passes and multi-target FBOs. jp Robert Osfield wrote: Hi Judie, You wouldn't integrate GPUPU in the same way as SIMD instructions on the CPU for matrix

Hi, Are there any plans for utilizing General Purpose GPU for matrix operations? At SIGGRAPH 2008, there was a lot of discussion about utilizing the GPU this way and some hardware independent libraries for using GPGPU do exist. I am currently looking into this for future projects. Thank you,

Hi Judie, You wouldn't integrate GPUPU in the same way as SIMD instructions on the CPU for matrix operations, rather you'd use it a similar way to present GLSL programs - that you pack the input a large block of data with a program and execute it on the GPU then later get the results. There is
