Hi, My schedule lightened up a bit... I have an extra 24 hours to work on my osg/cuda problem, so I would like to incorporate CUDA into osg the "correct" way, which I think may be osgCUDA.
Here's what I am currently doing Step 1 App renders scene to a FLOAT texture via a FBO/RTT camera Step 2 This texture is used as input to a shader on a second pass/RTT camera. The shader does some calibration stuff then renders it to a full screen quad. Step 3 Final render pass renders quad from step 2. Here's what I NEED to do... Step 1.5 Pass texture from Step 1 to a cuda kernel for processing before the calibration pass (Step 2) Questions: 1. Is this something I can use osgCUDA to do? 2. Would it be similar to the osgTexDemo? 3. Can I use an FBO, or do I have to switch to a PBO RTT? CUDA 4.0 is not necessary but would be cool as I have to use it eventually, but to get past this proof of principal step I can use 3.2... or 2.3... CD Thank you!
