Hi sholmes, I use GL_RGBA32F in my projects. However, CUDA had problems to map GL_RGBA16F in earlier versions. Maybe you should try to run this internal GL format with our RTT-example first. Cheers, Jens -- Read this topic online here:

I was successfull in using the GLRGBA32F as well as the GL_LUMINANCE_ALPHA32F. Thanks for the feedback. osgCompute is a very interesting project... Would like to see across the board support for multithreaded mode though... Is that in the works? jens.svt wrote: Hi sholmes, I use

I am trying to mod this sample to use the following texture type... Does osgCompute support this? textureRect0-setSourceType(GL_FLOAT); textureRect0-setInternalFormat(GL_RGBA16F_ARB); textureRect0-setSourceFormat(GL_RGBA); jens.svt wrote: Hi serkan, hi J.P., Here is a link to a simple

Hi, First of all thanks for the great work you've benn doing so far. I'm trying to build up a post processing setup using osgCompute but I have some problems. This is how my scene graph looks like: Computation (Render before children) |- Camera (Relative, attached MRT textures and using FBO)

Hi, I've recently been fiddling/debugging with a similar setup, nl RTT to osgCuda. From what I've seen in the code (r314) the copy step is missing for osgCompute::MAP_DEVICE_SOURCE. Allocation of a copy happens, but if the texture does not have an osg::Image, no sync is taking place. Sending
