Hi. I have an RGBAF (specifically, GL_RGBA32F_ARB ) image coming from a custom image provider plugin. The image has components that are greater than 1.0, making it sort of HDR-ish.
This all works great when I glTexSubImage and supply the floating point data myself, and render it with a custom consumer plugin. Yay. Now, I'd like to be able to leverage all of that lovely core image jazz for some image manipulation. The first thing I notice is that my float 32image is now clamped to 0.0 and 1.0. Is there a way to work around QC (and, possibly CI) doing this clamping? Reading this entry online lends me to believe most filters simply do not work with HDR at all. http://naked.la/emperor/2007/11/why-naked-light-doesnt-support-hdr/ Using a custom core image kernel, having an HDR out option would be nice. Thanks for any information. _______________________________________________ Do not post admin requests to the list. They will be ignored.
