Title: Extended Precision Post by: M Benesi on November 14, 2012, 08:27:39 AM I'm thinking about it again. Posting it here to stir stuff up a bit. http://crd-legacy.lbl.gov/~dhbailey/mpdist/ Title: Re: Extended Precision Post by: Syntopia on November 14, 2012, 08:18:40 PM Some parts of the DSFUN90 library are already included with Fragmentarium (emulated double precision): http://blog.hvidtfeldts.net/index.php/2012/07/double-precision-in-opengl-and-webgl/
I used Henry Thaslers' GLSL code, and he has also tried with higher resolution: http://www.thasler.org/blog/?p=143, but unfortunately this slow downs the GPU to the point where the CPU is stronger...

Awesome. I'll check that out- noticed a bit of what I thought was single precision artifacting- layered appearance on zoom in. I'm wondering if there is a way to force change CPU to GPU when timing dictates? Well- phone call with drunk friend. Gotta talk to them for a bit. :D |
