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.

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...

Socrates, this was meant for the 4D thread, right?

  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
