END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

A) Thanks, part of the essentials I'll have to get down.  Very pleased with how I've been getting along though and it gets easier and easier with each Aha!  Like finding you can toss ISO formulas at it and click, answer to how all of it works.  Nothing like the clarity you achieve on your own.  "Poke it with a stick!"  Tossed this shape in for it to use last night and this came out. 

   return ((p.x*p.x)-(p.y*p.y)-(p.z*p.z));



C) Alpha 5, that's the one I've got.  I'd like to translate some of the custom formulas in Ver 1.21 over.  Decided that if I wanted total freedom and mastery though, Frag was the way to go.  Learning OpenGL and such has been on my must-do list for a very long time now and I'm just happy to be finally at it.  Coding frenzy, dragged away once in awhile to have food shoved in, naked half the day because I was only going to get up to check that render and then I thought of something so now it's 3:00 pm and....     Joy!
