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

Some really great landcapes, Crist-JRoger! And great to see that the Fragmentarium groups are so active :-)

I glanced at the code- your bump test frag doesn't include anything to add the heightmaps to the DE of the fractal.

  You have to incorporate the information provided by the "textureIT(...,...);" function call into the calculation somehow.  In addition, it's not really set up correctly.  Got to take care of some stuff though, so will be a bit before I get to it, I'd suggest looking at my working code and figuring out the information flow pattern.

Regarding the render artifacts you had on texturing - I bet this is the same thing I had issues with - not sure which thread was that, but as 3dickulus pointed, that was something related to MIPMAPS and texture settings. I think I had these problems with Synthclipse, but they looked identical. You'll find it in recent Frag threads or in Synthclipse forum.

  Hmm, I thought you meant heightmapping by "texturing".  That's pretty weird.  I put out a working coloring texture version of DE-Kn2 (should be in this or the "help!!!" thread) somewhere around here.


  Problem with checking your code is my GPU is pretty slow and it takes about a minute to compile anything with DE-Kn2, so I don't like messing around with that code branch now.  It usually takes a whole bunch of compiles to get something good enough for release, and a whole bunch of waiting a whole minute when other people have GPUs that compile in 1/100th the time it takes for me to compile?  Nahgonnahappen.

  I should eventually have a faster GPU so that I can accomplish more... but that's the future. 

I did'n find anything about height-mapping artifacts 

It does not depend on the scale, most of the brightness differences
