Regarding the opTRS - that's weird with no matching overloaded function, but you can try working around it by commenting line 420 of DEF-Terrain

// Global transformations
// z = opTRS(z, TerPTTranslate, TerPTRotate, TerPTScale);


You can also replace the space-transform file with the one attached.




That worked for me!!!  afro embarrass cheesy

Hmmm, did you try it's really faster? Sqrt is a though one too.
 2 sqrt vs. 4 trig functions?  According to what I've read it's faster...  and.. well,  according to what I've experienced.

  Pine Tree with trig takes about 2 times as long as the algebraic pine tree.  sooo...

lol at myself wink I didn't mean that last comment to sound so snarky, sorry 'bout that.
My hope is that it does work, the images you've presented look really good.

opTRS is declared in Space-Transforms.frag as vec3 opTRS(vec3 , float , vec3 , vec3 )
                          and called in DEF-Terrain_v3.frag as opTRS(vec3 , vec3 , vec3 , float )

it needs to be called the same way it is declared wink

I am curious what this is used for?
Code:
// http://www.fractalforums.com/fragmentarium/fractal-plus-change-of-domain-mashup/
// performs the active c = T(s)
vec3 domainMap(vec3 c, vec3 invC){
float s = dot(c,c);
return c/s + invC;
}

→ I posted a corrected file version a few posts above.

Code:
// http://www.fractalforums.com/fragmentarium/fractal-plus-change-of-domain-mashup/
// performs the active c = T(s)
vec3 domainMap(vec3 c, vec3 invC){
float s = dot(c,c);
return c/s + invC;
}

It's used by some fractals and as I said the code I posted is a part of a larger thing I have, so not every bit is used.

Here's a quick RnD workinprogress test done with the generator.
How you guys like it?

Patryk Kizny, I am new to this, my questions is how can I try out this Adavanced Terrain Generator, is it a standalone software or plugin within another tool? I didn't find any downloadable link, Thanks!

@Patryk Kizny can it be refined down to just the terrain generator and default DE-Raytracer.frag  huh?

Thank you guys!  wink

Crist, but that wasn't rendered with my script?
Because it's don't work  cry I have the same problems as sayed before. Too long comlilation... and error. So today i opened your code and got only your noise functions (n1,n2,n3,n4) and i runed it in course. Full script too hard.
Maybe if you have some time, could you set default values in sliders to most-faster-mode  huh?  Thank you.
