Fractal Fun Pictures!

[Thomas]

Felt like some exploring and made some shots (see below). Now I feel the program needs more features though and certainly some better coloring :
However, I will not spend much more time on this program, as I feel (and think most you people here do too) that my time should be focused on Amnesia. Hopefully someone better at math and fractals than I can create a nicer prog!

Thomas is on flames now with this. xD

hi, first of all its super great thx^^ Is there any tweak possibility for multicore systems and or/ i have renderengines like 1HE dualxeons intel servers which i use for rendering fractals and 3d stuff, but they dont have decent graphcards. Any poss to use the engines?
thx a lot

The gpu is what does all the heavy lifting here (cpu is pretty much idle), so there is nothing to gain from using parallel cpus.

Thankyou, thankyou, thankyou Mr Grip!

I'm getting the most amazing images and I've only just started. I'm posting them in my Flickr stream.

You have given us a great gift, good for you.

Here's just a taste :

Edited as the image did not appear last time, or this, and I can't work out how to put the image inline as above :

Fantastic program :

Found a small change in the GL code that that increases the speed quite a lot. Putting the limit test inside the loop will make it drop out after only a few iterations a vast majority of times (it's well worth the extra work when we actually hit something). Then it's possible to reduce the search granularity and still run at a decent frame rate with much greater detail already at the first try.

bool RenderMandelBrot(vec3 avPosition, int alIterations, float afPower)
{
vec3 vTestPos = avPosition;
for(int i=0; i<alIterations; ++i)
{
vTestPos = PolarCoordMulExp(vTestPos,afPower) + avPosition;
if (dot(vTestPos, vTestPos) > 2)
return false;
}
return true;
}

And here's an image from the jungle:


I also tried to increase the number of iterations, but it quickly becomes very grainy and pixelated. I think this is because we reach the limit for the 32-bit float resolution of the GPU. All CPU based programs use 64-bit floats, allowing a lot better resolution. I guess this is what you have to pay for the speed and usability of this program.

Wow, that is the mutant broccoli forest
Really nice pic.

paerl:
Nice one and thanks for the optimization! I did not think that would make that much of a difference since other programs have been slow because of break in loops.

Hello,

have shot pictures in high resolution. So look much better.

[Thomas]

OC_Burner:
WOW!:eek: That sure is high rez!! Excellent!

Please take more at that respolution and try and use fog and such : I would liked to see more zoomed in regions too :

What graphics card are you using?

Also, make sure to use the voxel rendering for the extra detail.
