Title: grainy noise Post by: coldwetnoz on January 07, 2014, 05:43:26 AM I've been following tutorials and trying to make fractals with Apophysis 7 and the problem I run into most is the noise and grainy looking areas. Is there a way to work on that problem and sharpen up the image? If I'm asking for the impossible, just tell me. :-\
Oops, I did have another question: Why is it that when I follow a tutorial step by step and then looking at their editor, the triangles are not in the same place as mine?...even though I've used their settings? What should I do, leave them like they are or try to line mine up to match theirs? Thanks pslane Title: Re: grainy noise Post by: tatasz on January 07, 2014, 06:33:12 AM I've been following tutorials and trying to make fractals with Apophysis 7 and the problem I run into most is the noise and grainy looking areas.

Thanks pslane Hmm as a random suggestion, drop on http://chat.deviantart.com/chat/aposhack someday, lots of great fractal artists around. The noisy and grainy areas, in general, can be fixed with longer rendering (like setting some higher density... I usually use 10k +, and seen people using up to 30k). If a tutorial gives exact numbers, your editor should be identical to the one in the tuto. Make sure you used the correct settings since, depending of the tutorial, a small shift may ruin it all.

Title: Re: grainy noise Post by: tatasz on January 07, 2014, 05:55:01 PM Hmmm, then it can be something param related (either requires insanely high density to smooth out or it is just noisy - for example this one, http://tatasz.deviantart.com/art/Mechanical-Flowers-359354846, pretty much no matter how long i render it, will have noise). Imaging could probably decrease it... But well, pretty hard to say without seeing. |
