This is some rad stuff!

Comment on Fragmentarium FAQ by Mikael Hvidtfeldt Christensen

Hi Brynn,

I’m afraid that besides the website, the only way to learn Fragmentarium is by experimenting with the examples. There is a forum at Fractal Forums, where you may ask questions: http://www.fractalforums.com/fragmentarium/, but other than that there is not much help to get.

Regards, Mikael.

First off – Fun program mate! Great work!

The terrain demo is neat. With a little tweaking to the parameters and a reflection hack and added functionality for setting the offset to ‘time’ you can have a basic ocean shader.

Thanks, Andrew. And the link should work now

Fantastic rendering (as always ). I particularly like the look of the 24 cell with its atom-like resemblance.

PS: The ‘this thread’ link appears to be broken.

Thanks, Knighty and Subblue.

I don’t think my raytracer necessarily need to be more sophisticated: I’m not aiming for photorealism – what I hope to achieve is something more dreamy, with strong contrasts and shadows. But I will try out some different techniques, and see what works.

Wow! they look as photography. Are you planning to do bidirectional path tracing?

Comment on Plotting High-frequency Functions Using a GPU. by Mikael Hvidtfeldt Christensen

Hi Pixelmager, very interesting to use distance estimation to plot graphs, but I don’t get very good results? Have you tried it yourself for high-frequency functions (e.g. sin(1.0/tan(x)) ) – I get some terrible artifacts. Perhaps I made a stupid coding error some place…

Those renders are starting to look super real now, great stuff!
