Author Topic: CUDA mandelbrot renderer - should I publish?  (Read 5301 times)

I've just finished writing my simple mandelbrot renderer using CUDA and C++. The settings (position, zoom, resolution etc.) can be changed in the mandelbrot.cfg file, and the renderer operates on simple doubles and apparently supports resolutions up to 16k (32k not working, needs more testing). Because of no advanced libraries for deeper numbers, you can't really do deep renders. The program also seems to have problems with zoom values (testing with kalles fraktaler showed differences in zoom). However, the program (in my opinion) makes nice pictures (links in the end of the post).

The key question here is, should I release it?

the colors look great, nice and smooth A Beer Cup please do publish so we can compare notes smiley

I posted a short vid recorded on my desktop here in this topic of my attempt at real time mandelbrot+julia+hybrid on GPU but only to e-14

GARPREC will do arbitrary precision using the GPU to 10,000 digits?
you can find some GPU vs CPU test results here at the bottom of the page.

Resistance is fertile...
You will be illuminated!

I forgot to point out an important thing, specifically...
My renderer isn't realtime, doesn't allow explorations, it only renders to a bitmap and saves it.
