FractalStudio

Cuda accelerated fractal rendering.

Viewer

The viewer is an interactive GUI fractal renderer.

The viewer uses PyTorch cuda vector code to render fractals efficiently with only python.

cd ./viewer

python main.py viewer --alg mandelbrot
python main.py viewer --alg buddhabrot
python main.py viewer --alg nebulabrot

Renderer

This uses native C and Cuda code to render fractals. It is designed to export high quality images, but also includes a live viewer for the mandelbrot.

This is faster than the viewer, but is harder to use.

This is the first version of this project, which can still be found on the old branch.

render/mandelbrot/

Realtime visualization of the mandelbrot set.

cd ./render/mandelbrot

# If you have a CUDA gpu
make cuda
# or use cpu
make cpu

# generate image
python main.py image --width 4096 --height 4096

# use pygame interactively
python main.py live --width 1280 --height 720

# change kernels
python main.py --kernel cpu

Options to main.py:

• mode: image or live.
• --kernel: cpu or cuda to set computing kernel. GPU is usually faster.
• --width: Width of viewing window or generated image.
• --height: Height
• --max-iters: Max iters to simulate function. More iters is slower but more accurate.

render/buddhabrot/

Render the buddhabrot or nebulabrot.

cd ./render/buddhabrot

make cpu

# generate buddhabrot
# Args are [iters] [samples]
./a.out 1000 10000000
python convert.py out.img buddhabrot.png

# generate nebulabrot
# calls a.out, convert.py, nebula.py many times and compiles the final image.
./nebula.sh
