# BuddhabrotCL

- Multicore OpenCL rendering with fast Metropolis-Hastings kernel.

- Tested on Intel OpenCL 1.2, NVidia OpenCL 1.2 CUDA 8.

- Open source kernels: buddhabrot, anti-brot, mandelbrot, julia, newton, kaliset. You can write your own and run it.

- Rendering huge images, up to 120Mpx, about 11000x11000px image size.

- A lot of parameters.

- Selectable regions and zoom.

- RNG inside OpenCL kernel. Tausworthe random number generator by L'Ecuyer.

- HDR image filters: linear, sqrt, log, ln, exp.

- Image tint, exposure, visual parameters.

- Interpolation of the orbits (just for fun in early versions <= 1.8.4): linear, cosine, bicubic.
