buddhabrotcl's Introduction

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.

buddhabrotcl's Issues

Could Use Some Helping Getting Started

I have no experience using this kind of thing and have no idea what I am doing but really want to learn how to use this software.

I've got a decent Windows laptop and should be able to run this, but after downloading the zip and looking at the contents, it might as well be in Chinese because I have absolutely no idea what to do with this stuff.

Please if someone could give me a detailed step-by-step it would mean a lot to me, thank you!

Higher Color Depth Export

Currently, the program only exports 8-Bit (Per Channel) PNG files along with whatever else the render state is. It would be nice to have a different export option like a 16-Bit (Per Channel) PNG, or ideally a 32-Bit (Per Channel) Floating-Point OpenEXR file. OpenEXR is the best option since it natively supports floating point numbers without any of the weirdly supported TIFF 32-Bit (Per-Channel) mess. It would allow better editing in programs like GIMP afterwards.
