A realtime mandelbrot renderer, written in C++11 with SDL2, OpenGL and OpenCL.
double precision support, just uncomment the following in CMakeLists.txt
#add_definitions( -DUSE_DOUBLE )The renderer renders the Mandelbrot Set with continuously new samples for nice Antialiasing. A tent filter with a combined Tausworthe and Linear Congruential Generator random generator was used for achieving this. This kind of 'overkill' feature is build in since the main goal is a realtime Pathtracer.
There is also an alternative Mandelbrot implementation and a Julia Set in the opencl file just adjust this line to either 'julia_set' or 'mandelbrot_alt' in GLMain.cpp
