Some classic set with dIFS formulas, like amazingIFS, NewMenger2IFS and HeightMapIFS. Mandelbulb 3D, mcrender.
Fractal digital Artwork done with Mandelbulber2 2.15-alpha3.
A slow CPU render with normal ambient lighting.
Here’s a KaleidoscopicIFS render done with openCL using the Monte Carlo Global illumination feature. I tried to keep a low DOF (depth of field) and use of simple materials in order to keep all clean and fast to render.
It took around 35 mins to render at 2K and nearly 3 hours at 4K resolution.
mandelbulber openCL: 30.720 px × 17.280 px = 530.841.600 px
Be careful opening this very large render!
