Pi as a 3D sculpture
Full Image: http://goo.gl/6XGLUq
I recently wrote a python program in python's IDLE which calculates pi using chudnovsky's formula. Using the output of this the program takes each decimals of pi and translates it into coordinates around the edge of a circle. This is then exported to an .obj file and within Blender smoothing and lighting is added.
This image (The full one : http://goo.gl/6XGLUq) shows pi to 10000 decimals bottom to top, the computation of this, and it being saved to a .obj file, took 24 seconds. Rendering, a bit longer at 2 hours 30 mins, at 1600 samples.
