  • Python Success Stories

    Python Success Stories Background MayaVi is an open source scientific data visualization tool written entirely in Python. I started work on MayaVi in 2000. At that time, a few colleagues of mine needed to visualize their computational fluid dynamics (CFD) data but the only suitable tools available were commercial, closed source programs that were prohibitively expensive. We looked at some open source tools as alternatives. OpenDX had just been released to the public and at that time was har...
