Getting the VTK ("Visualization Tool Kit") on Mac OSX running does not seems to be for the faint-of-heart.

I will follow the "Installing VTK on Mac OS X" from macresearch.org, as it was written in 2007, I'll highlight the differences to a current (August 2010, OSX 10.6) Installation.

CMake CMake can be installed with the following command macports sudo port install cmake

VTK - 1st Try Wondering if you can install VTK also with MacPorts? Wonder not longer, you can't.

VTK - 2nd Try Ok, sometimes following a tutorial is good. Obviously replace export MACOSX_DEPLOYMENT_TARGET=10.4u with your current OSX version (mine is now: 10.6)

Instruction from the TextMate site, this is the minimal info for installing TextMate Bundles
