Software

  • VTK: The Visualization Toolkit
  • Free - open source - C++
  • Available at http://www.vtk.org
  • Easy to install (ymmv)
  • Very large user community, active mailing list
  • For the class
  • Supports multiple languages: Python, Java, C++, Tcl/Tk
  • Manipulation of existing modules (pipeline)

VTK Installation @ Home

  • Linux / Mac: from binary or with CMake
  • On Windows with Visual Studio:
  • Obtain Visual Studio for free from www.cs.purdue.edu/msdn/
  • Follow instructions at http://vtkblog.blogspot.com/2007/04/

VTK Installation

  • Linux / Mac: from binary or with CMake
  • On Windows with Visual Studio:
  • First-hand advice from TA:

“Just follow the directions from the first link on that webpage.

  • During the CMake step, I got errors in reference to CMAKE_WORDS_BIGENDIAN not being defined. This was

fixed by clicking the "add entry" button and manually adding CMAKE_WORDS_BIGENDIAN and setting its value to false (for Windows machines).

  • While building I got an error in file "SystemTools.cxx" saying "strdup" was not defined. Replace all instances of

"strdup" with "_strdup".

  • In the instructions, it says when you select the ALL_BUILD project and then select Build you need to wait "a couple
  • f minutes". It takes much, much longer than that.
  • After all of the build steps are completed, you should be able to compile he sample provided on the webpage (the

2nd link). Use that project as a base project for assignments in the class.

  • I compiled VTK in Debug mode. When I tried the example project in Release

mode, it would not run. But did run in Debug mode. I recompiled VTK, but in Release mode. As expected, the example would now only run in Release mode.”
