.. isn't that complex, but requires some installation on Ubuntu.
Here a quick and dirty going-through.

Header Compile Time

Posted on February 4, 2010

Just coming from the Signals/Callback messup I took a short look of compiling (parsing, no instantiation) times of some C++ and Boost Headers I usually have always on.

On my machine (GCC 4.4, x86-64) without any other flags (Optimization did not seem to have a influence). I always took the user-time; no waiting for data or such things.

Beleg Thesis online

Posted on September 30, 2008

Beleg thesis is online and can be found alltogether with the tetrahedral mesh renderer TetraViewer2 here. You can grab the source and build it foryourself; but I cannot release it yet to GPL as the university didn't yet cleared which license they use for their own library. But you shall be free to use it for academical purposes.

Note that GPU GLSL renderer needs a GeForce8 to render properly as it uses integer textures and direct texture access (with integer coordinates) in order to fast access the mesh from a fragment shader.

Some points from the web presentation:

  • 3 Preintegration systems: naive, Bin-Approach from [LWM04], Taylor-Preintegration (currently not working)
  • 3 Rendering approaches: FineDrawer (GPU Raycasting), SingleDrawer (Cell Projection), SoftwareDrawer (Software Raycasting)
  • 2 Tetrahedron sorting approaches needed by SingleDrawer
  • 2 Classification systems
  • TetGen-Importer
  • FLTK2 GUI
  • Self test for preintegration
  • Multithreading support, gaining better performance for preintegration on multi core CPUs
  • Support for Windows, Linux, Mac OSX
