Triangle Slicing

  By code, openGL

Thanks to a java/firefox crash combo, i lost the article i was writing. So here’s a shortened version without all the explanation (i’ll write them later).

Last week, I came across a paper called “Generic Mesh Refinement on GPU” and decided to implement it. I finished the refinement pattern generation and the use of a vertex shader to display the refined mesh today.
Here are the results:

1 2
Level 1 refinement Level 2 refinement
4 8
Level 4 refinement Level 8 refinement

As my main goal is to use this technique for displacement mapping, i modify each point in order to map a sphere:

1 2
Level 1 refinement Level 2 refinement (sphere)
4 8
Level 4 refinement (sphere) Level 8 refinement (sphere)

Attack of the giant snake!

  By code

Giant evil snake I’m currently playing with python and gtk. I’m trying to do a homemade package creator. The interface was made with glade, the gtk/gnome interface builder. It’s pretty easy to use. I managed to make a decent interface in about 5 minutes and here’s the result :

Pak interface

Unfortunately, glade can only generate C/C++ code. I searched the web for some way to create python code from glade files and i found something called Kefir.
All i had to do was to call :

python kefir.py myfile.glade

And all the interface code was generated. I now “only” need to code the core of the application. If you want to create pygtk applications under windows, you’ll need to install :

  • Glade and gtk (Gaim users please take care before installing gtk 2.8.x. You won’t be able to connect)
  • PyGtk
  • Python 🙂

I tried Py2exe in order to create an executable out of the python source. I created some basic setup file (mostly ripped from Py2exe documentation and this tutorial). Then i typed :

python setup.py py2exe

Shazam! A directory containing all the required dlls and files was created.

Next step : start coding !
