PySoy, a month after

A bit more than a month of SoC work has passed now, PySoy is alive and getting better day after day, and since some days you can even get a taste of it!
After the release of the GPLv3 our SVN repository has been opened to the public, read more on Arc’s blog.

Textured Pyramid

About the point of view of my application the project is proceeding well and we can show you a textured pyramid at last (as usual I have to thank Arc for the huge help 😉 )! 🙂

I’ve left my normal mapping experiments behind for a moment (after having discovered how to create correct object space normal maps in Blender with the “six colored lights” hack 😀 ), and I’m now working on the lighting system which will represent the base for every non trivial texturing technique.

Much more is yet to come, stay tuned!

My Summer of Code begins with PySoy r44

Summer of Code has started just today (even if currently it is only a “Spring of Code” 😀 ) but a little contribution of mine has already made his way inside the SVN repository of PySoy.

But let’s start from the beginning…
After having shown to Arc an early draft of an UML class diagram for the current code I decided to come back to work on some test code I had written in the afternoon.
It was just a classical spinning cube demo to actually compare PyOpenGL versus Pyrex speed, I don’t report the results here because they are quite identical, if I haven’t done any mistake it should be the absolute minimum complexity of the code which actually determined this result.
Anyway, even without this proof I firmly believe in the power and speed of Pyrex. 😉

Going back to my commit, my changes affected a small yet important area of the code, I think we will remember it in the future. 🙂

In src/windows-glx/soy.windows.pyx:


In include/gl.pxd:

# Constants
  ctypedef enum:
    # glPush/PopAttrib bits

In src/windows-glx/soy.windows.pyx:


Was it better before or now? 😉

Accepted for Summer of Code

Dear Applicant,
Congratulations! This email is being sent to inform you that your
application was accepted to take part in the Summer of Code.

Yeah, one of my two proposals has been accepted!

My first proposal was about working on GL O.B.S. under the Python Software Foundation, unfortunately it was very likely going to be discarded.
I learned this from a mentor who contacted me, he wrote that my application was based on a personal program and that it would have been hard to find someone to mentor me, moreover I wouldn’t have contributed to the Python community. He also added that I could have been a good candidate for his project, he is, indeed, Arc Riley, Project Manager of PySoy.
And so I did, I wrote another application and, this time, it has been accepted. 🙂

My work will be to integrate multi-texturing in the PySoy rendering loop and API, document API additions, test the whole under many different free software drivers and then implement some related techniques, like bump or normal mapping.

I’m really glad of this opportunity, I will learn many interesting OpenGL and Python topics and I will improve my design, teamwork and communication skills.
Thank you Google! 😉
