Engine Troubles over Tentacle Planet, part 3

I have made very little progress since the last report, mainly due to the little time that was available to me. Only two things were done:

1. The source code was cleaned up a little.
2. A windows binary was made (OpenGL only).

In the short term I will not work on ETOTP anymore but perhaps for ILGE 2011 or another challenge or expo I'll continue where I left off.

• Making wrapper functions in C for Ogre's C++ methods and adding them to ECL from C using ECL's API. I used this approach because the inverse (making the C wrapper code from Lisp) gave me segmentation faults and didn't get me very far about 2 years ago. (Note: this was using ECL functionality, not CFFI for which there's Okra.)
• Compiling a C program on both Linux and Windows that was (dynamically) linked to ECL, Ogre and OIS. This C program can, for example, start a game right away and quit back to the OS but it can also provide a CL REPL (like ECL's si:toplevel) so one can interactively play with a 3D scene. Since it's just a plain CL one can load extra packages and perhaps start Slime.

• Compiling a statically linked binary on Linux. This didn't go as easily as I had hoped and was starting to eat into my time budget.
• ManualObjects and shadows. I had to resort to Ogre's prefab entities to get shadows working the way I wanted in the time that I had available.

• ECL is a really good option for embedding a CL implementation in C(++) programs. Juanjo has been working on ECL for years now and he's still going strong. Questions on the mailing-list are generally answered within hours.
• One doesn't just add "-static" to a build rule and be done with it :-)
• Perlin noise is usable to animate objects with. Definitely for prototyping since it's so easy and quick to implement.
• I should brush up on my maths.

The source code and the Windows binary are available here http://www.aerique.net/software/etotp/.

I have not given the source code its separate GitHub repository since it will be added to Okra.
