Not now, I'm busy with some other, more important projects and also other parts of my life.
It's open source and the code should be quite easy to understand, though.

Is there any way to get only the source for nGL and not crafti? I'd like to fiddle with it sometimes.

There's not a seperate repository for it, but you can copy the nGL files from https://github.com/Vogtinator/crafti.
The core files are:
gl.cpp gl.h triangle.inc.h glconfig.h fix.h fastmath.cpp fastmath.h
For some 2D functionality:
font.cpp font.h texturetools.cpp texturetools.h
And basic 3D stuff:
aabb.cpp aabb.h glbox.cpp glbox.h gldrawable.h

I saw the textures in crafti were a little wonky (maybe for speed reasons), are there any texture routine more accurate?

Depends on what you mean by "wonky". Some inaccuracies are due to the fixed point math.
For obvious reasons it's doing Affine texture mapping, but you don't notice that much while playing.
The problem is, that for every scanline, the X distance is the total length of the line. If you want to do it the "correct" way, the length is sqrt(dx*dx+dz*dz), but doing it every line (or like quake, every 5th or so) is still a whole lot too slow. And I can't use the invsqrt trick, as that only works for floats.

Finally, Crafti gets its ticalc news feature :D http://www.ticalc.org/archives/news/articles/14/148/148684.html

Also I need to check the latest version at one point because I think what I got is an older version.

:w00t: I uploaded the latest version some months ago so this is a real surprise for me.

That's fairly simple, the latest version doesn't have the ugly black gradient with 50% opacity menu.

Oh, I just noticed I didn't change the menu at all in v1.1, the ugly black menu is gone since v1.0. For comparision:

That old menu doesn't look ugly to me, it looks clean and modern. The new one does have more 'feel' to it though.
My projects
 - The Lost Survivors (Unreal Engine) ACTIVE [GameCommandoSquad main project]
 - Oxo, with single-calc multiplayer and AI (axe) RELEASED (screenshot) (topic)
 - An android version of oxo (java)  ACTIVE
 - A 3D collision detection library (axe) RELEASED! (topic)(screenshot)(more recent screenshot)(screenshot of it being used in a tilemapper)
Spoiler For inactive:
- A first person shooter with a polygon-based 3d engine. (z80, will probably be recoded in axe using GLib) ON HOLD (screenshot)
 - A java MORPG. (pc) DEEP COMA(read more)(screenshot)
 - a minecraft game in axe DEAD (source code available)
 - a 3D racing game (axe) ON HOLD (outdated screenshot of asm version)

Oh right yeah that menu. I like the new one actually. I thought you meant the items menu at first. :P

Question: is nGL (the library) not on GitHub? I'd really like to use it, after seeing how powerful it is.
