Ok cool. I'll try the new version when I am back home.

By the way, does moving local variable declarations outside a loop make the script run any faster?

I do not think that you will get a noticeable effect out of that.

Also, there are some nice Lua profiling tools out there, I've been using LuaProfiler to optimize a raytracer engine and the output is very useful. Possible you can use one at PC side.

One thing that helped with 3D in the past on the Nspire was switching to fixed points or integers instead of floating points. This is partly why Crafti runs over 3 times faster than Ncraft despite having not only textures, but also greater rendering distance. But I don't know if those are available in Nspire Lua.

Ha, that looks reeeally cool

Hope you can find a way to speed it up a bit hahaha.

In Lua number type is a compile time option, and most versions are built to use floats/doubles. So sadly there is no way to force pure integer usage (as far as I know).

Ah, too bad. I wish this was possible in Basic and Lua. Maybe the render distance and quality could be reduced to increase the frame rate? But I wonder how much quality reduction would be required in order to reach 3 FPS?
