lol, omni-pony and cemetech pony.
Did you show it the guys on cemetech?

Take a look here: http://www.codeproject.com/Articles/570700/SquareplusRootplusalgorithmplusforplusC

It's more complex, but I think it will be faster (better algorithm).

Bump,

nRC_loadBMP now automatically detects and handles :

• 1-bit monochrome bitmaps (B/W)
• 4-bits grayscales bitmaps (16 colours)
• 16-bits R5G6B5 bitmaps (65,536 colours)
• 24-bits R8G8B8 bitmaps (16,777,216 colours, but they are scaled down to the Nspire screen, so either 16 or 65,536 colours)

They're the most common types of bitmaps :) I planned the support for paletted bitmaps for later, since it's pretty complicated.

Also, I added some constants to make porting the engine easier, so this should make your life easier Spenceboy98 :)

Also, the new build of the demo now uses relative paths, so you just have to put textures.bmp.tns in the same directory ;D

I also formatted the whole directory in a logical way x) documentation will be included in the next release (I hope :P)

EDIT : of course, if you have any wish for this engine, please share your ideas, I'll be happy to add them to my TODO list :)

The screenshot looks cool, but the CX one isn't working. It only shows four black squares at the top of the screen.

Edit: Oh, and you should probably clear the screen at the start of your program, the garbage it displays before starting is a bit ugly

Oh you're using it. So I know why there are those vertical lines on the texture : you're trying to use 3-bytes bitmaps but my function only loads correctly 16-bits non-paletted bitmaps.

EDIT : error spotted. You must not cast to unsigned when calculating distance and angle, because pixels at the left of te center have negative angles.
