Function Documentation

function animate

(

)

ANIMATION LOOP

function getNewTexture	(		buffer,
			size,
			rgb,
			debug_tex
	)

GENERATES AND RETURNS A NEW TEXTURE WITH: BUFFER = TEXTURE DATA RGB = GL.RGB | GL.RGBA SIZE = (WIDTH == HEIGHT)

			size,
			fill
	)

INITIALIZE ARRAYS

function mhb

(

mhb_data
