fill_raw_noise8()

void fill_raw_noise8	(	fl::u8 *	pData,
		fl::u8	num_points,
		fl::u8	octaves,
		fl::u16	x,
		int	scalex,
		fl::u16	time )

Fill a 1D 8-bit buffer with noise, using inoise8()

Parameters

pData	the array of data to fill with noise values
num_points	the number of points of noise to compute
octaves	the number of octaves to use for noise. More octaves = more noise.
x	x-axis coordinate on noise map (1D)
scalex	the scale (distance) between x points when filling in noise
time	the time position for the noise field
