fill_raw_noise8()

void fill_raw_noise8	(	uint8_t *	pData,
		uint8_t	num_points,
		uint8_t	octaves,
		uint16_t	x,
		int	scalex,
		uint16_t	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
