noiseRingHSV8()

CHSV fl::noiseRingHSV8	(	float	angle,
		u32	time,
		float	radius = 1.0f )

Generate HSV8 (8-bit) noise for a ring pattern.

Calls noiseRingHSV16() and scales each component down to 8-bit.

Parameters

angle	Position around the ring (radians, 0 to 2π)
time	Animation time parameter
radius	Noise zoom level (level of detail). Larger values = coarser pattern, smaller = more detail (default 1.0)

Returns

HSV8 (CHSV) color with 8-bit components
