overlapBounds()

bool overlapBounds ( const rcReal *  amin, const rcReal *  amax, const rcReal *  bmin, const rcReal *  bmax  )

overlapInterval()

bool overlapInterval ( unsigned short  amin, unsigned short  amax, unsigned short  bmin, unsigned short  bmax  )

rcAddSpan()

void rcAddSpan	(	rcContext *	,
		rcHeightfield &	hf,
		const int	x,
		const int	y,
		const rcSpanUInt	smin,
		const rcSpanUInt	smax,
		const unsigned char	area,
		const int	flagMergeThr
	)

The span addition can be set to favor flags. If the span is merged to another span and the new smax is within flagMergeThr units from the existing span, the span flags are merged.

rcAddSpans()

void rcAddSpans	(	rcContext *	ctx,
		rcHeightfield &	hf,
		const int	flagMergeThr,
		const rcSpanCache *	cachedSpans,
		const int	nspans
	)

rcCacheSpans()

void rcCacheSpans	(	rcContext *	ctx,
		rcHeightfield &	hf,
		rcSpanCache *	cachedSpans
	)

rcCountSpans()

int rcCountSpans	(	rcContext *	ctx,
		rcHeightfield &	hf
	)

rcRasterizeTriangle()

void rcRasterizeTriangle	(	rcContext *	ctx,
		const rcReal *	v0,
		const rcReal *	v1,
		const rcReal *	v2,
		const unsigned char	area,
		rcHeightfield &	solid,
		const int	flagMergeThr,
		const int	rasterizationFlags,
		const int *	rasterizationMasks
	)

No spans will be added if the triangle does not overlap the heightfield grid.

		const rcReal *	verts,
		const int	nv,
		const int *	tris,
		const unsigned char *	areas,
		const int	nt,
		rcHeightfield &	solid,
		const int	flagMergeThr,
		const int	rasterizationFlags,
		const int *	rasterizationMasks,
		const rcReal *	vertsbmin,
		const rcReal *	vertsbmax
	)

Spans will only be added for triangles that overlap the heightfield grid.
