Member Function Documentation

void PatchCacheLine::addPatch	(	int	srcPatch,
		float	formFactor
	)

Add patch to cache-line (and save form factor of pair of patches).

Parameters:

	srcPatch	Source patch from a pair of patches.
	formFactor	Form factor of a pair of patches.

Note:

There is no need to specify destination patch, because destination patch is cache-line specific.

Color PatchCacheLine::totalRadiosity

(

)

Returns:

Return radiosity summarized from all patches saved in cache-line.

This computation respectes cached form factor for each patch.

size_t PatchCacheLine::itemCount

(

)

Return total count of patch saved in cache-line.

static size_t PatchCacheLine::itemSize

(

)

[inline, static]

Return raw allocation size of one cache item.
