	)		const

Loads bbox.

Parameters

time	Cache frame, this is must always be a value between the prev, current and next frame. You should load the correct frames before calling this function
box	BBox loaded

loadFrame()

void Atoms::AtomsClothCache::loadFrame

(

int

frame

)

Loads a cache frame and stores the current frame data.

If a frame was already loaded then the old frame data is moved to the previous frame slot

openCache() [1/2]

bool Atoms::AtomsClothCache::openCache	(	const std::string &	cachePath,
		const std::string &	cacheName
	)

Opens a cache.

Only the header is loaded

		const std::string &	cacheName,
		const std::vector< int > &	agents
	)

Opens a cache.

Only the header is loaded

Parameters

agents

Agents ids, it loads only those agents from the cache
