Types

type Vis 

type Vis struct {
	// NumClusters is number of computed cluster
	NumClusters int32
	// ByteOffset contains offsets for cluster pvs and pas
	// Slice length = NumClusters [0]=offset to PVS bit array for cluster
	ByteOffset [][2]int32
	// BitVectors are compressed bit vectors, contains run-length compression PVS data
	BitVectors []byte
}

Vis contains visibility data for clusters Includes both PVS (Potential Visible Set) and PAS (Potential Audible Set)

func (vis *Vis) GetPVSForCluster(clusterId int16) []bool

GetPVSForCluster decompresses vis data for a given cluster see https://developer.valvesoftware.com/wiki/Source_BSP_File_Format#Visibility for more

func (*Vis) GetVisibleClusters 

func (vis *Vis) GetVisibleClusters(clusterId int16) (visibleClusters []int16)

GetVisibleClusters returns all visible clusters ids for a given cluster
