Field Detail

currentMarkedFlag

public static int currentMarkedFlag

bit position = camera id

Constructor Detail

TopoGraphNode

public TopoGraphNode(RenderCell cell)

Method Detail

flagRebuildCoverList

public static void flagRebuildCoverList()

Only relevant to topological depth sort TopologicalSort. Sets a flag which causes the baking of the coverlist. This causes every field wich contains the covered neighbors to be rebuild. Used to prenvent duplicate graph rebuilds in one frame.

inverseMarkedFlag

public static void inverseMarkedFlag(int id)

inverses the dirty flag comparison so everything marked is now unmarked. used to mark the visited obejcts with depthsort.

Parameters:

id -

addCoveredEnts

public void addCoveredEnts(AbstractEntity ent)

adds the entity into a cell for depth sorting

Parameters:

ent -

getCoveredEnts

public java.util.LinkedList<AbstractEntity> getCoveredEnts()

clearCoveredEnts

public void clearCoveredEnts()

getCoveredBlocks

public java.util.LinkedList<TopoGraphNode> getCoveredBlocks(RenderStorage rs)

isMarkedDS

public final boolean isMarkedDS(int cameraId)

Check if it is marked in this frame. Used for depth sorting.

Parameters:

cameraId - camera cameraId

Returns:

See Also:

TopologicalSort.visit(TopoGraphNode)

markAsVisitedDS

public void markAsVisitedDS(int id)

Marks as visited in the depth sorting algorithm.

Parameters:

id - camera id

See Also:

TopologicalSort.visit(TopoGraphNode)

getCell

public RenderCell getCell()

get the represented cell instance

Returns:

setCell

public void setCell(RenderCell cell)

Parameters:

cell -
