Method Detail

getBitSet

public final java.util.BitSet getBitSet()

Specified by:

getBitSet in interface BSPVisibilityUpdater

setPVSUsage

public void setPVSUsage(boolean enabled)

Enables or disables PVS usage.

Parameters:

enabled - if true the PVS is used to disable hidden geometry, false and everything is enabled

isPVSUsed

public boolean isPVSUsed()

Returns:

true, if the PVS is used to disable hidden geometry. false, and everything is enabled

updateVisibility

public boolean updateVisibility(org.openmali.vecmath2.Matrix4f cameraTransform)

Disables geometry that is invisible according to the PVS

Specified by:

updateVisibility in interface BSPVisibilityUpdater

Parameters:

camPos - the position of the camera

Returns:

true, if PVS has changed.
