isActive

public boolean isActive()

Description copied from interface: Drawable

Specified by:

isActive in interface Drawable

Overrides:

isActive in class AbstractDrawable

Returns:

boolean

sphereInFrustum

public boolean sphereInFrustum(Vector3f thePosition,
                               float theRadius)

pointInFrustum

public boolean pointInFrustum(Vector3f thePosition)

pointInFrustumSide

public int pointInFrustumSide(Vector3f thePosition)

sphereInFrustumSide

public int sphereInFrustumSide(Vector3f thePosition,
                               float theRadius)
