BoundingSphere

public BoundingSphere(AbstractMesh mesh)

Method Detail

getMeshHeight

public float getMeshHeight()

Description copied from interface: BoundingVolumeIface

Returns the height of the mesh that is bounded by the bounding volume.

Specified by:

getMeshHeight in interface BoundingVolumeIface

Returns:

height of the mesh

getCenter

public Point3D getCenter()

Description copied from interface: BoundingVolumeIface

Returns the center point of the bounding volume

Specified by:

getCenter in interface BoundingVolumeIface

Returns:

center point of the bounding volume

getRadius

public float getRadius()

Returns the radius of the sphere.

Returns:

radius of the sphere

isWithinFrustum

public boolean isWithinFrustum(ViewingFrustum frustum)

Description copied from interface: BoundingVolumeIface

Determines whether the bounding volume is inside the viewing frustum. If it's not inside the viewing frustum the mesh that is bounded by this bounding volume doesn't need to be drawn anymore.

Specified by:

isWithinFrustum in interface BoundingVolumeIface

Parameters:

frustum - viewing frustum object which is coupled to the camera object

draw

public void draw(javax.media.opengl.GL gl)

Description copied from interface: BoundingVolumeIface

Draws the bounding volume

Specified by:

draw in interface BoundingVolumeIface
