Description copied from interface: ILcdBounded

Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

Specified by:

getMeshes in interface ILcd3DMeshNode

Overrides:

getMeshes in class TLcdOpenFlightNode

Returns:

a list of 3D meshes, possibly empty but never null

accept

public void accept(ALcdOpenFlightSceneVisitor aVisitor)

Description copied from interface: ILcdOpenFlightNode

Accepts an OpenFlight visitor. A typical implementation of this method should call aVisitor.visit(this).

Specified by:

accept in interface ILcdOpenFlightNode

Overrides:

accept in class TLcdOpenFlightTransformableNode

Parameters:

aVisitor - the visitor to accept

getStyleForPrimitive

public ILcd3DMeshStyle getStyleForPrimitive(int aPrimitiveIndex)
