Method Detail

setShapesTransparency

public static final void setShapesTransparency(Shape3D shape,
                                               float transparency,
                                               boolean allowNullTA)

Sets a Shape3D's transparency.

Parameters:

shape - the Shape3D to manipulate

transparency - <= 0 for not transparent, > 0, <= 1 for transparent

allowNullTA - if true, then the TransparencyAttributes are set to null, if transparency is <= 0

getShapesTransparency

public static final float getShapesTransparency(Shape3D shape)

Parameters:

shape - the Shape3D, which's transparency is to be read

Returns:

a Shape3D's transparency.

setTransparency

public static void setTransparency(Node node,
                                   float transparency)

Sets the transparency of all Shape3Ds in the given Group, recursively or of this node if it's a Shape3D. If you call it on a Node, which isn't either a Shape3D or a NodeGroup, it will just do nothing.

Parameters:

node - The Shape3D/Group to set the Transparency to

transparency - A value in the range [0f-1f], 0f being completely opaque, and 1f completely transparent

mergeShapesTA

public static Group mergeShapesTA(Shape3D... shapes)

mergeShapesITA

public static Group mergeShapesITA(Shape3D... shapes)
