Class CompileState

java.lang.Object

javax.media.j3d.CompileState

 class CompileState
extends java.lang.Object

The CompileState holds information used during a compile. It is passed to each SceneGraphObject (SGO) during the compile. Each SGO modifies the CompileState as necessary and passes the CompileState to its children (if any). The CompileState currently has two functions: appearance mapping and shape merging. Appearance mapping maintains a list of the unique appearances seen during the compile. getAppearance() is used to turn multiple, equivalent and static appearances into a single shared appearance. The shape mergings collects shapes that are potentially mergable during a compile. The shapes are sorted into a Map of Lists of shapes, using the shape's appearance as the key. After a subtree is traversed, the shapes are merged and added to the Group.

getAppearance

AppearanceRetained getAppearance(AppearanceRetained app)

Returns an unique appearance which equals app. If appearance does not equal any previously found, the appearance will be added to the known appearances and be returned. If the apperance equals a previously known appearance, then the prevously known apperance will be returned

void addShape(Shape3DRetained shape)

printStats

void printStats()

doShapeMerge

void doShapeMerge()

getCompileFlags
