Interface StageVisitor

public interface StageVisitor

Visitor interface that can be used to traverse all nodes currently on the stage. Nodes are visited in the order in which they should be drawn, with parent nodes visited before their children. The renderer uses this interface to draw the graphics on stage after each frame update.

Method Details

prepareStage

void prepareStage(Stage stage)

Prepares visiting the stage. This method is called before any of the stage's graphics are visited. It can be used to add initialization logic that should be performed before any graphics can be drawn.

shouldVisitAllNodes

boolean shouldVisitAllNodes()

Indicates whether this visitor should visit all graphics, or only graphics that are currently visible.

visitContainer

void visitContainer(Container container,
 Transform globalTransform)

drawBackground

void drawBackground(ColorRGB color)

drawSprite

void drawSprite(Sprite sprite,
 Transform globalTransform)

drawLine

void drawLine(Primitive graphic,
 Line line,
 Transform globalTransform)

drawSegmentedLine

void drawSegmentedLine(Primitive graphic,
 SegmentedLine line,
 Transform globalTransform)

drawRect

void drawRect(Primitive graphic,
 Rect rect,
 Transform globalTransform)

drawCircle

void drawCircle(Primitive graphic,
 Circle circle,
 Transform globalTransform)

drawPolygon

void drawPolygon(Primitive graphic,
 Polygon polygon,
 Transform globalTransform)

drawText

void drawText(Text text,
 Transform globalTransform)

finalize2D

default void finalize2D(Stage stage)

Called after all 2D nodes on the stage have been visited. This is an optional method, the default implementation is empty.

visitGroup

void visitGroup(Group group,
 Transform3D globalTransform)

drawMesh

void drawMesh(Mesh mesh,
 Transform3D globalTransform)

drawLight

void drawLight(Light light,
 Transform3D globalTransform)

finalize3D

default void finalize3D(Stage stage)

Called after all 3D nodes on the stage have been visited, but before the 2D nodes are visited. This allows renders that support both 2D and 3D graphics to switch from rendering 3D graphics to rendering 2D graphics. This is an optional method, the default implementation is empty.
