Direct Known Subclasses:

VRMLGridBuilder

public class GridBillboarder
extends Billboarder

This Billboarder render the object slice by slice from the back to the front. After that the camera will rotate 90� to the left and render slice by slice again. And so on, until four sides are rendered. From the top of view, it seems like a grid.

Method Detail

beginAt

public void beginAt(int side,
                    int step)

billboarding

public void billboarding()

Description copied from class: Billboarder

This method rendered each side of an object given in the view. The number of sides was set by invoke the initialize - method. After a render-step the camera will rotate and it will be start the next render-step.

Overrides:

griding

public void griding(int step)

initialize

public void initialize(double distance,
                       double zOfsset,
                       boolean fourSides,
                       int steps)

Sets the camera on initial position. This billboarder creates picture only from two or 4 sides. The parameter steps defined the number of slices has to be create at every side of view. To reach an optimum coverage of all parts of the model only odd numbers of slices will be generated. If an even number is given, this will be reduced by one so the number is odd.

Parameters:

distance - Distance between camera and the origin of the coordinates-system

zOfsset - The z-axis shift of the camera

fourSides - If this is true all 4 sides of the model will be rendered by this. Otherwise only the front and left-side will be rendered.

steps - Odd number of slices for every side of view.

makeAllNames

public void makeAllNames()

makeNames

protected void makeNames(int stopSide,
                         int stopStep)

setLayer

public void setLayer(int visible,
                     int invisible)

Defined which layer is for the visible and which for the invisible objects. The default-value for visible is 0 and invisible 15.

Parameters:

visible - The Number of the visible layer in the 3D-view

invisible - The Number of the invisible layer in the 3D-view

setRunLater

protected void setRunLater()

Description copied from class: Billboarder

When a Billboard-Render-Thread is finished, the implementation of this method will be executed later.
