public abstract class AbstractTile
extends Element

This is the basic class for all Elements which consist of a sequence of 3D colored tiles: Ellipsoid, Cylinder, Box, ... A tile is basically a collection of rectangles. NOT YET FINISHED!!!!!

Method Detail

setDisplacementFactor

public void setDisplacementFactor(double factor)

Sets an optional displacement factor to apply to the tiles when computing their distance to the eye. Setting it to a number bigger that 1 (say 1.03) is useful when you want to draw anything on top of an object.

Parameters:

factor - the desired displacement factor

getDisplacementFactor

public double getDisplacementFactor()

Gets the displacement factor

Returns:

the current displacement factor

See Also:

#setDisplacementFactor()

setDrawQuickInterior

public void setDrawQuickInterior(boolean draw,
                                 int transparency)

Draw a transparent interior when in quickDraw mode. Default is false

Parameters:

draw - the value desired

transparency - the desired level of transparency (from 0=fully transparent to 255=opaque)

setColorBelowWhenEqual

public void setColorBelowWhenEqual(boolean belowWhenEqual)

Whether a value equal to one of the thresholds should be drawn using the color below or above

Parameters:

belowWhenEqual - true to use the color below, false to use teh color above

setColorOriginAndDirection

public void setColorOriginAndDirection(double[] origin,
                                       double[] direction)

Sets the origin and direction of the color change. Default is (0,0,0) and (0,0,1), giving z-coded regions

Parameters:

origin - double[]

direction - double[]

setColorRegions

public void setColorRegions(double[] thresholds,
                            java.awt.Color[] colors)

Set the levels and color for regional color separation

Parameters:

thresholds - an array on n doubles that separate the n+1 regions. null for no region separation

colors - an array on n+1 colors, one for each of the regions

getTargetHit

protected InteractionTarget getTargetHit(int x,
                                         int y)

Description copied from class: Element

Gets the target that is under the (x,y) position of the screen

Overrides:

getTargetHit in class Element

Parameters:

x - int

y - int

Returns:

InteractionTarget

computeCorners

protected abstract void computeCorners()

This will be used by subclasses whenever there is a need to recompute the actual values of the corners before drawing. Synchronization is recomended.

setCorners

protected void setCorners(double[][][] _data)

projectPoints

protected void projectPoints()
