Enclosing class:

public class ContourPlot.Points
extends Object
implements ContourPlot.Renderable

The Points class is a collection of 2D points that are to be represented using the same ContourPlot.Glyph (the graphical representation of a point). A point instance in this collection has the following attributes.

• position - the 2D location of the point
• scaling - the scaling of the glyph it is represented with
• rotation - the rotation of the glyph it is represented with
• color - the color with wich the glyph it is renered
• picking color - the picking color with which the glyph is rendered into the (invisible) picking color attachment of an

  . This color may serve as an identifier of the object that can be queried from a location of the rendering canvas. It may take on a value in range of 0xff000001 to 0xffffffff (16.777.214 possible values) or 0.

Apart from these per point attributes, this ContourPlot.Points class features a global scaling parameter by which all point instances of this collection will be scaled at rendering (

). Also a global alpha multiplier which scales every points color alpha value, which can be used to introduce transparency for all points of this collection, which may come in handy to visualize density when plotting a huge amount of points.

Points

public Points()

Creates a new ContourPlot.Points object which uses

invalid reference

DefaultGlyph#CIRCLE_F

for displaying its points.

Method Details

numPoints

public int numPoints()

Returns:

the number of points in this in this ContourPlot.Points object.

isDirty

public boolean isDirty()

Description copied from interface: ContourPlot.Renderable

if true, indicates that a call to

invalid reference

#updateGL(boolean)

is necessary to sync this objects GL resources to its current state.

Specified by:

isDirty in interface ContourPlot.Renderable

Returns:

true if dirty

intersects

public boolean intersects(Rectangle2D rect)

Description copied from interface: ContourPlot.Renderable

tests if this ContourPlot.Renderable intersects or contains the specified rectangle.

Specified by:

intersects in interface ContourPlot.Renderable

Parameters:

rect - rectangle to test

Returns:

true when intersecting

getPointDetails

public ArrayList<ContourPlot.PointDetails> getPointDetails()

Returns:

the list of point details.
Make sure to call

invalid reference

#setDirty()

when manipulating.
