Method Detail

getPixelARGB

public abstract int getPixelARGB(int xd,
                                 int yd,
                                 double xu,
                                 double yu,
                                 double zu,
                                 double x3d,
                                 double y3d,
                                 double z3d)

Returns the color, as an ARGB-encoded integer, of the given pixel. xd, yd are the device coordinates (transformed by the chart's projection then by the Graphics2D transform). xu, yu, zu are the user coordinates (transformed by the chart's projection). x3d, y3d, z3d are the 3-d coordinates (untransformed).

Returns:

A 24-bit integer denoting a color, usually combined with an alpha mask of 0xFF000000.

createContext

protected PaintContext createContext(ColorModel cm,
                                     Rectangle deviceBounds,
                                     Rectangle2D userBounds,
                                     AffineTransform transform,
                                     ilog.views.chart.view3d.Ilv3DTransform transform3D,
                                     ilog.views.chart.view3d.Ilv3DVector planeNormal,
                                     double planeConstant,
                                     RenderingHints hints)

Creates and return a PaintContext used to generate the color pattern for a piece of the scene that lies on a given plane.

Parameters:

cm - The ColorModel that receives the data. This is only a hint.

deviceBounds - The bounding box in device space.

userBounds - The bounding box in user space.

transform - The AffineTransform that maps user space coordinates to device space coordinates.

transform3D - The 3D transformation of the view.

planeNormal - The normal vector of the given plane.

planeConstant - The constant part of the plane's equation.

hints - The set of hints in use for rendering.

createPlaneRestrictedPaint

public Paint createPlaneRestrictedPaint(ilog.views.chart.view3d.Ilv3DTransform transform3D,
                                        ilog.views.chart.view3d.Ilv3DVector planeNormal,
                                        double planeConstant)

Parameters:

transform3D - The 3D transformation of the view.

planeNormal - The normal vector of the given plane.

planeConstant - The constant part of the plane's equation.

Returns:

A Paint object that can be used for the points in the given plane.
