Package gov.nih.mipav.model.algorithms

Class ContourPlot.LinesRenderer

java.lang.Object

gov.nih.mipav.model.algorithms.ContourPlot.GenericRenderer<ContourPlot.Lines>

gov.nih.mipav.model.algorithms.ContourPlot.LinesRenderer

All Implemented Interfaces:

ContourPlot.AdaptableView, ContourPlot.PDFRenderer, ContourPlot.Renderer

Enclosing class:

ContourPlot

public class ContourPlot.LinesRenderer
extends ContourPlot.GenericRenderer<ContourPlot.Lines>

The LinesRenderer is an implementation of the ContourPlot.GenericRenderer for ContourPlot.Lines. This renderer uses a geometry shader that extends a line primitive into a quad of width that corresponds to the line width of the Lines object.
Its fragment shader draws the picking color into the second render buffer alongside the 'visible' color that is drawn into the first render buffer.

Method Details

renderFallback

public void renderFallback(Graphics2D g,
 Graphics2D p,
 int w,
 int h)

Description copied from interface: ContourPlot.Renderer

Renders this ContourPlot.Renderer's 'scene'. This is the fallback path in case OpenGL based rendering through

invalid reference

#render(int, int, int, int)

is not available.

Parameters:

g - main graphics object for drawing onto the framebuffer

p - graphics object for drawing onto the picking framebuffer (invisible but used for picking)

w - width of the current viewport in pixels

h - height of the current viewport in pixels
