Interface ContourPlot.Renderer

All Superinterfaces:

ContourPlot.PDFRenderer

All Known Implementing Classes:

ContourPlot.CompleteRenderer, ContourPlot.CoordSysRenderer, ContourPlot.GenericRenderer, ContourPlot.Legend, ContourPlot.LinesRenderer, ContourPlot.TextRenderer, ContourPlot.TrianglesRenderer

Enclosing class:

ContourPlot

public static interface ContourPlot.Renderer
extends ContourPlot.PDFRenderer

The Renderer interface defines methods to initialize the renderer, execute a rendering pass, close the renderer.

Implementation Notice:
If this renderer directly uses a shader, its fragment shader is obliged to output color for two buffers, which are the two color attachments of an

invalid reference

FBO

. These have to be written to
layout(location=0) out vec4 c1; and
layout(location=1) out vec4 c2;.
When the renderer has no use for the picking attachment, vec4(0,0,0,0) can be written as default.

Method Details

renderFallback

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

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

isEnabled

boolean isEnabled()

Whether this renderer is enabled or not. By default a renderer is enabled and will render upon

invalid reference

#render(int, int, int, int)

or

invalid reference

#renderSVG(org.w3c.dom.Document, org.w3c.dom.Element, int, int)

. When disabled those methods return right away and will not render anything.

Returns:

true when active
