ContourPlot.Renderer (MIPAV API Documentation)

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 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 Detail
  - renderFallback
```
default void renderFallback(java.awt.Graphics2D g,
                            java.awt.Graphics2D p,
                            int w,
                            int h)
```
    Renders this ContourPlot.Renderer's 'scene'. This is the fallback path in case OpenGL based rendering through #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 #render(int, int, int, int) or #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
