Class PolyMeshRenderer

org.das2.graph.Renderer

org.das2.graph.PolyMeshRenderer

All Implemented Interfaces:

Displayable, Editable, DataSetConsumer

public class PolyMeshRenderer
extends Renderer

render a 2-D poly (typically triangle) mesh. This was introduced just to identify this schema. This renderer needs rank 3 data with 2 bundled datasets, the points in X-Y data space and the triangles (or polys) which connect them. When a rank 1 dataset with a triangleMesh as DEPEND_0 is passed in, then colors or text will be drawn. Note, QDataSet should not support a join of non-qube datasets, so all polygons should have the same length (all triangles or all four-sided polys). Most codes will work fine if this is not the case. Applications for this include marking data and drawing tesselations.

PolyMeshRenderer

public PolyMeshRenderer()

Method Detail

acceptsData

public static boolean acceptsData(QDataSet ds)

return true if the renderer accepts data in this form.

Parameters:

ds -

Returns:

doAutorange

public static QDataSet doAutorange(QDataSet ds)

autorange on the data, returning a rank 2 bounds for the dataset.

Parameters:

ds - the dataset to autorange.

Returns:

a bounds dataset, where result[0,:] is the xrange and result[1,:] is the yrange.

setControl

public void setControl(java.lang.String s)

Description copied from class: Renderer

set the control string which contains a number of properties. These are defined for each renderer, but they should try to be consistent. See http://autoplot.org/developer.guessRenderType#Proposed_extensions When overriding this, be sure to call super.

Overrides:

setControl in class Renderer

Parameters:

s - the control

See Also:

etc

getControl

public java.lang.String getControl()

Description copied from class: Renderer

get the string which summarizes the state of the renderer. These allow a compact string to contain the renderer settings. This should be an ampersand-delimited list of name=value pairs.

Overrides:

getControl in class Renderer

Returns:

render

public void render(java.awt.Graphics2D g,
                   DasAxis xaxis,
                   DasAxis yaxis)

Description copied from class: Renderer

Render is called whenever the image needs to be refreshed or the content has changed. This operation should occur with an animation-interactive time scale, and an image should be cached when this is not possible. The graphics object will have its origin at the upper-left corner of the screen.

Specified by:

render in class Renderer

Parameters:

g - the graphics context in the canvas reference frame.

xaxis - the axis relating x data coordinates to horizontal pixel coordinates

yaxis - the axis relating y data coordinates to horizontal pixel coordinates
