Class TLspPlotStyle

java.lang.Object
com.luciad.view.lightspeed.style.ALspStyle

All Implemented Interfaces:

Direct Known Subclasses:
TLspPlotStyle
public class TLspPlotStyle extends ALspStyle implements ILspWorldElevationStyle
This style represents a set of properties for point objects that can be controlled through expressions.

Construction of this style is done through its TLspPlotStyle.Builder.

This style can currently be used only in combination with a TLspPlotLayerBuilder.

Each property is calculated by an expression:

  • Visibility: determines whether the object is displayed or not
  • Icon: determines the icon to display
  • Scale: a scale factor applied to the icon
  • Color: a modulation color applied to the icon
  • Opacity: additional transparency applied to the icon
Additionally, you can enable other behavior:
  • Orientation: whether the icons should be rotated to match the orientation of the domain object, or be aligned with the screen.
  • Automatic scaling: varies the size of icons depending on the view's zoom level. This is strongly recommended for performance reasons. See TLspPlotStyle.Builder.automaticScaling(double) for details.
  • Eye-dome lighting: enhances the depth perception in data sets that have little or no visual variance (e.g. point clouds). See TLspEyeDomeLightingSettings for details.

For defaults, see TLspPlotStyle.Builder.

Example: 

   ILcdExpression<Boolean> visibilityExpression = eq(idAttribute, constant(43));
   ILcdExpression<ILcdIcon> iconExpression = ifThenElse(eq(classAttribute, constant(12)), someIcon, otherIcon);
   ILcdExpression<Float> opacityExpression = fraction(fuelBurnAttribute, 0, 13000);
   TLspPlotStyle style = TLspPlotStyle.newBuilder()
                                        .visibility(visibilityExpression)
                                        .icon(iconExpression)
                                        .opacity(opacityExpression)
                                        .build();
In this example, the object is visible if its ID is 43. The icon is determined by a class attribute, and the opacity depends on its fuel burn attribute.
