Class IndexedLineSet

All Implemented Interfaces:
X3DNode, IndexedLineSet, X3DGeometryNode

public class IndexedLineSet extends X3DConcreteNode implements IndexedLineSet
IndexedLineSet defines polyline segments using index lists corresponding to vertex coordinates.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. IndexedLineSet node tooltip: [X3DGeometryNode] IndexedLineSet defines polyline segments using index lists corresponding to vertex coordinates. IndexedLineSet is a geometry node that can contain a Coordinate|CoordinateDouble node and optionally a Color|ColorRGBA node.
  • Hint: Polygonal chain
  • Hint: either values in a contained Color node, or else Material emissiveColor in corresponding Appearance node, are used for rendering lines and points.
  • Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
  • Warning: use a different color (or Material emissiveColor) than the Background color, otherwise geometry is invisible.
  • Hint: adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines.
  • Hint: if rendering Coordinate points originally defined for an IndexedFaceSet, index values may need to repeat each initial vertex to close each polygon outline.
  • Hint: step-wise variation or linear interpolation of color values can be used as a good scientific visualization technique to map arbitrary function values to a color map.
  • Hint: insert a Shape node before adding geometry or Appearance.
  • Hint: for advanced extensibility, authors can substitute a type-matched ProtoInstance node (with correct containerField value) for contained node content.
  • Hint: consider including Fog (with Fog color matching Background color) to provide further depth cueing for IndexedLineSet (ILS).

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
