getPrimitives

public java.util.List<Primitive> getPrimitives(org.meteoinfo.geometry.shape.PolygonZ polygon)
                                        throws PrimitiveTessellator.TesselationException

Tessellate a shape, transform it to a set of triangles. This method locks until rendering is completed.

参数:

shape - The shape to tessellate.

hole - Shape of the hole in the tessellation (optional).

返回:

A list of triangles that constitutes the shape.

抛出:

PrimitiveTessellator.TesselationException - Throws PrimitiveTessellator.TesselationException if the tessellation was unsuccessful, most commonly due to ambiguous shapes

getPrimitives

public void getPrimitives(org.meteoinfo.geometry.shape.PolygonZ polygon,
                          PrimitiveTessellator.TessellatorListener listener)

Tessellates a shape that is, tiling of the shape in a pattern of triangles that fills the shape with no overlaps and no gaps. Returns a set of triangles to the given PrimitiveTessellator.TessellatorListener whenever done.

参数:

shape - The shape to tessellate.

hole - Shape of the hole in the tessellation (optional).

listener - Instance of PrimitiveTessellator.TessellatorListener that will be invoked whenever tessellation is done or fails.

sendSuccess

protected void sendSuccess()

sendError

protected void sendError(java.lang.String message)
