public class TriangleTerrain
extends TerrainModel

The TriangleTerrain class respresents the Java3D shape of a set of measurepoints. Before this Terrrain can be drawn the createTerrain method must be invoked, it will create triangles of the given measurepoints and will add the optional texture to the apearance of the Shap3D.

Constructor Detail

TriangleTerrain

public TriangleTerrain(List<Point> measurePoints,
                       Point lowerLeft,
                       Point lowerRight,
                       Point upperRight,
                       Point upperLeft,
                       double minimalHeightlevel,
                       double scale)

Parameters:

measurePoints - indicating height values inside this terrain. They will be triangulated in the createTerrain method.

lowerLeft - the lowerLeft point defining the area of this terrain.

lowerRight - the lowerRight point defining the area of this terrain.

upperRight - the upperRight point defining the area of this terrain.

upperLeft - the upperLeft point defining the area of this terrain.

minimalHeightlevel - which will be used if the measurepoints have no height set.

scale - to multiply onto the z-value of the measurepoints

Method Detail

getBoundingBox

public Envelope getBoundingBox()

Returns:

the boundingBox of this TriangleTerrain

createTerrain

public void createTerrain()

Description copied from class: TerrainModel

This method implements all the necessary steps to generate a Shape3D Terrain (Elevation model). Before rendering this Class this method should therefor be called prior.

Specified by:

createTerrain in class TerrainModel

createVerticalSeam

public void createVerticalSeam(TriangleTerrain neighbour)

Finds ther heights in the proximity of the border and creates the heights on the seam which will be added to the (wfs) measure-points of both the caller and the argument.

Parameters:

neighbour - the right neighbour of the envelope of this resolutionstripe. ______seam__________ | this | neighbour ________|___________ seam

createHorizontalSeam

public void createHorizontalSeam(TriangleTerrain neighbour)

Finds ther heights in the proximity of the border and creates the heights on the seam which will be added to the (wfs) measure-points of both the caller and the argument.

Parameters:

neighbour - the upper neighbour of the envelope of this resolutionstripe. | | | neighbour | seam -------------seam | this | | | leftBorder rightBorder
