Method Detail

getValue

public float getValue(float[] weight,
                      float[] s)

Gets the scalar value of a point in this cell, given the point's weights.

getBoundingBox

public SbBox3f getBoundingBox()

Gets the cell's bounding box.

getLongestEdgeLength

public float getLongestEdgeLength()

Gets the length of the longest edge of the cell.

getValue

public SbVec3f getValue(float[] weight,
                        SbVec3f[] v)

Gets the vector value of a point in this cell, given the point's weights.

getValue

public SbVec3f getValue(SbVec3f pcoord,
                        SbVec3f[] v)

Get the vector value of a point in the cell.

Parameters:

pcoord - [in] Parametric [0..1] coordinate of the point inside the cell.

v - [in] The vector dataset to interpolate

Returns:

The interpolated value

getNumEdges

public int getNumEdges()

Gets the number of edges.

getNumFacets

public int getNumFacets()

Gets the number of facets.

getNodeCoord

public SbVec3f getNodeCoord(int nod)

Gets the coordinate of the nod (nod must be >=0 and < getNumNodes()).

getNodeIndex

public int getNodeIndex(int nod)

Gets the index (in the mesh) of a nod (nod must be >=0 and < getNumNodes()).

getNumNodes

public int getNumNodes()

Gets the number of nodes.

getIndex

public int getIndex()

Gets the index of the cell in the mesh.

getCenter

public SbVec3f getCenter()

Gets the cell's geometric center.

getBounds

public float[] getBounds()

Gets the cell's bounds. Similar to getBoundingBox() but it does not use any SbBox object.

getValue

public float getValue(SbVec3f pcoord,
                      float[] s)

Get the scalar value of a point in the cell.

Parameters:

pcoord - [in] Parametric [0..1] coordinate of the point inside the cell.

s - [in] The scalar dataset to interpolate

Returns:

The interpolated value

getArea

public float getArea()

Gets the area of a cell.

getVolume

public float getVolume()

Gets the volume of the cell. Returns always 0 for a 2D cell.

locatePoint

public SbVec3f locatePoint(SbVec3f coord,
                           float tolerance)

Returns 1 if the point is inside the cell, 0 otherwise. Gets also the parametric coordinate of the point and its weights
