public class PbCell extends PbBase
Defines an abstract cell of a mesh. A cell is a "simple" basic volume or surface element that connects adjacent nodes of a mesh.

  • Method Details

    • 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
