public void assign(int[] vIndices,
                   float[] coordFloats,
                   float[] dataFloats,
                   int numDataAttributes,

intersects

public boolean intersects(Cell c)

Specified by:

intersects in class Cell

inside

public boolean inside(Point p)

Returns true if the Point p is inside the TriangleCell, false otherwise. Assumes 2D space for now.

inside

public static boolean inside(Point p,
                             float[] coords,
                             int startIndex)

Returns true if the Point p is inside the TriangleCell, false otherwise. This static method expects the points to be stored in an interleaved array of floats. P0x, P0y, P1x, P1y, P2x, P2y... the last argument specifies the index of the TriangleCell's zero'th vertex. Assumes 2D space for now.

inside

public static boolean inside(Point p,
                             int[] vIndices,
                             float[] coords,
                             int triangleIndex)

Returns true if the Point p is inside the TriangleCell, false otherwise. This static method expects the point coords to be stored in an interleaved array of floats. P0x, P0y, P1x, P1y, P2x, P2y... the third argument is an array of integers that specifies the location of coordinate pairs in the coords array for a collection of cells. The last argument specifies the location of a particular cell's vertex indices in the index array. Assumes 2D space for now.

boundingBox

public GBounds boundingBox()

boundingBox

public static GBounds boundingBox(int[] vIndices,
