Detailed Description

Defines a pixel cell of a surface mesh.

A pixel cell is a rectangle of which edges are parallel to X, Y axes.

Nodes and edges are numbered as following :

                           3-----------2   edge 0 = 01
      j                    |           |   edge 1 = 12
                           |           |   edge 2 = 23
      |                    |           |   edge 3 = 30
      |                    |           |
      |                    |           |
      x------> i           0-----------1

float PbPixelCell::getArea

(

)

const [inline, virtual]

Gets the area of a cell.

Implements PbCell.

SbBox3f PbPixelCell::getBoundingBox

(

)

const [virtual]

Gets the cell's bounding box.

Reimplemented from PbCell.

Implements PbCell.

SbVec3f PbPixelCell::getValue	(	const SbVec3f &	pcoord,
		const SbVec3f *	v
	)			const [virtual]

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

Reimplemented from PbCell.

float PbPixelCell::getValue	(	const SbVec3f &	pcoord,
		const float *	s
	)			const [virtual]

virtual int PbPixelCell::locatePoint	(	const SbVec3f &	coord,
		float	tolerance,
		SbVec3f &	pcoord
	)			const [virtual]

Returns 1 if the point is inside the cell, 0 otherwise.

Gets also the parametric coordinate of the point and its weights

Implements PbCell.

PbPixelCell& PbPixelCell::operator=
