Detailed Description

MeshViz Defines a regular cartesian grid surface mesh.

Class to define a surface mesh represented by a grid, with cartesian coordinates, of which the lines are parallel to X-axis or Y-axis. This mesh is said regular because the gap between 2 consecutive parallel lines is constant.

The geometry of such a mesh is defined by the 2 dimensions of its grid (num_x,num_y), by its bounding box (x_min,y_min,x_max,y_max) and for a 3D mesh by its z altitudes on each nodes. z is an array of num_x * num_y floats.

The values on the mesh nodes are defined by the PbMesh::addValuesSet(set_index,val) method, where val argument is an array of num_x * num_y floats.

Member Function Documentation

virtual const PbCell* PbRegularCartesianGrid2D::findContainingCell ( const SbVec3f point,
float  tolerance,
SbVec3f pcoord 
) const [virtual]

Find the mesh's cell that contains the point.

If the (optional) adjacent cell is given, searching the containing cell starts by the cells around this adjacent one. Returns also the parametric coordinates of the point in the found cell. Parametric coordinates are the coordinates of the point relative to a topologically equivalent unit cell. A point is inside a cell if its parametric coordinates range from 0 to 1. However we use a test with a tolerance value: a point is inside the cell if its parametric coordinates p verify -tolerance <= p <= 1+tolerance. Parametric coordinates are useful to interpolate the value in the cell (see PbCell::getValue). Attention! This method returns always the same address of an internal private cell. This private cell is updated each time findContainingCell is called. If the cell exists, it returns a PbPixelCell for a 2D mesh, or a PbQuadrangleCell for a 3D mesh.

Reimplemented from PbMesh.

virtual const PbCell* PbRegularCartesianGrid2D::findContainingCell ( const SbVec3f point,
float  tolerance,
SbVec3f pcoord,
const PbCell adjacent_cell 
) const [virtual]

Reimplemented from PbMesh.

virtual float PbRegularCartesianGrid2D::getArea (  )  const [virtual]

Gets the area of the mesh.

Reimplemented from PbMesh2D.

virtual const PbCell* PbRegularCartesianGrid2D::getCell ( int  cell_index  )  const [virtual]

Gets the cell which index is cell_index.

Returns NULL if the cell does not exist. If the cell exists, it returns a PbPixelCell for a 2D mesh, or a PbQuadrangleCell for a 3D mesh. Attention! This method returns always the same address of an internal private cell. This private cell is updated each time getCell is called.
