a cell that represents an n-sided polygon
vtkPolygon is a concrete implementation of vtkCell to represent a 2D n-sided polygon. The polygons cannot have any internal holes, and cannot self-intersect. Define the polygon with n-points ordered in the counter- clockwise direction; do not repeat the last point.

Given parametric coordinates of a point, return the closest cell boundary, and whether the point is inside or outside of the cell.
The cell boundary is defined by a list of points (pts) that specify a face (3D cell), edge (2D cell), or vertex (1D cell). If the return value of the method is != 0, then the point is inside the cell.
Implements vtkCell.

overridevirtual |
Generate contouring primitives.
The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates). Contouring primitives can be vertices, lines, or polygons. It is possible to interpolate point data along the edge by providing input and output point data - if outPd is nullptr, then no interpolation is performed. Also, if the output cell data is non-nullptr, the cell data from the contoured cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.)
Implements vtkCell.
|
overridevirtual |
Cut (or clip) the cell based on the input cellScalars and the specified value.
The output of the clip operation will be one or more cells of the same topological dimension as the original cell. The flag insideOut controls what part of the cell is considered inside - normally cell points whose scalar value is greater than "value" are considered inside. If insideOut is on, this is reversed. Also, if the output cell data is non-nullptr, the cell data from the clipped cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.)
Implements vtkCell.

Given a point x[3] return inside(=1), outside(=0) cell, or (-1) computational problem encountered; evaluate parametric coordinates, sub-cell id (!=0 only if cell is composite), distance squared of point x[3] to cell (in particular, the sub-cell indicated), closest point on cell to x[3] (unless closestPoint is null, in which case, the closest point and dist2 are not found), and interpolation weights in cell.
(The number of weights is equal to the number of points defining the cell). Note: on rare occasions a -1 is returned from the method. This means that numerical error has occurred and all data returned from this method should be ignored. Also, inside/outside is determine parametrically. That is, a point is inside if it satisfies parametric limits. This can cause problems for cells of topological dimension 2 or less, since a point in 3D can project onto the cell within parametric limits but be "far" from the cell. Thus the value dist2 may be checked to determine true in/out.

Determine global coordinate (x[3]) from subId and parametric coordinates.
Also returns interpolation weights. (The number of weights is equal to the number of points in the cell.)

Intersect with a ray.
Return parametric coordinates (both line and cell) and global intersection coordinates, given ray definition p1[3], p2[3] and tolerance tol. The method returns non-zero value if intersection occurs. A parametric distance t between 0 and 1 along the ray representing the intersection point, the point coordinates x[3] in data coordinates and also pcoords[3] in parametric coordinates. subId is the index within the cell if a composed cell like a triangle strip.
Implements vtkCell.
Generate simplices of proper dimension.
If cell is 3D, tetrahedron are generated; if 2D triangles; if 1D lines; if 0D points. The form of the output is a sequence of points, each n+1 points (where n is topological cell dimension) defining a simplex. The index is a parameter that controls which triangulation to use (if more than one is possible). If numerical degeneracy encountered, 0 is returned, otherwise 1 is returned. This method does not insert new points: all the points that define the simplices are the points that define the cell.
Implements vtkCell.

overridevirtual |
Compute derivatives given cell subId and parametric coordinates.
The values array is a series of data value(s) at the cell points. There is a one-to-one correspondence between cell point and data value(s). Dim is the number of data values per cell point. Derivs are derivatives in the x-y-z coordinate directions for each data value. Thus, if computing derivatives for a scalar function in a hexahedron, dim=1, 8 values are supplied, and 3 deriv values are returned (i.e., derivatives in x-y-z directions). On the other hand, if computing derivatives of velocity (vx,vy,vz) dim=3, 24 values are supplied ((vx,vy,vz)1, (vx,vy,vz)2, ....()8), and 9 deriv values are returned ((d(vx)/dx),(d(vx)/dy),(d(vx)/dz), (d(vy)/dx),(d(vy)/dy), (d(vy)/dz), (d(vz)/dx),(d(vz)/dy),(d(vz)/dz)).

Return whether this cell type has a fixed topology or whether the topology varies depending on the data (e.g., vtkConvexPointSet).
This compares to composite cells that are typically composed of primary cells (e.g., a triangle strip composite cell is made up of triangle primary cells).

double vtkPolygon::ComputeArea | ( | ) |
Compute the area of a polygon.
This is a convenience function which simply calls static double ComputeArea(vtkPoints *p, vtkIdType numPts, vtkIdType *pts, double normal[3]); with the appropriate parameters from the instantiated vtkPolygon.
Compute the interpolation functions/derivatives.
(aka shape functions/derivatives) Two interpolation algorithms are available: 1/r^2 and Mean Value Coordinate. The former is used by default. To use the second algorithm, set UseMVCInterpolation to be true. The function assumes the input point lies on the polygon plane without checking that.

Compute the area of a polygon in 3D.
The area is returned, as well as the normal (a side effect of using this method). If you desire to compute the area of a triangle, use vtkTriangleArea which is faster. If pts==nullptr, point indexing is supposed to be {0, 1, ..., numPts-1}. If you already have a vtkPolygon instantiated, a convenience function, ComputeArea() is provided.

Create a local s-t coordinate system for a polygon.
The point p0 is the origin of the local system, p10 is s-axis vector, and p20 is the t-axis vector. (These are expressed in the modeling coordinate system and are vectors of dimension [3].) The values l20 and l20 are the lengths of the vectors p10 and p20, and n is the polygon normal.

Determine whether point is inside polygon.
Function uses ray-casting to determine if point is inside polygon. Works for arbitrary polygon shape (e.g., non-convex). Returns 0 if point is not in polygon; 1 if it is. Can also return -1 to indicate degenerate polygon.
Triangulate this polygon.
The user must provide the vtkIdList outTris. On output, the outTris list contains the ids of the points defining the triangulation. The ids are ordered into groups of three: each three-group defines one triangle.
Same as Triangulate(vtkIdList *outTris) but with a first pass to split the polygon into non-degenerate polygons.
Triangulate polygon and enforce that the ratio of the smallest triangle area to the polygon area is greater than a user-defined tolerance.

Method intersects two polygons.
You must supply the number of points and point coordinates (npts, *pts) and the bounding box (bounds) of the two polygons. Also supply a tolerance squared for controlling error. The method returns 1 if there is an intersection, and 0 if not. A single point of intersection x[3] is also returned if there is an intersection.

static |
Intersect two convex 2D polygons to produce a line segment as output.
The return status of the methods indicated no intersection (returns 0); a single point of intersection (returns 1); or a line segment (i.e., two points of intersection, returns 2). The points of intersection are returned in the arrays p0 and p1. If less than two points of intersection are generated then p1 and/or p0 may be indeterminiate. Finally, if the two convex polygons are parallel, then "0" is returned (i.e., no intersection) even if the triangles lie on one another.
