Detailed Description

Clip a closed surface with a plane collection.

vtkClipClosedSurface will clip a closed polydata surface with a collection of clipping planes. It will produce a new closed surface by creating new polygonal faces where the input data was clipped. If GenerateOutline is on, it will also generate an outline wherever the clipping planes intersect the data. The ScalarMode option will add cell scalars to the output, so that the generated faces can be visualized in a different color from the original surface.

Warning
The triangulation of new faces is done in O(n) time for simple convex inputs, but for non-convex inputs the worst-case time is O(n^2*m^2) where n is the number of points and m is the number of 3D cavities. The best triangulation algorithms, in contrast, are O(n log n). There are also rare cases where the triangulation will fail to produce a watertight output. Turn on TriangulationErrorDisplay to be notified of these failures.

protected

Clip and contour polys in one step, in order to guarantee that the contour lines exactly match the new free edges of the clipped polygons. This exact correspondence is necessary in order to guarantee that the surface remains closed.

static int vtkClipClosedSurface::InterpolateEdge ( vtkPoints *  points,
vtkPointData *  pointData,
vtkCCSEdgeLocator *  edgeLocator,
double  tol,
vtkIdType  i0,
vtkIdType  i1,
double  v0,
double  v1,
vtkIdType &  i 
)
staticprotected

A helper function for interpolating a new point along an edge. It stores the index of the interpolated point in "i", and returns 1 if a new point was added to the points. The values i0, i1, v0, v1 are the edge enpoints and scalar values, respectively.

int vtkClipClosedSurface::TriangulatePolygon ( vtkIdList *  polygon,
vtkPoints *  points,
vtkCellArray triangles 
)
protected

A robust method for triangulating a polygon. It cleans up the polygon and then applies the ear-cut method that is implemented in vtkPolygon. A zero return value indicates that triangulation failed.

void vtkClipClosedSurface::TriangulateContours ( vtkPolyData data,
vtkIdType  firstLine,
vtkIdType  numLines,
vtkCellArray outputPolys,
const double  normal[3] 
)
protected

Given some closed contour lines, create a triangle mesh that fills those lines. The input lines must be single-segment lines, not polylines. The input lines do not have to be in order. Only lines from firstLine to will be used. Specify the normal of the clip plane, which will be opposite the the normals of the polys that will be produced. If outCD has scalars, then color scalars will be added for each poly that is created.

static void vtkClipClosedSurface::BreakPolylines ( vtkCellArray inputLines,
vtkCellArray outputLines,
vtkUnsignedCharArray *  inputScalars,
vtkIdType  firstLineScalar,
vtkUnsignedCharArray *  outputScalars,
const unsigned char  color[3] 
)
staticprotected

Break polylines into individual lines, copying scalar values from inputScalars starting at firstLineScalar. If inputScalars is zero, then scalars will be set to color. If scalars is zero, then no scalars will be generated.

static void vtkClipClosedSurface::CopyPolygons ( vtkCellArray inputPolys,
vtkCellArray outputPolys,
vtkUnsignedCharArray *  inputScalars,
vtkIdType  firstPolyScalar,
vtkUnsignedCharArray *  outputScalars,
const unsigned char  color[3] 
)
staticprotected

Copy polygons and their associated scalars to a new array. If inputScalars is set to zero, set polyScalars to color instead. If polyScalars is set to zero, don't generate scalars.

static void vtkClipClosedSurface::BreakTriangleStrips ( vtkCellArray inputStrips,
vtkCellArray outputPolys,
vtkUnsignedCharArray *  inputScalars,
vtkIdType  firstStripScalar,
vtkUnsignedCharArray *  outputScalars,
const unsigned char  color[3] 
)
staticprotected

Break triangle strips and add the triangles to the output. See CopyPolygons for more information.

static void vtkClipClosedSurface::SqueezeOutputPoints ( vtkPolyData output,
vtkPoints *  points,
vtkPointData *  pointData,
int  outputPointDataType 
)
staticprotected

Squeeze the points and store them in the output. Only the points that are used by the cells will be saved, and the pointIds of the cells will be modified.

static void vtkClipClosedSurface::CreateColorValues ( const double  color1[3],
const double  color2[3],
const double  color3[3],
unsigned char  colors[3][3] 
)
staticprotected

Take three colors as doubles, and convert to unsigned char.
