Detailed Description

Projects curve points from a vtkMRMLMarkupsCurveNode to the surface of a model.

If the inputCurveNode set by SetInputCurveNode does not have a surface constraint node, this filter will act as a pass through and leave the points unchanged.

The intended use is for vtkMRMLMarkupsCurveNode to project generated points along a curve to a surface. It is expected that the points given to SetInputData/SetInputConnection are actually along the curve defined by the curve node's control point positions world.

This class is not meant to be a general purpose point projection filter.

◆ ConstrainPointsToSurface()

static bool vtkProjectMarkupsCurvePointsFilter::ConstrainPointsToSurface ( vtkPoints *  originalPoints,
vtkDoubleArray *  normalVectors,
vtkPolyData *  surfacePolydata,
vtkPoints *  surfacePoints,
double  maximumSearchRadiusTolerance 

Constrain points to a specified model surface.

originalPointsThe points to constrain.
normalVectorsThe normals for the originalPoints.
surfacePolydataThe surface to constrain to.
[out]surfacePointsThe points data structure to put the constrained points in.
maximumSearchRadiusToleranceMaximum distance a point can be constrained, specified as a percentage of the model's bounding box diagonal in world coordinate system. Valid range for this is 0 to 1.
true if successful, false otherwise.

◆ SetInputCurveNode()

void vtkProjectMarkupsCurvePointsFilter::SetInputCurveNode ( vtkMRMLMarkupsCurveNode inputCurveNode)

Sets the input curve node.

The surface model to project to is retrieved using vtkMRMLMarkupsCurveNode::GetSurfaceConstraintNode() and the input curve's control points are retrieved using vtkMRMLMarkupsCurveNode::GetControlPointPositionsWorld().

If the inputCurveNode does not have a surface constraint node, this filter acts as a pass through and leave the points unchanged.

It does not take ownership of the node and will not extend its lifetime.

If the inputCurveNode is deleted during this object's lifetime it will be as if nullptr was passed into this function.

◆ SetMaximumSearchRadiusTolerance()

void vtkProjectMarkupsCurvePointsFilter::SetMaximumSearchRadiusTolerance ( double  maximumSearchRadiusTolerance)

Set/Get maximumSearchRadiusTolerance defining the allowable projection distance.

It is specified as a percentage of the model's bounding box diagonal in world coordinate system.
