Detailed Description
template<typename BaseVecT>
class lvr2::PointsetSurface< BaseVecT >
An interface class to wrap all functionality that is needed to generate a surface approximation from point cloud data.
Classes that implement this interface can be used for Marching Cubes based mesh generation algorithms in via the SurfaceReconstruction interface.

Member Function Documentation
◆ calculateSurfaceNormals()
|
pure virtual |
Calculates surface normals for each data point in the given PointBuffeer. If the buffer alreay contains normal information it will be overwritten with the new normals.
Implemented in lvr2::AdaptiveKSearchSurface< BaseVecT >.
◆ distance()
|
pure virtual |
Returns the distance of vertex v from the nearest tangent plane.
- Parameters
-
p A grid point
- Returns
- The first value is the projected distance from the query point to the isosurface. The second value is the euclidian distance to the nearest data point.
Implemented in lvr2::AdaptiveKSearchSurface< BaseVecT >.
◆ getBoundingBox()
| const BoundingBox<BaseVecT>& lvr2::PointsetSurface< BaseVecT >::getBoundingBox | ( | ) | const |
Returns the bounding box of the point set.
◆ getInterpolatedNormal()
|
virtual |
Interpolates a surface normal at the given position.
- Parameters
-
position the position to calculate a normal for
- Returns
- The normal
◆ pointBuffer()
|
virtual |
Returns the internal point buffer. After a call of calculateSurfaceNormals the buffer will contain normal information.
◆ searchTree()
| std::shared_ptr<SearchTree<BaseVecT> > lvr2::PointsetSurface< BaseVecT >::searchTree | ( | ) | const |
Returns a pointer to the search tree.
◆ setKd()
|
inline |
Sets the number of points that is used for distance evaluation, i.e. an average of the distance to the k nearest data points is given (useful in noisy data sets).
Definition at line 128 of file PointsetSurface.hpp.
