findNumNeighbors()

static unsafe float MR.TriangulationHelpers.findNumNeighbors ( MR.Const_PointCloud pointCloud, MR.VertId v, int numNeis, MR.Std.Vector_MRVertId neighbors, MR.FewSmallest_MRPointsProjectionResult tmp, float? upDistLimitSq = null )

inlinestatic

Finds at most given number of neighbors of v (v excluded)

Parameters

tmp	temporary storage to avoid its allocation
upDistLimitSq	upper limit on the distance in question, points with larger distance than it will not be returned

Returns

maxDistSq to the furthest returned neighbor (or 0 if no neighbours are returned) Generated from function MR.TriangulationHelpers.findNumNeighbors. Parameter upDistLimitSq defaults to 3.40282347e38f.

isBoundaryPoint()

static unsafe bool MR.TriangulationHelpers.isBoundaryPoint ( MR.Const_PointCloud cloud, MR.VertId v, MR.TriangulationHelpers.Const_Settings settings, MR.TriangulationHelpers.TriangulatedFanData fanData )

inlinestatic

Checks if given vertex is on boundary of the point cloud, by constructing local triangulation around it.

Parameters

cloud	input point cloud
v	vertex id to check
settings	all parameters of the computation
fanData	cache structure for neighbors, not to allocate for multiple calls

Returns

true if vertex is boundary, false otherwise Generated from function MR.TriangulationHelpers.isBoundaryPoint.

updateNeighborsRadius()

static unsafe float MR.TriangulationHelpers.updateNeighborsRadius ( MR.Const_VertCoords points, MR.VertId v, MR.VertId boundaryV, MR.Std.Const_Vector_MRVertId fan, float baseRadius )

inlinestatic

Finds max radius of neighbors search, for possible better local triangulation.

Parameters

borderV	first boundary vertex in
fan	(next VertId in fan is also boundary but first is enough) Generated from function MR.TriangulationHelpers.updateNeighborsRadius.
