Function BBTree.QueryClosest

void QueryClosest (

float3	p	Point to search around
NNConstraint	constraint	Optionally set to constrain which nodes to return
inProjectionParams	projection	Projection parameters derived from the constraint
ref float	distanceSqr	The best squared distance for the previous solution. Will be updated with the best distance after this search. Supply positive infinity to start the search from scratch.
refNNInfo	previous	This search will start from the previous NNInfo and improve it if possible. Will be updated with the new result. Even if the search fails on this call, the solution will never be worse than previous.
GraphNode[]	nodes	The nodes what this BBTree was built from
UnsafeSpan<int>	triangles	The triangles that this BBTree was built from
UnsafeSpan<Int3>	vertices	The vertices that this BBTree was built from

)

Queries the tree for the closest node to p constrained by the NNConstraint trying to improve an existing solution.

Note that this function will only fill in the constrained node. If you want a node not constrained by any NNConstraint, do an additional search with constraint = NNConstraint.None
