Remarks

Find nearest point on current mesh to given WorldPoint Requires that bBuildSpatialDataStructure = true unless bLinearSearch = true

Returns

nearest point in world space

Parameters

Parameter

Description

WorldPoint

point in world space

bLinearSearch

test every triangle. On a mesh where only a few queries will be run, this is faster than building the spatial data structure.
