Sure, have at it: def FindClosestPoint( inObj, inPos): dist = 10000 ID = -1 Pos = XSIMath.CreateVector3() PosArr = inObj.ActivePrimitive.Geometry.Points.PositionArray for index in range(inObj.ActivePrimitive.Geometry.Points.Count): Pos.Set( PosArr[0][index], PosArr[1][index], PosArr[2][index] ) Pos.SubInPlace(inPos) D = Pos.Length() if D < dist: dist = D ID = index return ID
