Collapse All
Syntax
C++
virtual int isPointInsideMPolygon(const OdGePoint3d& worldPt, OdGeIntArray& loopsArray, double tol = OdDbMPolygonCrossingFuzz) const;
Parameters
Parameters 
Description 
const OdGePoint3d& worldPt 
[in] Point in WCS.  
OdGeIntArray& loopsArray 
[out] Boundary indices array.  
double tol = OdDbMPolygonCrossingFuzz 
[in] Measurement accuracy tolerance.
 
Returns

The function returns loopsArray.size().

Description

The function projects worldPt to the polygon plane, then if the point is on some boundary, indices of these boundaries are added to the loopsArray and the function returns, otherwise it finds the innermost loop containing the point and adds its index to the loopsArray before returning.
