iMesh::getCellForEndOfLine()

Description

Traverses along the surface of a ground mesh to disambiguate overlapping geometry at a target point.

Syntax

tSigned32 getCellForEndOfLine(const cPosition& start, tSigned32 endX, tSigned32 endY) const;

Parameters

	start		A position for the start of traversal. This must be a valid position on this mesh.
	endX		The x coordinate of the target.
	endY		The y coordinate of the target.

Return Value

The internal 'cell' index for the position reached by traversing from the start position to the target coordinates in a straight line along the surface of this mesh.
If the traversal exits the mesh then -1 is returned.
