GetPoint()

GPnt FaceIntersector.GetPoint

(

int

idx

)

Returns the geometric point of the ith intersection between the line and the surface.

Parameters

idx	the index, start from 0.

Returns

the point.

GetPointCount()

int FaceIntersector.GetPointCount

(

)

Get the intersecting point number

Returns

the count.

IsParallel()

boolean FaceIntersector.IsParallel

(

)

Test if curve is parallel or belongs face surface

Returns

Returns true if curve is parallel or belongs face surface.

Perform() [1/2]

boolean FaceIntersector.Perform	(	GLin	line,
