Remarks

This class generates an extruded shape from a simple or a complex polyline. The line is extruded between the 2 planes parallel that can be specified with a boundingBox or directly in camera space (see OIV.Inventor.Misc.SbExtrusionGenerator.CreateFrom2DPoints(System.Collections.Generic.IList{{OIV.Inventor.SbVec2f}}, OIV.Inventor.SoPath, OIV.Inventor.SbViewVolume, OIV.Inventor.SbBox3f) methods) The generated shape is closed and contains only triangles in CCW order.

LIMITATIONS

Only vertices are handled in the generated shape, none of the normal, color or texCoord properties are taken into account.

NOTES

In an orthographic view, the polyline is extruded along the view vector (normal to the camera plane), but in a perspective view the generated shape is a truncated cone with a larger base farther from the camera, due to the perspective transform.
Local space refers to the space in which the shape will be expressed.
