class Display from Draw
|
|
|
|
---Purpose: Use to draw in a 3d or a 2d view.
|
|
--
|
|
-- * The 3d methods draw in the 3d system, in a 2d
|
|
-- view the drawing is projected on X,Y.
|
|
--
|
|
-- * The 2d methods draw in the projection plane.
|
|
--
|
|
-- * To draw in screen coordinates the length must be
|
|
-- divided by the zoom.
