class HideData from DBRep
|
|
|
|
---Purpose: This class stores all the informations concerning
|
|
-- hidden lines on a view.
|
|
--
|
|
-- * View number
|
|
-- * Matrix of projection
|
|
-- * Type of projection, focal
|
|
-- * Arrays of 3d points
|
|
--
|
|
-- A drawable shape contains a list of such objects
|
|
-- to store the hidden lines for each view. The
|
|
-- IsSame method is used to check if hidden lines
|
|
-- must be recompiled.
