class Drawer from Prs3d inherits TShared from MMgt
|
|
|
|
---Purpose: A graphic attribute manager which governs how
|
|
-- objects such as color, width, line thickness and
|
|
-- deflection are displayed.
|
|
-- Prs3d_Drawer is the mother class of AIS_Drawer.
|
|
-- As such, it is its set functions which are called to
|
|
-- modify display parameters. In the example below we
|
|
-- can see that the AIS_Drawer is modified to set the
|
|
-- value of the deviation coefficient using a method
|
|
-- inherited from Prs3d_Drawer.
|
|
-- A drawer includes an instance of the Aspect classes
|
|
-- with particular default values.
