class Drawer from VrmlConverter inherits TShared from MMgt
---Purpose: qualifies the aspect properties for
-- the VRML conversation of a specific kind of object.
-- This includes for example color, maximal chordial deviation, etc...

is
Create returns mutable Drawer from VrmlConverter;
---Category: deviation definition.
--
-- All drawings of curves or patches are made with respect to a maximal
-- chordial deviation. This deviation is absolute and given through
-- the method: SetMaximalChordialDeviation.
--
-- In the case of drawing shapes, it is allowed to ask for a relative
-- deviation.
-- This deviation will be: SizeOfObject * DeviationCoefficient where
-- DeviationCoefficient can be set through the method: SetDeviationCoefficient.
--
--
-- For drawing algorithms using discretisation, a default number of
-- points has been set to 17. It is possible to use the method SetDiscret
-- to change this number.
--
SetTypeOfDeflection (me:mutable;
aTypeOfDeflection: TypeOfDeflection from Aspect);
---Purpose: by default: TOD_Relative; however, except for the shapes,
-- the drawing will be made using the absolute deviation.
--
TypeOfDeflection(me) returns TypeOfDeflection from Aspect;
SetMaximalChordialDeviation (me: mutable;
aChordialDeviation: Length from Quantity)
---Purpose: Defines the maximal chordial deviation when drawing any curve;
-- If this value is one of the obvious parameters of methods,
-- current value from Drawer won't be used.
-- This value is used by:
--
-- VrmlConverter_DeflectionCurve
-- VrmlConverter_WFDeflectionRestrictedFace

---Purpose: Defines the attributes which are used when drawing an
-- U isoparametric curve of a face. Defines the number
-- of U isoparametric curves to be drawn for a single face.
