class VertexNC from Graphic3d inherits VertexN from Graphic3d
---Version:
---Purpose: This class allows the creation of a vertex with
-- a colour and a 3D normal.
---Keywords: Vertex, Normal, Color, Coordinate, Point

Create
returns VertexNC from Graphic3d;
---Level: Public
---Purpose: Creates a point with coordinates 0.0, 0.0, 0.0
-- for which the normal is 0.0, 0.0, 1.0 and
-- the colour is Quantity_NOC_WHITE.
Create ( AX, AY, AZ : Real from Standard;
ANX, ANY, ANZ : Real from Standard;

---Level: Public
---Purpose: Creates a point with coordinates <AX>, <AY>, <AZ>
-- for which the normal is <ANX>, <ANY>, <ANZ> and
-- the colour is <AColor>.
-- If <FlagNormalise> is True the normal is already normalised
-- Else the normal is not normalised, the graphic do it.

---Level: Public
---Purpose: Creates a point in <APoint> for which the normal
-- is <AVector> and the colour is <AColor>.
-- If <FlagNormalise> is True the normal is already normalised
