class MeshDomain from StlMesh inherits TShared from MMgt
---Purpose: A mesh domain is a set of triangles defined with
-- three geometric vertices. The mesh domain has its
-- own deflection.
--
uses
SequenceOfXYZ from TColgp,
SequenceOfMeshTriangle from StlMesh
raises
NegativeValue from Standard,
NullValue from Standard
is
Create returns mutable MeshDomain;
---Purpose: The mesh deflection is defaulted to Confusion from
-- package Precision.
Create (Deflection : Real) returns mutable MeshDomain
raises NegativeValue,
---Purpose: Raised if the deflection is lower than zero
NullValue;
---Purpose: Raised if the deflection is lower than Confusion
-- from package Precision
AddTriangle (me : mutable; V1, V2, V3 : Integer; Xn, Yn, Zn : Real)
returns Integer
---Purpose: Build a triangle with the triplet of vertices (V1,
-- V2, V3). This triplet defines the indexes of the
-- vertex in the current domain The coordinates Xn,
-- Yn, Zn defines the normal direction to the
-- triangle. Returns the range of the triangle in
-- the current domain.

AddVertex (me : mutable; X, Y, Z : Real) returns Integer
---Purpose: Returns the range of the vertex in the current
-- domain.
is virtual;
AddOnlyNewVertex (me : mutable; X, Y, Z : Real; IsNew : in out Boolean)

---Purpose: Returns the range of the vertex in the current
-- domain. The current vertex is not inserted in the
-- mesh if it already exist.
