15 class ArrayOfTriangles from Graphic3d inherits ArrayOfPrimitives from Graphic3d
21 maxVertexs: Integer from Standard;

23 hasVNormals: Boolean from Standard = Standard_False;
24 hasVColors: Boolean from Standard = Standard_False;
25 hasTexels: Boolean from Standard = Standard_False)
26 returns ArrayOfTriangles from Graphic3d;
27 ---Purpose: Creates an array of triangles,
28 -- a triangle can be filled as:
29 -- 1) creating a set of triangles defined with his vertexs.
31 -- myArray = Graphic3d_ArrayOfTriangles(6)
32 -- myArray->AddVertex(x1,y1,z1)
34 -- myArray->AddVertex(x6,y6,z6)
35 -- 3) creating a set of indexed triangles defined with his vertex
38 -- myArray = Graphic3d_ArrayOfTriangles(4,6)
39 -- myArray->AddVertex(x1,y1,z1)
41 -- myArray->AddVertex(x4,y4,z4)
42 -- myArray->AddEdge(1)
43 -- myArray->AddEdge(2)
44 -- myArray->AddEdge(3)
45 -- myArray->AddEdge(2)
46 -- myArray->AddEdge(3)
47 -- myArray->AddEdge(4)
49 -- <maxVertexs> defined the maximun allowed vertex number in the array.
50 -- <maxEdges> defined the maximun allowed edge number in the array.
52 -- When <hasVNormals> is TRUE , you must use one of
53 -- AddVertex(Point,Normal)
54 -- or AddVertex(Point,Normal,Color)
55 -- or AddVertex(Point,Normal,Texel) methods.
56 -- When <hasVColors> is TRUE , you must use one of
57 -- AddVertex(Point,Color)
58 -- or AddVertex(Point,Normal,Color) methods.
59 -- When <hasTexels> is TRUE , you must use one of
60 -- AddVertex(Point,Texel)
61 -- or AddVertex(Point,Normal,Texel) methods.
63 -- the user is responsible about the orientation of the triangle
64 -- depending of the order of the created vertex or edges and this
65 -- orientation must be coherent with the vertex normal optionnaly
66 -- given at each vertex (See the Orientate() methods).
