|
---Purpose: Creates an array of triangles,
|
|
-- a triangle can be filled as:
|
|
-- 1) creating a set of triangles defined with his vertexs.
|
|
-- i.e:
|
|
-- myArray = Graphic3d_ArrayOfTriangles(6)
|
|
-- myArray->AddVertex(x1,y1,z1)
|
|
-- ....
|
|
-- myArray->AddVertex(x6,y6,z6)
|
|
-- 3) creating a set of indexed triangles defined with his vertex
|
|
-- ans edges.
|
|
-- i.e:
|
|
-- myArray = Graphic3d_ArrayOfTriangles(4,6)
|
|
-- myArray->AddVertex(x1,y1,z1)
|
|
-- ....
|
|
-- myArray->AddVertex(x4,y4,z4)
|
|
-- myArray->AddEdge(1)
|
|
-- myArray->AddEdge(2)
|
|
-- myArray->AddEdge(3)
|
|
-- myArray->AddEdge(2)
|
|
-- myArray->AddEdge(3)
|
|
-- myArray->AddEdge(4)
|
|
--
|
|
-- <maxVertexs> defined the maximun allowed vertex number in the array.
|
|
-- <maxEdges> defined the maximun allowed edge number in the array.
|
|
-- Warning:
|
|
-- When <hasVNormals> is TRUE , you must use one of
|
|
-- AddVertex(Point,Normal)
|
|
-- or AddVertex(Point,Normal,Color)
|
|
-- or AddVertex(Point,Normal,Texel) methods.
|
|
-- When <hasVColors> is TRUE , you must use one of
|
|
-- AddVertex(Point,Color)
|
|
-- or AddVertex(Point,Normal,Color) methods.
|
|
-- When <hasTexels> is TRUE , you must use one of
|
|
-- AddVertex(Point,Texel)
|
|
-- or AddVertex(Point,Normal,Texel) methods.
|
|
-- When <hasEdgeInfos> is TRUE , <maxEdges> must be > 0 and
|
|
-- you must use the
|
|
-- AddEdge(number,visibillity) method.
|
|
-- Warning:
|
|
-- the user is responsible about the orientation of the triangle
|
|
-- depending of the order of the created vertex or edges and this
|
|
-- orientation must be coherent with the vertex normal optionnaly
|
|
-- given at each vertex (See the Orientate() methods).
