-- File: Graphic3d_ArrayOfPolygons.cdl
-- Created: 04/01/01 : GG : G005 : Draw ARRAY primitives
class ArrayOfPolygons from Graphic3d inherits ArrayOfPrimitives from Graphic3d
is
-- constructor
Create (
maxVertexs: Integer from Standard;
maxBounds: Integer from Standard = 0;
maxEdges: Integer from Standard = 0;
hasVNormals: Boolean from Standard = Standard_False;
hasVColors: Boolean from Standard = Standard_False;
hasBColors: Boolean from Standard = Standard_False;
hasTexels: Boolean from Standard = Standard_False;
hasEdgeInfos: Boolean from Standard = Standard_False)
returns mutable ArrayOfPolygons from Graphic3d;
---Purpose: Creates an array of polygons,
-- a polygon can be filled as:
-- 1) creating a single polygon defined with his vertexs.
-- i.e:
-- myArray = Graphic3d_ArrayOfPolygons(7)
-- myArray->AddVertex(x1,y1,z1)
-- ....
-- myArray->AddVertex(x7,y7,z7)
-- 2) creating separate polygons defined with a predefined
-- number of bounds and the number of vertex per bound.
-- i.e:
-- myArray = Graphic3d_ArrayOfPolygons(7,2)
-- myArray->AddBound(4)
-- myArray->AddVertex(x1,y1,z1)
-- ....
-- myArray->AddVertex(x4,y4,z4)
-- myArray->AddBound(3)
-- myArray->AddVertex(x5,y5,z5)
-- ....
-- myArray->AddVertex(x7,y7,z7)
-- 3) creating a single indexed polygon defined with his vertex
-- ans edges.
-- i.e:
-- myArray = Graphic3d_ArrayOfPolygons(4,0,6)
-- myArray->AddVertex(x1,y1,z1)
-- ....
-- myArray->AddVertex(x4,y4,z4)
-- myArray->AddEdge(1)
-- myArray->AddEdge(2)
-- myArray->AddEdge(3)
-- myArray->AddEdge(1)
-- myArray->AddEdge(2)
-- myArray->AddEdge(4)
-- 4) creating separate polygons defined with a predefined
-- number of bounds and the number of edges per bound.
-- i.e:
-- myArray = Graphic3d_ArrayOfPolygons(6,4,14)
-- myArray->AddBound(3)
-- myArray->AddVertex(x1,y1,z1)
-- myArray->AddVertex(x2,y2,z2)
-- myArray->AddVertex(x3,y3,z3)
-- myArray->AddEdge(1)
-- myArray->AddEdge(2)
-- myArray->AddEdge(3)
-- myArray->AddBound(3)
-- myArray->AddVertex(x4,y4,z4)
-- myArray->AddVertex(x5,y5,z5)
-- myArray->AddVertex(x6,y6,z6)
-- myArray->AddEdge(4)
-- myArray->AddEdge(5)
-- myArray->AddEdge(6)
-- myArray->AddBound(4)
-- myArray->AddEdge(2)
-- myArray->AddEdge(3)
-- myArray->AddEdge(5)
-- myArray->AddEdge(6)
-- myArray->AddBound(4)
-- myArray->AddEdge(1)
-- myArray->AddEdge(3)
-- myArray->AddEdge(5)
-- myArray->AddEdge(4)
-- <maxVertexs> defined the maximun allowed vertex number in the array.
-- <maxBounds> defined the maximun allowed bound 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 <hasBColors> is TRUE , <maxBounds> must be > 0 and
-- you must use the
-- AddBound(number,Color) method.
-- 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 polygon
-- 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).
