OCC.Graphic3d module

-Version:This package permits the creation of 3d graphic objectsin a visualiser.These objects, called structures, are composed of groups ofprimitives and attributes.The group is the smallest editable element of a structure.A structure can be displayed, erased, high-lighted.A transformation can be applied to it.Structures can be connected to form a tree of structures,composed by transformations.The visualiser permits global manipulation of structures.-Keywords: Structure, Group, Primitives, Line, Marker, Text,FillAreas, Vertex, Vector, Material, Font, Shading-Warning:-References:

  • Creates an array of triangle strips, a polygon can be filled as: 1) creating a single strip defined with his vertexs. i.e: myArray = Graphic3d_ArrayOfTriangleStrips(7) myArray->AddVertex(x1,y1,z1) …. myArray->AddVertex(x7,y7,z7) 2) creating separate strips defined with a predefined number of strips and the number of vertex per strip. i.e: myArray = Graphic3d_ArrayOfTriangleStrips(8,2) myArray->AddBound(4) myArray->AddVertex(x1,y1,z1) …. myArray->AddVertex(x4,y4,z4) myArray->AddBound(4) myArray->AddVertex(x5,y5,z5) …. myArray->AddVertex(x8,y8,z8) //! <maxVertexs> defined the maximun allowed vertex number in the array. <maxStrips> defined the maximun allowed strip number in the array. The number of triangle really drawn is : VertexNumber()-2*Min(1,BoundNumber()) 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. Warning: the user is responsible about the orientation of the strip depending of the order of the created vertex and this orientation must be coherent with the vertex normal optionnaly given at each vertex (See the Orientate() methods).
Parameters:
  • maxVertexs (int) –

SetImmediateModeDrawToFront()
  • @param theDrawToFrontBuffer Advanced option to modify rendering mode: 1. True. Drawing immediate mode structures directly to the front buffer over the scene image. Fast, so preferred for interactive work (used by default). However these extra drawings will be missed in image dump since it is performed from back buffer. Notice that since no pre-buffering used the V-Sync will be ignored and rendering could be seen in run-time (in case of slow hardware) and/or tearing may appear. So this is strongly recommended to draw only simple (fast) structures. 2. False. Drawing immediate mode structures to the back buffer. The complete scene is redrawn first, so this mode is slower if scene contains complex data and/or V-Sync is turned on. But it works in any case and is especially useful for view dump because the dump image is read from the back buffer. returns previous mode.
