Constructor & Destructor Documentation

Graphic3d_ArrayOfTriangleFans::Graphic3d_ArrayOfTriangleFans ( const Standard_Integer  maxVertexs,
const Standard_Integer  maxFans = 0,
const Standard_Boolean  hasVNormals = Standard_False,
const Standard_Boolean  hasVColors = Standard_False,
const Standard_Boolean  hasFColors = Standard_False,
const Standard_Boolean  hasTexels = Standard_False 
)

Creates an array of triangle fans, a polygon can be filled as: 1) creating a single fan defined with his vertexs. i.e: myArray = Graphic3d_ArrayOfTriangleFans(7) myArray->AddVertex(x1,y1,z1) .... myArray->AddVertex(x7,y7,z7) 2) creating separate fans defined with a predefined number of fans and the number of vertex per fan. i.e: myArray = Graphic3d_ArrayOfTriangleFans(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. <maxFans> defined the maximun allowed fan number in the array. The number of triangle really drawn is : VertexNumber()-2*Min(1,BoundNumber())
