inline

Creates an array of triangle fans (Graphic3d_TOPA_TRIANGLEFANS), a polygon can be filled as: 1) Creating a single fan defined with his vertexes, 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);
