Constructor & Destructor Documentation
◆ Graphic3d_ArrayOfTriangleFans() [1/2]
|
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);
myArray->AddVertex (x5, y5, z5);
....
myArray->AddVertex (x8, y8, z8);
The number of triangle really drawn is: VertexNumber() - 2 * Min(1, BoundNumber())
- Parameters
