Add the given points to the given TIN. In this exercise you do not need to simulate any algorithm, only to produce the correct solution. You can modify the given TIN by mouse. By clicking on two points, an edge will be added between them. Edges can also be modified by clicking. If the clicked edge is diagonal of a given quadrilateral, clicking the edge will replace it with the other diagonal of the same quadrilateral. If the edge is not a diagonal, then clicking it will remove the edge. By clicking on a triangle, the circumscribing circle of the triangle is shown. Valid triangles are highlighted when mouse is moved over them. |
