6.8.2 Elastic Flying Carpet
In this example we will show you how to create freeform mesh, which
moves along control curves like an elastic rubber carpet (if you have
not seen rubber carpets before, don't worry. I'm sure there are such
things as rubber carpets). We also demonstrate the use of links just to
make sure that you get familiar with them.
1. Create a mesh using the function Create/Freeform/Mesh.
2. Make the mesh the current level by double-clicking it on the Select
window; as usual, we will put sub-groups under the freeform level
itself.
3. Subdivide the mesh horizontally to groups, so each group consists of
a column of control points. Note that you have to turn Drawing Set/C.
Polyg. representation on (deselect "Curve" gadget at the same time)
in order to get access to the control points of the mesh.
4. Create a CONTROL CURVES method object.
5. Create two control curves to the same level with the the mesh.
6. Create two links pointing to the control curves (multi-select the
control curves and use the menu Create/Structure/Link).
7. Modify/Structure/Cut the links, make the CONTROL CURVES method the
current level and Modify/Structure/Paste the links back.
