Hi Paul,

Forget all the ASCII parts of the 2 previous mail, here is the good way to
fill the CPatchInfo::CBindInfo structure :

---

We will assume all patches in this example are oriented like this

0      3
  ***
  *  *
  ***
1      2

---

The edge numbers are :

      3
    ***
 0 *  * 2
    ***
      1

 ---

 There is 3 ways to bind patches together. (1-1, 1-2, 1-4)

 ---

 One patch on another :

 **********
 *      *        *
 *  0  *   1   *
 *      *        *
 **********
 CBindInfo:
 Patch 0, edge 2 : NPatchs = 1, Next = { Patch 1 }, Edge = { 0 }
 Patch 1, edge 0 : NPatchs = 1, Next = { Patch 0 }, Edge = { 2 }

 ---

 Two patches on another (Bind 2)

 **********
 *      *   2   *
 *  0  ******
 *      *   1   *
 **********
 Bind info:
 Patch 0, edge 2 : NPatchs = 2,  Next = { Patch 1, Patch 2 }, Edge = { 0,
0 }
 Patch 1, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }
 Patch 2, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }

 ---

 4 patches on another (Bind 4)

 **********
 *      *   4   *
 *      ******
 *      *   3   *
 *  0  ******
 *      *   2   *
 *      ******
 *      *   1   *
 **********
 Patch 0, edge 2 : NPatchs = 4,  Next = { Patch 1, Patch 2, Patch 3, Patch
4 }, Edge = { 0, 0, 0, 0 }
 Patch 1, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }
 Patch 2, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }
 Patch 3, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }
 Patch 4, edge 0 : NPatchs = 1,  Next = { Patch 0 }, Edge = { 2 }

Sorry but i have been confused by the two classes called CPatch::CBindInfo
and CPatchInfo::CBindInfo. :-)
