Smooth the tangents of those zones.
Zones must be correclty welded. Only all patchs of zones[0] are parsed. But other zones may be modified on their edge (so you must save them).
NB: tangent smoothing is only done on bind 1/1. -
Parameters:
-
| zones |
The 0 is the center zone to be computed. Other are the 4 zones around (no special order needed). Doesn't matter if zones[i].Patchs is NULL. Also, if a neighbor patch is not found on a edge, then no error is generated: this patch edge is not modified. nlstop if zones[0]==NULL. |
| angleThreshold |
if angle beetween (patch_interior - tangent) and (neighbor_patch_interior - tangent) is above angleThreshold, no smooth is done on this tangent. Default: 30°. |
| continuityC1. |
when a smooth is done on a tangent, tangent is forced such that the 2 interiors and the tangent are colinear, so continuity G1 is assured. if continuityC1 is true, then tangent is set to the middle of the interiors (continuity C1). If false, tangent is setup so that previous distance ratio are kept. |
