Hello all swamp people:
One thing really curious.A program to calculate and draw the normal to a region, it only works the sixth or eighth time running.
Running "C: REGIO-NORMAL" on the green and red regions, the results are unpredictable. After work the first time, the successes are repeated more often. Very surprising!. In other 3dregions the result is correct on the first try.
If anyone has any idea, I would be grateful.
Greetings.
PD.: The attached program has code of several people ( Gile and his wonderful ACISDECODE,...etc). It is your property, I only use it.
