-u1,v1 are the parameters of the point on Surf1
-u2,v2 are the parameters of the point on Surf2
-Order is the required continuity:
GeomAbs_C0 GeomAbs_C1 GeomAbs_C2
GeomAbs_G1 GeomAbs_G2
-EpsNul is used to detect a a vector with nul
magnitude
-EpsC0 is used for C0 continuity to confuse two
points (in mm)
-EpsC1 is an angular tolerance in radians used
for C1 continuity to compare the angle between
the first derivatives
-EpsC2 is an angular tolerance in radians used
for C2 continuity to compare the angle between
the second derivatives
-EpsG1 is an angular tolerance in radians used
for G1 continuity to compare the angle between
the normals
-Percent : percentage of curvature variation (unitless)
used for G2 continuity
- Maxlen is the maximum length of Surf1 or Surf2 in
meters used to detect null curvature (in mm)
the constructor computes the quantities which are
necessary to check the continuity in the following cases:
case C0
--------
- the distance between P1 and P2 with P1=Surf (u1,v1) and
P2=Surfv2(u2,v2)
case C1
-------
- the angle between the first derivatives in u :
dSurf1(u1,v1) dSurf2(u2,v2)
----------- and ---------
du du
the angle value is between 0 and PI/2
- the angle between the first derivatives in v :
dSurf1(u1,v1) dSurf2(u2,v2)
-------- and ---------
dv dv
- the ratio between the magnitudes of the first derivatives in u
- the ratio between the magnitudes of the first derivatives in v
the angle value is between 0 and pi/2
case C2
-------
- the angle between the second derivatives in u
2 2
d Surf1(u1,v1) d Surf2(u2,v2)
---------- ----------
2 2
d u d u
the ratio between the magnitudes of the second derivatives in u
- the ratio between the magnitudes of the second derivatives in v
the angle value is between 0 and PI/2
case G1
-------
-the angle between the normals at each point
the angle value is between 0 and PI/2
case G2
-------
- the maximum normal curvature gap between the two
points
