Hello,
I wonder if it is possible to create a curve for which I know analytical equations.
For instance, I want to create
the curve corresponding to :
x(t)=0
y(t)=t
z(t)=sin(t)
Of course, I do not want to use bspline interpolation for that purpose (I already know how to do it !).
Thanks,
Frederic.

Yes it's possible, you just have to subclass Geom_Curve and re-implement all the pure virtual method (D0, D1, D2,...) so you will have to know the first derivative,... and then you will be able to use you Geom_CustomCurve and build an edge from it, display it using the AIS package, ...
Good Luck,
Francois.

Yes, it is true, you can do that.
The only problem is that you will not be able to save/load any Shape or Geometry created with Geom_CustomCurve without changing the whole OpenCASCADE code for reading/saving the geometry.
