Full Version: Inconsistency in trim?

Show messages: All  1-12  13-16

HI geekmidget,

You seem to be trying to use the edit points as a diagnostic tool.

That's not really what they are intended to do.

In MOI the edit points are meant to provide a way to deform a curve. Since the regular NURBS control points for a precise circle or arc do not deform smoothly, there is a curve rebuild process applied to edit points. The rebuilt curve will be used if you move some of the points around.


re:
> I understand this but in both cases (270 degrees and 300 degrees) there are control points falling somewhere between two lines,

No that's not quite correct, the 300 degrees has "actual NURBS control points" like this:



And the 270 degree has this:


The 270 degree does not have any fully multiple knots interior to a trim span, they're all at the end of a span.

The 300 degree one has 2 spots where a fully multiple knot is internal to a trim instead of at the ends of a trim, those are the spots where the rebuild points will get 4 edit points.

Yes. You can put the quote inside <quote></quote> if you want.

Hi geekmidget,

re:
> I see, that naming seems counter-intuitive to me, but thanks! Now I get it.

Well, with the "control points" method the points you pick directly become the NURBS control points, I don't follow how that's counter-intuitive.

Try to watch the UI from the perspective of someone relatively new to MoI3D who just sees the icons and names of tools, not realizing the internals.

Actually I was trying to get the curve to follow the points precisely in the plane XY first to then assign each a Z value.


Thank you!
