Hi Pilou,

> Of course I suppose than you can modify the form result by the history of the start curves ?

Yes!


> And for the next versions when you will have 4 curves that will be a little like coons curve?

Well, that would be like the already existing 2-rail sweep. But Coons patch is a little different than 2-rail sweep. I'm hoping to squeeze that in for the beta after this next one.


> Ps What is the name of this "one sweep" with special scale rails?

It's still the sweep command, there is a new "Pick scaling curve" option inside of sweep.

So I guess the name would be "Sweep with scaling curve".

Hi Jesse - yup definitely accessibility is better from having it built in. But also having it built in makes it possible to tweak the curves and have it update with history.

Usually an operation that is generated through a bunch of script is not as history friendly.

So cool sweet sweeps :)

Very nice Michael. MoI is already worth the price of admission and yet you just keep adding more goodies.

Looking forward to the next beta.

> I suppose also than the 3 curves can be open?

Any of the curves can be open, but the scaling curve won't have any effect if you have an open profile curve and the profiles are on the opposite side of the rail from the scaling curve.

Ok, additional scaling control is looking good for 2-rail sweeps now as well.

Here is an example from earlier in this thread where attempting to control the mouse shape by inserting more profiles caused a lumpy result:



This tends to be common when adding in a lot more profiles. There is just a lot of stuff happening, the rails are contributing one part to the scaling and then the morphing from one profile to another is another factor. It can be hard to control the resulting shape with all this stuff going on.

Now with the new scaling curve it allows more control over the stretching of the profiles. This is the result with the new scaling curve applied:



In fact in this case we could just use one profile and the scaling curve, the multiple profiles are no longer necessary just for attempting to get control over the height.

So I think these 2 new options (tangent preserving for half-shapes, and scaling curve) should help juice up sweep another couple of notches.

- Michael

Hi Pilou, here is some additional explanation.

Here is the setup for a normal 2-rail sweep:



The 2 rails are flat on the plane (one of the 2 rails is shown selected here), and the profile is sticking up vertically.

You can create a sweep from these curves, by selecting the profile and running Construct / Sweep, then selecting the rails. That will generate this surface (seen from the side here):



There is nothing terrible about this surface, but if you don't like the shape of the sweep as viewed from the side, it is difficult to change this in the current beta. In the next beta, the scaling curve option will give you an additional tool to control the shape as viewed from the side. This shows the side-profile scaling curve (shown here as the selected curve):



In the next beta, this curve can be applied to the sweep by clicking a new "Pick scaling curve" option that shows up along with the other sweep parameters. In this case applying the scaling curve (which should generally run down the center line of the sweep) will update the sweep to have this result, viewed from the side again:



The scaling curve is shown selected there. You can see that this has changed shape from the original sweep shown above - the sweep profiles (vertical sections) have been stretched to match up with the scaling curve. So now the side-view of the sweep has been adapted to have the same type of shape as the scaling curve.

Previously making this kind of an edit would have been difficult, you would have to try to put in a lot of vertical profiles to try and gain more control over the shape in the side view. But even as you added more profiles you would tend to get bumps. This new method does not not cause bumps.

So this helps you gain additional control over the shape of the sweep - it mostly adds control over the shape as viewed from the side-view.

Does that make more sense?

You might think of it as a kind of optional 3rd rail that can run down the center of a 2-rail sweep to provide additional control.

- Michael

Here's another interesting result. This is a one-rail sweep, with a nearby straight line set as the scaling rail.

Each cross-section of this shape is a different sized circle, but they are scaled in such a way to produce a straight line along that one side.

When you use a one-rail sweep with a scaling curve, the "Maintain height" checkbox will appear, which lets you control whether the scaling is a stretch in one direction (in the middle here) or a uniform scaling.



- Michael

This is some great stuff! Exactly what I was wishing for while making my most recent model. I'm really looking forward to the next beta...

Wow!
Hi Micheal, i found MOI a few day ago and i must say it's absolutly awesome!!
When i think how fast it is possible to model complex objects, i can't imagine that.
right now i try to use MOI for some complex objects. The Boole-function is great!
Absolutly perfect mesh. No bugs in the mesh. Dreamy! The Fillet-function.
Ever wanted to have something like this.
This is a scrennshot from my first serious try.


I need it for things like this:

(not done with moi, done with Cinema and renderd with FinalRender2)

















And i think in the future i will need it for nearly everything. :-)
Do you know what we'll have to pay for it when it's ready?

Janne

Found MOI, LOVE MOI, will buy MOI

Everything about B-W-Design

Very nice work !!!!!!

Hi Janne, that's a fantastic result from your first serious try!

Those are also some great renderings and models that you've done in Cinema4D - so much detail! It looks like MoI should be useful for modeling a lot of those pieces.

The high quality n-gon mesh export should make MoI a nice companion to Cinema...

Did you notice that you can do a boolean operation between a solid and a planar curve? I mean for instance if you want to boolean away a circular hole all the way through the object you can just do the boolean using the circle instead of needing to extrude to a cylinder. You'll still need to extrude for cuts that do not go all the way through the object, but for ones going all the way through that can save some time.


> Do you know what we'll have to pay for it when it's ready?

It will be around US $200.

I'm glad that you like MoI!

- Michael

I agree, those are some seriously impressive results both on the modeling and rendering for your first as you said "serious" try with Moi. This is real nice! :)

Please keep on posting more.

Ok, here is the next one.
Just spent 10-15 min. Thats the result. Just played around.


I LOVE Moi.
I will buy Moi.
I just told every body in other forums about moi. Many downloaded and tried it. All of them love it!
A very nice peace of software.

Thanks for all those compliments. :-) Nice to here that.

And thanks for the tip about boole. must try it.

MOI rules!

Great work, your renderings are also very good!

This one looks good too! I love seeing the results of just a short period of time spent.

- Michael

Oh, thanks, nice to hear.
But, did you noticed that the clocks-renderings are not made with Moi?
