Dear Michael,

As an hobbyist with very limited budget, I learned that the 3d navigation device Space Navigator Personal Edition from 3dconexxion is availbale for only Euro 51 (all other 3dconexxion device are much more expensive). So I did myself a favor and bought one.
Could you please add support for the 3d navigation devices in V1?

Support for 3dconexxion (alle device use the same driver) and a proper manual in V1 and price not above $200: if so I'm willing to preorder :)

Regards

Hans

Hi Hans, I do plan on working on 3dconexxion support, it will probably be one of the last things that I work on for V1.

Well, I think I'll have you covered. Price will be right around $200, and I will be working on a manual next month. But I'm not ready to take preorders yet... :)

Thanks Michael,

Thanks for implementing support for the connexion devices in V1. And indeed, you have me covered. Whenever you are ready for ordering, I will be happy to be one of your customers.

Best Regards.

Hans

Complaints by Steph
Seems for the Import OBJ that Moi gives Normal's facetts of "Open surface" transformed in Poly in impredictable result !
So does it possible to see the normals of Poly Surfaces (by color (?) and possibility to click on them for inverse it before export?

You can say take an another Poly prog for make that,
but seems that Moi Smooth Phong is very "complex"
and the other poly progs have many difficulties for manage this problem !

A new challenge ? :)
PS Or use an algorithm for make "Open surface" artificially like "Closed surface" for have Normal to the external?

Always by Steph
All was made by Moi (Symetry too)
problem on the left
After Symetry problem is inversed!!!
Open surfaces (transformed in poly) seems have a problem in Moi ?
It's some annoying for the export to the real time system :(

Hi Pilou - I think that what you are talking about here is that MoI exports nice smoothing information in a form called "vertex normals". These normals are very accurate since they come from the original NURBS surface.

It sounds like in Steph's polygon program (Cinema4D??) , flipping the direction of a mesh causes it to throw away existing vertex normals and calculate new ones - this is bad because the normals calculated "from scratch" in a polygon modeler come from just averaging adjacent polygon faces. This is not as accurate as the original normals and can cause shading defects.

Has Steph reported this problem to the makers of his polygon program? The authors of that program should improve the way they flip objects - instead of discarding the good normals they should just flip those normals to the other direction.

It is not really a difficult problem to solve at all, it is actually a very simple procedure, each normal should just get multiplied by -1.0.

- Michael

Hi Pilou,

I'm not sure that I completely understand, but one thing to try is to make sure to use Edit/Join to join surfaces that are next to each other so that they become one object that has a shared edge.

MoI should create polygons with a consistent direction on them when there are shared edges.

I'm not sure from just looking the image (instead of seeing a .3dm file), but it looks like the smaller object there has different orientations along each of its 3 surfaces - this is possible if they are surfaces that are just positioned next to each other instead of joined.

If there is an object that is all joined together but is generating meshes with inconsistent normals between different pieces of the same object, then that would be a bug. If this is the problem it would help to have an example model so I could fix the bug.


> Open surfaces (transformed in poly) seems have a problem in Moi ?

Well, open surfaces should work without a problem, but there is not an automatic "outside" direction that can be calculated for an open surface, unlike a closed surface.

However, I should be able to do something automatic for surfaces of revolution, even if they are open.

Since they have a central axis I should be able to point the normals to the outside of that.

So that's one thing that should be not too hard for me to fix up.

thx for the answer :)
Waiting the 3dm from Steph for fix the situation :)

another complaint :)
Seems Moi export to OBJ all objects even "hidden" objects !
Is that normal?

Sounds like a bug in MoI, it should be easy to fix this one up.

One other thing Steph may be interested in - the next beta will also have an improvement to Hide, so that when you show hidden objects you will be able to select which ones you want to show instead of just everything being shown. That should help out a bit for more complex scenes.

I see that those pieces that have different orientations were not actually touching each other, so join would not help out there.

However, everything here is a surface of revolution so I should be able to get all these pieces oriented as you would expect.

Thanks for the file!

Good news :)

Last complaint of the day (night) :)
Is it possible to have an export obj extra "low poly" (a circle ---> quasi a square)
towards the limit! Push the cursor to the fewer polygone

See this little movie
Objects are Moi at different resolution

I should be able to figure out some way to add this in as an option.

I guess what I can do for this is to add an "Angle" box to the advanced settings part of the mesh dialog.

The slider currently is used to set the angle, but it is limited to a range between 35 degrees (for fewest polygons) to 3 degrees (for the highest number of polygons). If you could enter in a particular value directly then you could get something coarser, he probably wants something more like 90 degrees in this case.

Of course you will get really bad looking models when doing this...

Thx for the efforts ! (fewer Polygons)
>Of course you will get really bad looking models when doing this...
Yes but it's for animation near/ far away :)

For the "normals" I will try to explain the Steph problem :)
C4D knows to remake the good "normals" : its the "Backface Culling" function during the rendering
It was disable for show you the the aspect of normals after the "poly transform" in Moi

Why it's a problem? In real time "Backface Culling" makes to lost performance (speed) and create annoying other probs :(

Normals can be also be remove in the good way in C4D before the rendering in but in this case
informations of the "Normal Smoothing" based on the Nurbs objects is lost :(
And that is a pity because the "Moi Normal smooth" quality are very good for simulate the perfect forms of nurbs objects even on Low Poly Object!

It's why if "good Normal orientation" can be made in Moi that will be the paradise :)

But why are the normals lost in C4D upon the flip?

This sounds to me like a bug in C4D - it should not lose the "good vertex normals" when you do a flip, it should just reverse those accurate normals and keep them around instead of throwing them away.

Does it possible to adapt the script "arrow key rotation 3D view" to a selection? :)

When nothing is selected the 3Dview is rotated with the arrow key
When something is selected the selection is rotated with the arrow key (useful in any view!)
/ by the center of gravity of the selection (or by an another point) ?

I suppose yes, but I am some rusted for this little brain sport ;)
Maybe enter somewhere a numeric angle rotation will be also useful
actually 6° can't make 10° :)

Steph answer :)
C4D don't work with "smoothing's normal", only with a global Phong angle parameter smoothing!
So it's a real luck that C4D can even yet recover perfectly Moi's Normal !!! Other 3D prog can't (Hexagon...
So seems that is a C4D bug!

Hi Pilou, currently I don't think there is a way to do this since there isn't a way for a script to get the center of gravity of the selection right now. I can add this at some point in the future but I don't think this will be ready for V1.

Well, if you requie a 10 degree rotation you can alter that script to have a 5 degree or 10 degree rotation instead of 6 degrees.

Is there something that you're doing that requires an exact 10 degree view rotation?
