Yes, yes! Definitely keep up the awesome work. I'd like to be able to select all edges and use the bevel tool. I tried last night but it didn't seem to work and created some strange geometry.

Also: is there a way to have a realtime scene preview?

Hm. Well...this is what I got. I extruded a cube until I had the shape I wanted, then selected all edges and chose bevel. I hope I'm not doing it wrong:

btw, bevel on a normal cube works great! Normally, when I use the bevel tool in, say, Blender, I use 2 "iterations" or so...is this possible (tried it by repeating the bevel command but couldn't get the results I wanted)?

There are definitely problems with this mesh.

Oops, that is my "results from the bevel tool" mesh, not the original mesh The original mesh is a cube that's been extruded down, then left, then up, then to the right, almost making a sort of square shape. It was all one solid mesh before I used bevel, I swear

Could you post an example, step 1,  step 2?

Yes, here we go:

Here's (left to right) 1, 2, and 3 "recursions". You can choose as many as you want but I hardly ever use more than 2:



And here we are zoomed in on number two, the middle cube:



So basically it is just splitting the bevel into more faces to round it out a bit. Depending on how close the viewer is to the object, this can be important.

PolyMesh uses the same tools and representations than the triangle mesh editor, so there is little I can do on that subject, but what do you have in mind ?

Just curious. For complex scenes it's difficult to guess where your extrusions are going to end up (speaking of the overall scene) sometimes. So I was hoping for a "refresh" button that would update the scene without having to close the polymesh editor and re-open it. But it's not a big deal for now.

Just out of curiosity...
is it possible to have the "smooth" as a modifier like bend or scale?
Not to animate it - while that might be nice - the intention is more to model something and just smooth it while rendering.
It´s also nice to be able to work on the model again without having a copy.

In one sentence:
Develope the Polymesheditor furthermore, but have the smooth only as a modifier - execpt a preview option in the Trimesh/Polyeditor.

Marc: here is where the bug comes from. Physically speaking, beveling consists in smoothing/cutting angles on the shape edges. However, triangle/quad meshes do happen to show flat edges. Those edges that run in the middle of your square shape. Or more specifically, take a cube, extrude the top. The edges created where the top face was previously are flat. There is no mathematical meaning in beveling them. You can't flatten something that is perfectly flat! Consequence: division by zero and vertices are sent on the moon.
When that happens, logic takes over maths and you do something geometrically sound. That's why bevelling a flat mesh works (and my version is probably more locigal than Wing's is, for once...). But I forgot this particular situation.

Vidiot: It seems to me (but I might be wrong), that you're forgetting about smoothing method. In AoI, use the Smoothing Method. Approximate option is flexible, you can have smoothing between 0 and 1 for every vertex and edge. Smooth mesh -Catmull-Clark- is not intended to provide the final smoothed mesh, but to refine the mesh through subdivision as you're working on smaller details. That's a big difference with modelers that don't do "auto-smoothing", like  Wings.

0.41 out, as announced in the AoISP open discussion forum. This fixes all the bevel function "gliches" (and boy there were some!).

Marc: you can do successive bevel using the bevel tool and dragging the mouse as many times as you wish (though two is probably enough). Here is a cube extrude twice (much as you'd like two) and bevelled twice with all edges selected:

Hmmm, check out this one, I beveled twice. I guess it's possible to "go overboard" with the bevel, and I'm not sure this is a bug, but just in case:
