.obj -> .sur converter

Please tell me, how to properly search “Opposite” triangle in convex hull mesh?
Now i’m looking for the intersection from barycenter, in the direction of the inverted normal, and it seems to work.
I have found differences in the choice of opposite triangle, in different exporters.
1. Vanilla exporter, work approximately as my, but sometimes it hits in the neighboring triangle.
2. msSURExporter v1.2 seems looks for a triangle, with the maximally oppositely normal, without position check.
3. May be i’m most to draw a line, from the barycenter, through the center of the mesh, and find the intersection with this, i‘m doubt it. -
From memory I use the most away faced normal I can find. I can look it up if you need it. Which brings me to my next question: Why do you want to know this?

I’m writing a command line converter in C++, which using more model fixes, and .ini files for best usability.
Now supports - import from .cmp/.3db/.mat/.ms3d, export to .cmp/.3db/.mat.
Also, i’m need for fully correct .sur files, i’m working now for this.
I would like a good understanding, for what is needed and how they must be made the opposite triangles, for create correct code. -

Perhaps one day the FL community will get out of the stone age and stop using the trash heap that is MS3D. I mean, there’s already a 3ds Max exporter that works much better.
-
I like the stone age… its free… and it does pretty much everything you need if you use the correct plugin versions.
Certainly the stone carvings are not that easy to be done… but well… there are plenty of free and compatible tools that are easy to use.

MS3D and all related plugins are really trash, but least people have either enough money, a company or whatever license for 3dsMax. And it also excludes users of programs like Blender.
Would it be a neutral converter as Schmackbolzens obj-sur-converter is, then everyone could do it with whatever program they want. That, in my opinion, would be the best solution for every modder.

I absolutely agree that an importer would be better than a plugin (though we’d need a richer format than OBJ to have all relationships and data, FBX being the most likely candidate), but until then 3ds is still better.
MS3D wasn’t free for the longest time and that didn’t stop anyone (and no, people did not buy it). On top of that, 3ds Max is free for students, all you need is a student email address.

I have already the Max plugin. But why not see how this one works ?

Im too old for becoming student again… all the alcohol… all the parties

Actually, you dont need to be a student, or have a student email. You can gain access to a educational licensed version by specifying your a ‘mentor’…any email address will do.
However milkshape has some definite benefits over 3ds max, most importantly its size (25mb vs 6-8gb) 3ds is fine if your planning on doing tons of model creation, but if you just need to convert model formats then its serious overkill -
Personally I’d not recommend to do any sort of conversion with milkshape due to how limited feature support is there, namely vertex color and transparency, multiple uv maps. Even basic stuff like vertex normals aren’t well supported across formats and has a tendency of screwing up your stuff. If someone wants to make a good importing/exporting tool they’re better off converting between collada and FL formats. Collada has all the necessary features for FL models and is fairly extensible even within its validation schema.

From what I got you would like to have settings for each file. I can write that so that e.g. mass convert takes this into account. If there is demand? I don’t know how many still use this tool.
-
I write a complete solution, without any clicks, with automatic binding of all vertex, parts, hardpoints offsets in .cmp and .sur files.
I need the ability to quickly correct any problems, and make new features without waiting for the another developer.
The only complexity moments for me were - bits-section and convex hull.
I would be grateful for the help by source code, primarily msSURExporter V1.3. -
The feature with reading certain parts from cmp files was planned, but I never started it since not many people seemed to need it. Using the model itself was deliberately not done, since you need special collision models.
If enough people ask I would be willing to extend this tool further, but so far this seemed not to be the case.
I think you underestimate what it takes to write correct sur files, but we will see.

Thanks Adoxa!

First of all, you need to create the correct information about the parts in .cmp, before parsing by .obj -> .sur converter. There are problems with other exporters, if part is ‘Rev’, ‘Rris’, or chained over other (not ‘Root’) part.
Also, I have implement the automatic connect hardpoint meshes from separate .ms3d file.
I try to exclude such routine work. -
Is there anything known about the lag issue of surs when colliding with them?
I seem to have the issue on new station models no matter if I use the obj2sur converter (latest version) or the 3ds max tools.
It also does not seem to matter if I let the tools run their job on the model (cmp version), a detail reduced version (rough shape) or even a version which only consist of purely convex shapes.The lag starts when forcefully colliding with the station after some time. NPCs also seem to cause these kind of issues in rare occasions.
I’ve read that the lag issue is know… and fixed but… it still happens… dunno.
