Hello !
Ok, so here's how I added collisions to my model (the road I posted earlier).
When I started to look at collisions, I tried to use Collision Adder, but it didn't seem to work exactly the way I expected.
That's why I decided to have a look at the source (thank you so much for including it) and try to understand how it works.
After some time, I thought it was related to the way normals were handled. As I understand it, the program copies the model vertice and normals, as well as the skin file triangles, to make a custom bounding box.
The wiki (and that's also what I observed on a Blizz model) says there's one surface normal per triangle for the bounding box, and not 3 like the ones that go with the model vertice.
So I slightly edited the program to make it fit : one normal per triangle (so their number was divided by 3), and I added cross product + normalize to calculate the values for each of them using the existing functions.
Of course I include the modified main.cpp as well as the exe.
Be indulgent, C++ (and M2 actually) is like a whole new world to me. It took me time to figure out how to compile the original program, adding my 4 lines at the right place, etc.
Nonetheless, it looks like my changes work here (and I'm the first one surprised they do), so I post them. Hope it'll be useful.
I tested the program on 2 models only, since I don't have many of them. Of course, on both it worked.
Feedback is welcome :)

I'll give it a try when I've got some 3d modelling programs installed again, thanks!

wow, checked on my 24 models . 100% fine work

Thanks for testing, and I'm so happy it also works on other models than mine ^_^

On one of the models not added collision
As should be:
C:Documents and SettingsUser>D:tempCollisioncollisionadderCollisionAdder.e
xe D:tempCollisioncollisionadderEnclaveWallfragment01.m2
Loading Model D:tempCollisioncollisionadderEnclaveWallfragment01.m2
Loading Skin D:tempCollisioncollisionadderEnclaveWallfragment0100.skin
Saving Changes
As happens with bugged? model:
C:Documents and SettingsUser>D:tempCollisioncollisionadderCollisionAdder.e
xe D:tempCollisioncollisionadderEnclaveWallpost.m2
Loading Model D:tempCollisioncollisionadderEnclaveWallpost.m2
Loading Skin D:tempCollisioncollisionadderEnclaveWallpost00.skin

Missing line "Saving Changes".
collision in model also not added.
(The model I have added below)
this my 31th model (of 100-120)
I can give you more models that do not work in Collision adder (via Private Message)
-
Mmh, could you send me your mdx for this model ? It would be really easier for me to see if there's something different from the one I use, and why one of them works and not the other.
Are there lots of models that don't work for you ?
-
does not work about 20-40% models.
oh mdx... i have only mdl((MDX analog, which can be edited via Notepad) source. now take a search.
up1: Attach two MDL models in the archive
-
Thanks, that was really helpful :)
I don't get why for the moment, but I have a simple fix :
If number of vertice < number of faces in mdl/mdx (you have both numbers in mdlvis in the upper right corner of the vertice editing mode), the conversion crashes.
So you can take the model, copy a free vertice (on both models you have one in more or less the center of the grid), and paste it until you have more vertice than triangles. The the converter doesn't complain and it goes ok.
I'll try to see if I can correct that better.
(And btw, I really like the shape of the fence you sent ^^)
-
hmm, when converter was crashes. I copied (duplicate) geometry in model, while number of triangles was still several times more (than vertices). But a model successfully converted. (Similar problems were encountered only in models with 2-3k triangles)
or something I do not fully understand.
-
I tried to solve the problem yesterday night but I still haven't a clean solution to correct it. I will try again though, when I have a new idea.
Do you still have some models you can't convert at all, even with the "add more vertice" trick ?
-

I see no problem there.
-
O_o
That one is weird... On Vel's model I have a converter crash with my modified version (but not with the original one : the collisions are then saved but not correctly created).
There's definitely something I don't get :)
-
You may want to look at the stacktrace of the crashed application as well as add debug output to see in which line the problem is.
-
I just cleared the code up a bit out of boredom.

Clean code, guys!
-
Wow, thank you :)
-
lol, I feel bad, I should have seen my error (looks like I forgot to change nInd to nTri a few lines up) -_-
Thanks again.
I have a noob question... g++ complained with the include using < > (it couldn't find the files) and I had to change to " " to compile... I tried to read about the difference (quick googling), but I'm not really sure if it changes something in the end or not... Is it really bad to use one instead of the other ?
-
" is relative to the current directory. < is relative to the search path specified to the compiler, usually with -I.

Ok, thank you :)
I upload a compiled version (no changes).

Thank Mjollna, you're the best!
During the day, I'll look at all of its remaining models.

up1: checked for 12 models (which had not previously worked) - on a new version works
-
You'll have to thank Schlumpf on this one, not me :)
I just uploaded a compiled version.
-
We all should thank schlump... Thanks Schlumpf ;)
-
Sorry if this is just a stupid question, but by adding collision to a model.. like a character model, makes it so, that one cannot simply just walk thrugh him anymore?
-
no, collision on character needs to interact with the world.
(Gnome can get into the fireplace (http://www.flickr.com/photos/azyxa/4141714596/sizes/l/in/photostream/)(link) in the tavern in Goldshire, but a human can not.)
-
Characters / units are not checked for collision against each other. They do have collision, else they could not collide with the world around them.
Also, collision cannot be animated which would be really odd for more than a basic box used for collision.
To enable collision between units one would have to modify the client in depth, thus being pretty much impossible.
You can do pseudo collision for unit movement server side though. This would be odd for players though as not known by the client. For DotaWoW, they did collision for NPCs being regarded in path finding.

One Stupid Question ...
What About Collision Remover ? or do you know any way how to *fak* up with collisons ?

Oh i was wondering its something around bounding box
Thanks for this
i tried my model (quicksand) and all worked well

May someone reupload latest compiled version please? (Links are down)

yes plz these models http://www26.zippyshare.com/v/21759497/file.html (http://www26.zippyshare.com/v/21759497/file.html" onclick="window.open(this.href);return false;) don't work with Collision Adder I have
-
Does anybody still have the latest compiled version of this app?
It would be very usefull to have one the one that can handle the Camera collision as well the normal collision.
-
Sorry about the necro, but I don't know much of anything about modeling or that for WoW.
If I were to use this on the player models, would that prevent players, mobs, etc... from walking through each other or are collision boxes set to only work for objects?
-
They already have a collision bounding box. Figure from that.
(It does not. Not everything collides with everything.)

Ah, alright.

Necro-update :3
Re-up of the collision adder at a more stable URL (the exact same file) :
http://gaming.mjollna.org/static/docs/collisionadder_2011-10-27.zip (http://gaming.mjollna.org/static/docs/collisionadder_2011-10-27.zip)
It should be ok for LK files, but probably not for newer versions.
If you want to compile, you'll need Tigurius' now antique M2 files.
Miraculously, the mediafire link still works : viewtopic.php?f=59&t=829 (http://modcraft.io/viewtopic.php?f=59&t=829" onclick="window.open(this.href);return false;)
Why have Eluo's internal links to resources disappeared ? It's such a loss, even though there are more recent programs for lots of stuff now, some are still interesting, and show some code to people who want to start.
Edit 2017-04-21 : attached the script to this post and updated link again.
Edit 2019-02-20 : updated the link again (url changed on my website)

Problem with the root. Thats why we prepare a move in the moment.

Oh ok, so files are still there, but not available for the moment ?
... "moving" ? You plan to migrate the forum elsewhere ?
