Need a tester(s)

[GhostWolf]

I saw for the first time MDX Squisher, and figured I could do the same thing except more complete (the original only covers a part of the data).
In addition to this, I want to remake what I did years ago with MDL Optimizer, which removed useless animation keyframes.
If it will work fine, I'll add support also for M3 models.

I need a little test for the following files, since I don't have WC3.
The idea is to make two identical maps, import each model version to each map, save them, and see if there's a difference in the map file size.
The second part (assuming v2 is actually smaller) is to check if the model works fine in-game.

Note: currently it only runs on a small subset of the data (namely, the geosets), if it works, I'll add all the animation data.

Thanks.

Here you go

EDIT: Doesn't work in game.

Yeah that code failed badly.

Right now the floating point precision is working, I'll remove useless keyframes next.

Any ideas for other size optimizations?

You could probably have some kind of mesh simplification algorithm which merges nearby triangles if they are very linear. That might not be the best way to describe it but basically it removes triangles from the mesh if they represent a very shallow curve (appear almost flat). Although I am guessing the actual model editing programs should do this to some extent but I do not know.

Ok, now the keyframes also get removed.
A threshold to what keys are "equal" to each other can be specified.

Attached an example, it uses this model, I used 0.001 as the threshold.

The next step is to add M3, and then somehow make an executable out of this (Lua code).

/Edit
Added also an option to force bezier/hermite keys to be linear.

Ok, the MDX part is complete, the M3 part is still under work, but already compresses models.
