MDX Squisher

05-20-2006, 04:20 PM

This program makes Warcraft III MDX files, once saved in
the MPQ, 60 to 70% of their original size. To use it,
just run the program, click the button, and choose your
file.

Repeatedly using this program on an MDX and then editing
it again may result in a loss of quality, so you may want
to avoid overwriting your original files.

The thumbnails are examples of how it affects file size and a side-by-side comparison of a squished and unsquished knight, showing that you can't see a difference.

Tim.	So it merges nearby verts or something? How exactly does it 'squish' the file to conserve space?

emjlr3	has this been tested at all and found virus free/working, this could be useful

Guesst	It zeros the least useful bytes, and then MPQ compression turns that into a lower file size. A lot of data (normals, for example) are stored with a lot more detail than you would ever see. The program zeros the two lowest-value bytes for a bunch of floats. Specificially, it goes after vertices, normals, tvertices, movement, rotation, and scaling.

Rao Dao Zao	Sounds good; usually I snap to grid anyway on the geosets, but animation data could do with it in a lot of cases. Will have to examine this. EDIT: Preliminary tests show no apparent loss of quality, so there's no reason not to approve this.

Tim.

In that case I approve it on behalf of the art section, however please make sure to include the following so that it meets the tool requirements:

Jazradel	This tool has incredible potential. I'm gonna have to fun a few mroe tests to see how well it works, but it's looking good so far.

nooK	Tested it on Black_Stan`s models and it screwed up some small parts of them. Don´t know if it works better on other models. Nevertheless good tool
