For such an incredible (and potentially complex) application, 3dmiX doesn’t seem to come with much in the way of documenation. Grep the /boot/beos/documentation folder, and you won’t find a single reference. That’s because it appears in the docs under a different name: 3dMixer. If you’re on a BeOS machine right now, this link will take you there:
file:///boot/beos/documentation/User’s%20Guide/Rel ease Notes/3DMixer/3DMixer.html
You’ll also find documentation of the app in the BeOS Bible R4.5 Update pages (see the Demos section).
Finally, BeOS Central offers a mini-site dedicated to covering the ins and outs of this remarkable tool, including a full tutorial.
