QuickDraw 3D v1.6 is known to not work in SheepShaver; therefore, all
of the (available) earlier versions of QD3D are being offered for
download, as alternatives.

* * *



The first 3 downloads are .sit-compressed folders of the QD3D install
folders on the universal-installer CD-ROMs for MacOS 8.x.

The 4th download is a folder containing (2+2=) 4 disks for the v1.0.3
and v.1.0.6 installers that were distributed on 3.5" floppy disks with
System 7.5.3 (and possibly also the System 7.5.5 update).

The 5th download is a folder containing the system extensions (without
an installer) for v1.6. As far as I can tell, v1.6 was the final
version of QD3D. I have no idea how (or if) it was distributed.

The 6th download is a folder of the extensions (not an installer)
experimental v1.6e1 made 1998-1999, I know nothing about it yet other
than it is different.

QD3D v1.5.4 appears (separately) on the MacOS 8.5 and 8.6 installer
CD-ROMs

QD3D v1.5.3 appears (separately) on the MacOS 8.1 installer CD-ROM

QD3D v1.5.1 appears (separately) on the MacOS 8 and System 7.6.1
installer CD-ROMs

QD3D v1.0.6 must've appeared somewhere between System 7.5.3 and 7.6.1,
so maybe the two QD3D installation disks were included with the System
7.5.5 update.

QD3D v1.0.3 appears on a pair of separate System 7.5.3 installation
disks.

QD3D v1.6 doesn't appear (separately) in any of the MacOS installer
CD-ROMs, but maybe it's included in the MacOS 8.6 update and I missed
it.

QD3D v1.6e1 was distributed on a game CD in 1999ish. Uploaded by
SkyCapt.

To use the aforementioned downloads, you'll need to add the downloaded
file to the SheepShaver shared folder (or somehow transfer it to a
physical Mac), decompress the .sit file (probably with Stuffit
Expander 5.5), and use the installer (if present) to add the system
extensions to a particular (virtual or physical) disk volume.

IMPORTANT NOTE:

Mac installers will never downgrade the versions of anything, so if
you need to install an earlier version, then you'll need to either use
the Extensions Manager control panel to disable all of the QD3D
extensions (4 or 5 of them) and restart, or you'll need to find them
in the System/Extensions folder and delete them (or move them to some
folder for safekeeping, if you often need to switch between QD3D
versions).

Compatibility
Architecture: PPC

All of the QuickDraw 3D versions older than v1.6 should run in the
emulator [SheepShaver][1]. The oldest versions of QD3D were
distributed with System 7.x and the minimum OS is sometimes listed as
System 7.1.2. (However, QD3D only works on PPC Macs, so who in their
right mind would keep running System 7.1.2 on a PPC Mac?)

QuickDraw 3D was a rapidly-growing technology in the late 90s, so the
few apps that took advantage of it sometimes didn't have forward or
backward compatibility with later or earlier versions of QD3D (which
is another reason why these downloads are being made available). If
you're struggling to get a particular (vintage-Mac) QD3D app to work,
you may have to experiment with different QD3D versions to find the
perfect match.

If the software requirements for a particular app specify a particular
version of QuickDraw 3D, that may be the only version of QD3D that
works correctly. With most generic specifications, it's assumed that
the listed version of something required is the minimum version, but
with QD3D, that assumption may be incorrect. In other words, later
versions may not work, so don't assume that they will.
