PUBLIC DOMAIN 3D OBJECT DATABASES
FILE CONVERSION FOR USE WITH CAD-3D 1.0
CAD .3D/.3D2 CONVERSION PROGRAM
All of the object files on this disk are in the new CAD-3D
2.0 file format. If you are using CAD-3D 1.0 you will need to
convert these files back to the older file format with the
CONV3D.PRG program included on your disk.
This program is very easy to use:
1. Place the program on a blank formatted disk along with
the files that you wish to convert (you have to do this
procedure in batches, since this disk is filled to the gills
already). Make sure that there is plenty of space on the
disk. The original files are not deleted, and the .3D files
that are created are a little larger than the .3D2s. Your
disk should be less than half full (about 40%) when you
2. Double-Click on CONV3D.PRG
3. Double-Click on the filename of the .3D2 file you wish to
convert. A new file with the same filename, but with a .3D
extender, will be written to your disk.
4. The program will alert you when the conversion is
complete. You may then choose to continue (click on MORE),
or exit (click EXIT) back to the desktop.
NOTES ON MEMORY CONSTRAINTS
For those who own the old CAD-3D 1.0 and a 1/2 Meg
machine, certain compromises will be apparent in loadable
file sizes and/or maximum size of object lists, faces and
NOTE ON THE OBJECTS ON THIS DISK
The Super Extruder tool was used to create some of the
objects, such as the Atari logo with multicolored sides, and
the multicolored flag (created as one object).
One of the objects is actually a raster that was "cut out"
of a Degas picture and converted into a polygon object using an
in-house utility that we're working on. (MICKEY.3D2)
This is a huge object, but it can be animated with PD3DCTL
or CYBER CONTROL without you having to wait around. We're
showing this object as an example of work in progress
-- there are still a number of problems that must be solved
before this technique can work in all cases.
Six of the objects on this disk (NOSE, COBRA, MANTA, POD,
COIL, ARCH) were created by Darrel Anderson with CYBER
CONTROL. These objects are built with the
splined-object-building capabilities in that program.
One of the objects (RIPPLES) was also created with CYBER
CONTROL (by Richard Parker), using the function plotting
capabilities of the program.
The SHUTTLE, LAVI, and F24 objects were built by David
Snyder. It's interesting to note that the Lavi fighter was
