[comp.graphics] 3D Rotation Techniques demo available

chen@apple.com (Michael Chen) (11/22/89)

People interested in interface techniques for 3D rotation might want to 
download 2 demo programs I have posted in comp.binaries.mac. (Subject 
heading is "Virtual Controllers Demo). The virtual controllers are 
described in more detail in the paper "A Study in Interactive 3-D Rotation 
Using 2-D Control Devices" by Michael Chen, S. Joy Mountford and Abigail 
Sellen published in the ACM Siggraph '88 proceedings (Volume 22, Number 4, 
August 1988).  The application "Rotation Controllers" allows you to 
compare the five controllers at the same time.  The application "Rotation 
Experiment" implements a version of the rotation experiment described in 
the Siggraph paper.

Both applications will run on any configuration of Mac II, IIx, IIcx or IIci.
"Rotation Controllers" will also run on the SE/30 though screen space will
be a bit little cramped.

The programs are also via anonymous ftp to apple.com.  The path of the 
file is pub/dts/mac/hacks/Virtual-Controllers.hqx
