Résumé:
animation 3D pour les novices
Abstract:
We present lessons learned from developing Alice, a 3D
graphics programming environment designed for
undergraduates with no 3D graphics or programming
experience. Alice is a Windows 95/NT tool for describing the
time-based and interactive behavior of 3D objects, not a
CAD tool for creating object geometry. Our observations and
conclusions come from formal and informal observations of
hundreds of users. Primary results include the use of LOGOstyle
egocentric coordinate systems, the use of arbitrary
objects as lightweight coordinate systems, the launching of
implicit threads of execution, extensive function overloading
for a small set of commands, the careful choice of command
names, and the ubiquitous use of animation and undo.
