Euler Operators for Stratified Objects with Incomplete Boundaries
(The Eurographics Association, 2004)
Stratified objects such as those found in geometry-based systems (e.g. CAD systems and animation systems) can be stepwise constructed and manipulated through Euler operators. The operators proposed in this paper extend ...
History Based Reactive Objects for Immersive CAD
(The Eurographics Association, 2004)
Virtual Environments (VE) allow direct 3D interaction, better perception of shapes and a feel of immersion, properties that are highly desirable for design tasks. Traditional CAD software extensively use WIMP interfaces ...
