User interfaces for three-dimensional geometric modelling
A. Robin Forrest · 1987
One of the biggest obstacles to the wider adoption of geometric modelling systems for three-dimensional objects is the relatively poor state of user interfaces. In geometric design, two forms of interface are required: one which permits rapid evaluation of the three-dimensional nature of an object and its relationship with other objects, and one which permits precise positioning and shaping of an object. Many systems provide one or the other but fail to provide both. The paper will address issues relating to both forms of interface, particularly in the context of current display technology.
