This paper describes a method for manipulating a threedimensional object without considering conventional three independent orthogonal views. We apply the direct manipulation to o...
Shading has a great impact to the human perception of 3D objects. Thus, in order to create or to deform a 3D object, it seems natural to manipulate its perceived shading. This pape...
The early architectural design stage is a typical example where traditional design tools such as sketching on paper still dominate over computer-assisted tools. Augmented reality ...
Object alignment is one of the basic operations in drawing programs. Current solutions provide mainly three ways for carrying out this operation: either by issuing an alignment co...
