In desktop 3D graphics applications, moving the virtual camera enables the user to view different parts of the 3D scene. In addition to the obvious purpose of ...
by G Wiedenbauer · Cited by 81 — Abstract. In mental rotation tasks, reaction time increases linearly with increasing angular disparity (Shepard & Metzler, 1971).
The experiment reported here was designed to measure the time that subjects require to determine such identity of shape as a function of the angular difference ...
One dimensional shapes have only length: line. • 2 Dimensional or 2-D shapes are plane shapes having length and breadth ; ex triangle, square, circle.
In the mental rotation task, subjects were first taught to mentally rotate (30°, 60°, or 90°) two-dimensional nonsense objects. After.
by A Provost · Cited by 37 — Shepard and Metzler's (1971) seminal mental-rotation task—which requires participants to decide if 1 object is a rotated version of another or its mirror ...
One of the challenges with manipulating 3D deformable objects is that models handling 3D representations typi- cally require a significant amount of data to ...
3D object manipulation is a particular type of 3D object interaction technique [37]. Here we use Bowman's definition of manipulation, which is a task to ...
