Three-dimensional cursors for volume-rendering applications
Yuen-Wah Hui, Wai-Yin Ng · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
An interface metaphor is proposed for developing a 3D cursor for volume rendering applications. The metaphor, Luminous Gel, is a material for moulding 3D cursor. We have successfully demonstrated that such a cursor's location and spatial relationships with volume- rendered 3D objects are readily perceivable. Editing tools made in Luminous Gel have also been developed, which are useful as effective positioning tools for functional operations and inspecting devices for features exploration and scene understanding by enabling immediate depth perception and object highlighting. The editing tools have also been further elaborated for performing planar and curved sectioning directly and naturally.
