Selection Techniques for Dense and Occluded Virtual 3D Environments, Supported by Depth Feedback: Double, Bound and Depth Bubble Cursors
Daniel Alejandro Winkler Rosa, Hubert Hoffmann Nagel · 2010
In 3D Graphic Environments the selection of an object can be hampered by other objects. This occurs when the object becomes occluded by others. The probability of this happening is high if there are many objects in the scene. Over the years, this problem has been addressed by developing various techniques of selection, in order to provide a good mechanism to manipulate objects in a 3D virtual environment. These techniques have been evolving as they solved the problems of their predecessors. Although the third dimension is the distinguishing characteristic of these environments, the best among them does not take depth feedback as an important factor. Therefore, this document addresses this deficiency through the creation of three techniques based on that feedback.
