Abstract

Picking is an essential task and an interaction technique in any interactive graphics application. In the field of VR-like systems, conventional point and ray-picking algorithm is still widely used. The algorithm gains its performance by utilizing ray intersection checks to minimize the number of costly nearest point calculations. To reduce these costly operations on the precise VR world, we introduce an algorithm that performs ray intersection test during user interactions. The algorithm is gaining its performance by reducing these checks dramatically compared to the naive approach where the checks are carried out with each 3D cursor movement. The user can also query the system to see how they can perform a specific task. In this paper I wish to illustrate how the point and ray picking shape algorithm
works and helpful for the effective virtual object picking process.
