An Efficient Ray Tracing with LOD Control by FOV on Large HD Display System
Details
In this paper, a fast ray tracing technique with LOD (Level-of-Detail) control for a large super-high-resolution display system is proposed, which considers human's field of vision (FOV). In the proposed method, according to the level calculated by FOV, pixels are determined through which rays are emitted from viewpoint. Also emitted rays are limited by generation (numbers) of reflection/refraction with objects. Reducing rays which go through pixels with no/less attention for the user, the proposed method balances fast computation with image quality for the user.
