A survey of level of detail support in current virtual reality solutions
The technique of Level of Detail (LOD) offers a powerful method of reducing the computational burden of a virtual reality (VR) system. As a result, it represents a valuable and important facility which one would expect to find in all serious VR graphics systems. This survey aims to present many of the rendering engines commonly employed in state-of-the-art VR solutions and details the degree of support which these systems provide for LOD. The investigation reveals a significant lack of support for this facility over the range of packages reviewed. Consequently, a call is made for improved LOD support in future VR products.
