Improvement on dynamic tiled terrain rendering algorithm in libMini
Authors: Liao Mingxue, Xu Fanjang, He Xiaoxin
Abstract
As an open source library for large-scale terrain rendering in a continuous LOD high field, libMini takes a top-down method for static terrain rendering and achieves good performance. However, it uses the same top-down method to render elevation and texture for dynamic terrain. The method consumes a few seconds to update dynamic terrain and thus does not meet real- time requirements for rendering and leads to possible holes and gaps between adjacent terrain tiles. A millisecond-level real-time bottom-up libMini-based algorithm is proposed to render dynamic terrain while a method is presented to blend holes and gaps produced during the process of rendering dynamic tiled terrain.
