The invention relates to a high-precision
terrain generation method, device and equipment based on dynamic
paging. The method comprises the following steps: dividing global
terrain data into multi-level tiles, generating multi-level LOD data, and constructing a
quadtree-
hash table two-level index structure; based on an index structure, dynamically calculating an LOD level according to a camera view cone and a predicted viewpoint position, and generating a
paging scheduling
queue according to a priority weight model; asynchronously loading high-priority
paging data in an independent loading thread, and performing
cache management by adopting an LRU strategy; and carrying out real-time three-dimensional rendering on the loaded pages, realizing smooth switching by adopting interpolation transition, carrying out vertex weighted average and texture mixing
processing on adjacent page boundaries, and carrying out cyclic mapping on
longitude boundaries. According to the scheme, the problems of
high memory occupation, low rendering efficiency, loading
delay and the like in large-range high-precision
terrain real-time generation are effectively solved, and the
system performance and the user experience are improved.
