“Before terrain generation, terrain nodes are preprocessed. Then, based on the camera’s previous distance, a decision is made on whether the quadtree should be updated. The quadtree nodes are then passed to the GPU, where operations such as view frustum culling or occlusion culling can be performed.
Additionally, STITCH is processed on the GPU. The camera’s distance and the terrain’s complexity determine the LOD of the mesh”, explained the developer.
