terrain size limitations - 04/06/09 11:37
The manual says:
However I asked myself what "theoretisch unbegrenzte Größe von terrain" means exactly and tried it out.
I managed to create a 45*45 grid of chunked terrain with terrain chunk at 32, resulting in (45*32+1)^2 vertices = 2076481 Vertices (at a nexus of 400mb). Fps without any lod or clipping: ~25
This seams to be the limit though, as when I try to create terrain with more vertices I receive the error "bad terrain file format"
I use a dll that uses hmp5.lib for creating terrain.
My question: Is there a vertex maximum for chunked terrain? Or is the limitation given by using hmp5.lib?

Der hochentwickelte Renderalgorithmus entfaltet seine Stärke bei chunked terrain. Beim Laden wird es in quadratische Parzellen geteilt, die ein einem Cache gespeichert werden. Sie werden separat geclippt wenn sie sich außerhalb des View-Frustrums befinden und P in verschiedenen Auflösungs-Schritten je nach Abstand zur Kamera und in Abhängigkeit der Einstellung von terrain_lod gerendert. Diese Methode ermöglicht viel schnelleres Terrain-Rendering und theoretisch eine unbegrenzte Größe von Terrain.
