Resumen
Although a thoroughly researched topic, terrain rendering still presents challenges. For instance,
many applications rely on accurate visualization of highly detailed and vast terrain, requiring
the efficient use of both GPU and CPU in order to provide real-time rendering. Additionally, the
increased availability of high resolution global coverage elevation datasets demands rendering
systems capable of accounting for the shape of the planet. Even though previous techniques
are capable of rendering such datasets, most target visualization only and do not account for
interactions between the terrain and simulated objects. Therefore, in this work we present
a rendering technique for spherical terrains that is capable of visualizing extremely detailed
terrains while also supporting interactions with simulated objects. We adapt a continuous levelof-
detail technique to the spherical domain and employ procedural generation techniques to
produce sub-meter elevation data at run-time.
