Planetary Marching Cubes: A Marching Cubes Algorithm for Spherical Space.

There is a growing interest in digital games with user-generated content. Games with user-generated content usually involve terrain editing and marching cubes is a popular algorithm that permits a dynamic terrain. On the other hand, there is also growing interest in games with a planetary theme. Hence, a question is asked on whether can marching cubes be used to generate a planetary terrain. This study investigates how to adopt the marching cubes algorithm in a spherical space, specifically, for generating a planetary terrain. The result is the proposed planetary marching cubes, which compared to previous methods, could generate more complex terrain features while retaining smooth surfaces.
