Abstract:Placing probes for environment maps is a tedious and time-consuming task for current game developers. In particular; locating the significant places for reflection requires the artists to manually scan through a whole game level. Even then; probes may wind up being too similar and have to be cleaned up manually later on. Furthermore; the whole process needs to be repeated when the content changes.

We propose a novel algorithm which assists the artist when placing environment map probes. Based on the original game content; we produce a set of candidate locations for inspection by an artist. By setting a few parameters like sampling density and aggressiveness of probe elimination; the overall number of generated sample probes can be easily adjusted. All of this requires only a short pre-process which can be done using the available in-game renderer. From the generated sample set; the artist can decide which locations are important; add or remove probes manually and adjust the placement to account for supplemental; content-specific parameters. Our initial probe placement; together with additional information computed by our algorithm; allows the artist to place probes more efficiently. Early user testing indicates that the total time can be reduced by up to half a day for a single game level.
