Position and rotation

Like for other data types, those probably correspond to handles for runtime editing.

x, y, z are oriented the usual way (z+ = forward, x+ = left, y+ = up)

Position is in world units (decimeters). Rotation is in degrees, trigonometric.

Sound pitch

Actually a playback speed multiplier. Other multipliers specified in the OSGr.

Radii (SPHR)

What do they correspond to? Is the following correct?

• r < rmin : volume = "sound volume"
• rmin < r < rmax : volume = "sound volume" * (rmax - r)/(rmax - rmin)
• r > rmax : volume = 0

Please confirm. geyser 15:56, 26 January 2007 (CET)
