is a shortened form of a prim
's "surface". In LSL
this is commonly referred to as side
, though there are some differences. In normal 3D usage, a face
is a single polygon
For example, a newly created
sphere has one face: the outside. It is the only surface that can be seen from any camera
angle and that can have a texture
applied to it so it is referred to as face 0 (zero).
A sphere that has been hollowed out has 2 faces: the outside (face 0) and the inside (face 1).
Other face possibilites exist, including the edges of a cut, hollowed out prim, and other such possible surfaces. See side
for a list of faces available on an axis
-aligned cube (including hollow and cut adjustments).
