This node specifies a piecewise-linear curve that is used as a profile for either a trimming patch of a Nurbs surface or for the bevel of
SoText3. The
index field indexes into the current profile coordinates (specified
in an
SoProfileCoordinate2 or
SoProfileCoordinate3 node). If the last value of the
index field is
SO_LINEAR_PROFILE_USE_REST_OF_VERTICES (-1), all remaining coordinates in the current coordinates will be used, starting with the coordinate after the previous index (all coordinates will
be used if
SO_LINEAR_PROFILE_USE_REST_OF_VERTICES is the only value in the
index field). For example, if
index contains the values
[2,0,-1] and there are 4 profile coordinates (0-3), it is as if the
index field contains
[2,0,1,2,3].
