NAME SoProfile SoProf SO_PROF_ { abstract base class for all profile nodes }
INCLUDE nodes/SoProfile.h
DESC {
This node is the abstract base class for all profile nodes, which
define 2D curves. A profile is not itself geometry, but is used to
change or delimit the geometry of something else. For an \cSoText3\.
node, the profile determines the cross-section of the side of each
text character. For an \cSoNurbsSurface\. node, the profile is used to
specify trim curves for the surface.
\p
The current profile state can consist of one or more profiles, each of
which can be made up of one or more instances of \cSoProfile\.
subclass nodes. Each profile node specifies (in the \vindex\. field) a
set of indices that refer to the current set of profile coordinates,
specified using either an \cSoProfileCoordinate2\. or an
\cSoProfileCoordinate3\. node. No profile curve should intersect
itself or another profile curve.
\p
Profiles are part of the state, just like all other properties. The
state contains a current list of profiles. Depending on the
\vlinkage\. field, a profile can clear the list and begin a new
profile, begin a new profile at the end of those already in the list,
or append to the last profile in the current list. Note that when
appending profile B to the end of profile A, B must begin at the same
2D point at which A ends.
}
ENUM Profile {
START_FIRST "Start a new profile and remove any existing profiles
from the current list",
START_NEW "Start a new profile and add it to the current list",
ADD_TO_CURRENT "Add to end of the last profile in the current list"
}
FIELD index { Indices into profile coordinates. }
FIELD linkage {
Specifies connectivity of profile curve with respect to profiles in
current list in state.
