Detailed Description

The SoLinearProfile class is a node for specifying linear profile curves.

Use nodes of this type if you want to set up profiles that are simply straight lines connected by control points.

Member Function Documentation

SoType SoLinearProfile::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

void foo(SoNode * node)
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoProfile.

const SoFieldData * SoLinearProfile::getFieldData (void) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoProfile.

void SoLinearProfile::getTrimCurve (SoState * state, int32_t & numpoints, float *& points, int & floatspervec, int32_t & numknots, float *& knotvector) [virtual]

Return points and knotvector of the state.

Implements SoProfile.

void SoLinearProfile::getVertices (SoState * state, int32_t & numvertices, SbVec2f *& vertices) [virtual]

Return vertex set of state.

Implements SoProfile.
