.PP 
.SS "\fBSoType\fP SoShape::getTypeId (void) const\fC [virtual]\fP"

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

.PP
.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.

.SS "SbBool SoShape::affectsState (void) const\fC [virtual]\fP"
Returns \fCTRUE\fP if the node could have any effect on the state during traversal\&.

If it returns \fCFALSE\fP, no data in the traversal-state will change from the pre-traversal state to the post-traversal state\&. The \fBSoSeparator\fP node will for instance return \fCFALSE\fP, as it pushes and pops the state before and after traversal of its children\&. All \fBSoShape\fP nodes will also return \fCFALSE\fP, as just pushing out geometry data to the rendering engine won't affect the actual rendering state\&.

The default method returns \fCTRUE\fP, on a 'better safe than sorry' philosophy\&.

.SS "void SoShape::beginShape (\fBSoAction\fP *constaction, const \fBTriangleShape\fPshapetype, \fBSoDetail\fP *constdetail = \fCNULL\fP)\fC [protected]\fP"
This method is used to generate primitives for a shape\&. It's typically called from a node's \fBgeneratePrimitives()\fP method\&. If you have your own shape and want to write a \fBgeneratePrimitives()\fP method for that shape, it's probably a good idea to take a peek in the \fBgeneratePrimitives()\fP method for a similar shape in Coin\&.
.PP
\fBgeneratePrimitives()\fP can contain several \fBbeginShape()\fP/endShape() sequences\&. \fBshapeVertex()\fP is used for each vertex between \fBbeginShape()\fP and \fBendShape()\fP\&. For instance, to generate primitives for a triangle you'd do something like this:
.PP
.PP
.nf
SoPrimitiveVertex vertex;

this->beginShape(action, SoShape::POLYGON);
vertex.setPoint(SbVec3f(0.0f, 0.0f, 0.0f));
this->shapeVertex(&vertex);
vertex.setPoint(SbVec3f(1.0f, 0.0f, 0.0f));
this->shapeVertex(&vertex);
vertex.setPoint(SbVec3f(1.0f, 1.0f, 0.0f));
this->shapeVertex(&vertex);
this->endShape();
.fi
.PP
.PP
Note that the \fBSoPrimitiveVertex\fP instance can simply be placed on the stack and not allocated\&. \fBSoShape\fP will copy the needed information when you call \fBshapeVertex()\fP\&.
.PP
Before calling \fBshapeVertex()\fP, you can set extra information for the \fBSoPrimitiveVertex\fP, including normal, material index, and texture coordinates\&.
.PP
This method is slightly different from its counterpart from the original Open Inventor library, as this method has an \fBSoDetail\fP as the last argument, and not an \fBSoFaceDetail\fP\&. This is because we accept more TriangleShape types, and the detail might be a \fBSoFaceDetail\fP or a \fBSoLineDetail\fP\&. There is no use sending in a \fBSoPointDetail\fP, as nothing will be done with it\&.
