Additional Inherited Members

The SoResetTransform class is a node type which makes it possible to 'nullify' state during traversal.

SoResetTransform is useful for setting up geometry in the scene graph which will not be influenced by the transformation nodes before it during traversal.

enum \fBSoResetTransform::ResetType\fP

The different options for what to reset.

Enumerator

TRANSFORM

Reset current model transformation.

BBOX

Reset current bounding box settings.

SoResetTransform::SoResetTransform (void)

Constructor.

SoResetTransform::~SoResetTransform ()\fC [protected]\fP, \fC [virtual]\fP

Destructor.

\fBSoType\fP SoResetTransform::getTypeId (void) const\fC [virtual]\fP

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.

Reimplemented from SoTransformation.

const \fBSoFieldData\fP * SoResetTransform::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP

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

Reimplemented from SoTransformation.

void SoResetTransform::doAction (\fBSoAction\fP *action)\fC [virtual]\fP

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

void SoResetTransform::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

void SoResetTransform::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoNode.

void SoResetTransform::getBoundingBox (\fBSoGetBoundingBoxAction\fP *action)\fC [virtual]\fP

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

void SoResetTransform::getMatrix (\fBSoGetMatrixAction\fP *action)\fC [virtual]\fP

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

void SoResetTransform::pick (\fBSoPickAction\fP *action)\fC [virtual]\fP

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

void SoResetTransform::getPrimitiveCount (\fBSoGetPrimitiveCountAction\fP *action)\fC [virtual]\fP

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

\fBSoSFBitMask\fP SoResetTransform::whatToReset

What this node instance should reset in the state when met during traversal. Default value is SoResetTransform::TRANSFORM.
