SoComposeMatrix: The socomposematrix class is used to compose a matrix from miscellaneous transformations.

SYNOPSIS

Inherits SoEngine.

Public Member Functions

Member Function Documentation

\fBSoType\fP SoComposeMatrix::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.

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

Implements SoBase.

const \fBSoFieldData\fP * SoComposeMatrix::getFieldData (void) const\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 SoFieldContainer.

const \fBSoEngineOutputData\fP * SoComposeMatrix::getOutputData (void) const\fC [virtual]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

Member Data Documentation

\fBSoMFVec3f\fP SoComposeMatrix::translation

Input field with set of translation vectors for the output matrices.

\fBSoMFRotation\fP SoComposeMatrix::rotation

Input field with set of rotations for the output matrices.

\fBSoMFVec3f\fP SoComposeMatrix::scaleFactor

Input field with set of scale vectors for the output matrices.

\fBSoMFRotation\fP SoComposeMatrix::scaleOrientation
