Detailed Description

The SoTransform class is the "all-purpose" transformation node type.

Like SoMatrixTransform, nodes of this type give the application programmer maximum flexibility when specifying geometry transformations in a scene graph. If you want to set and keep the various components of the transformation matrix in separate entities, this node type is preferable, though.

The order of operations is: first scaling is done, then rotation, then translation.

FILE FORMAT/DEFAULTS:

Transform {
    translation 0 0 0
    rotation 0 0 1  0
    scaleFactor 1 1 1
    scaleOrientation 0 0 1  0
    center 0 0 0
}

Constructor & Destructor Documentation

◆ SoTransform()

SoTransform::SoTransform ( void )

Constructor.

◆ ~SoTransform()

SoTransform::~SoTransform ( )

protectedvirtual

Destructor.

Member Function Documentation

◆ callback()

void SoTransform::callback ( SoCallbackAction * action )

virtual

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.

Reimplemented in SoTransformManip.

◆ combineLeft()

void SoTransform::combineLeft ( SoTransformation * nodeonright )

Premultiplies this transformation by the transformation in nodeonright.

◆ combineRight()

void SoTransform::combineRight ( SoTransformation * nodeonleft )

Postmultiplies this transformation by the transformation in nodeonleft.

◆ doAction()

void SoTransform::doAction ( SoAction * action )

virtual

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

Reimplemented from SoNode.

Reimplemented in SoTransformManip.

◆ getBoundingBox()

void SoTransform::getBoundingBox ( SoGetBoundingBoxAction * action )

virtual

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 calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoNode.

Reimplemented in SoTransformManip.

◆ getClassTypeId()

SoType SoTransform::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

◆ getFieldData()

const SoFieldData * SoTransform::getFieldData ( void ) const

protectedvirtual

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

Reimplemented from SoTransformation.

Reimplemented in SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip, SoTrackballManip, SoTransformBoxManip, SoTransformerManip, and SoTransformManip.

◆ getFieldDataPtr()

const SoFieldData ** SoTransform::getFieldDataPtr ( void )

staticprotected

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

Returns the SoFieldData class which holds information about fields in this node.

◆ getMatrix()

void SoTransform::getMatrix ( SoGetMatrixAction * action )

virtual

Action method for SoGetMatrixAction.

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

Reimplemented from SoNode.

Reimplemented in SoTransformManip.

◆ getPrimitiveCount()

void SoTransform::getPrimitiveCount ( SoGetPrimitiveCountAction * action )

virtual

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 calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoNode.

◆ getRotationSpaceMatrix()

void SoTransform::getRotationSpaceMatrix	(	SbMatrix &	mat,
		SbMatrix &	inv ) const

Calculates the matrices to/from rotation space.

◆ getScaleSpaceMatrix()

void SoTransform::getScaleSpaceMatrix	(	SbMatrix &	mat,
		SbMatrix &	inv ) const

Calculates the matrices to/from scale space.

◆ getTranslationSpaceMatrix()

void SoTransform::getTranslationSpaceMatrix	(	SbMatrix &	mat,
		SbMatrix &	inv ) const

Calculates the matrices to/from translation space.

◆ getTypeId()

SoType SoTransform::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoTransformation.

Reimplemented in SoCenterballManip, SoHandleBoxManip, SoJackManip, SoTabBoxManip, SoTrackballManip, SoTransformBoxManip, SoTransformerManip, and SoTransformManip.

◆ GLRender()

void SoTransform::GLRender ( SoGLRenderAction * action )

virtual

Action method for the SoGLRenderAction.

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

Reimplemented from SoNode.

Reimplemented in SoTransformManip.

◆ multLeft()

void SoTransform::multLeft ( const SbMatrix & mat )

Premultiplies this transformation by mat.

◆ multRight()

void SoTransform::multRight ( const SbMatrix & mat )

Postmultiplies this transformation by mat.

◆ pick()

void SoTransform::pick ( SoPickAction * action )

virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

Reimplemented in SoTransformManip.

◆ pointAt()

void SoTransform::pointAt	(	const SbVec3f &	frompoint,
		const SbVec3f &	topoint )

Sets the transformation to translate to frompoint, with a rotation so that the (0,0,-1) vector is rotated into the vector from frompoint to topoint.

◆ recenter()

void SoTransform::recenter ( const SbVec3f & newcenter )

Sets the center field to newcenter. This might affect one or more of the other fields.

◆ setMatrix()

void SoTransform::setMatrix ( const SbMatrix & mat )

Sets the fields to create a transformation equal to mat.

Member Data Documentation

◆ center

SoSFVec3f SoTransform::center

The center point for the rotation.

◆ rotation

SoSFRotation SoTransform::rotation

The rotation part of the transformation.

Note that there is one very common mistake that is easy to make when setting the value of a an SoSFRotation field, and that is to inadvertently use the wrong SbRotation constructor. This example should clarify the problem:

mytransformnode->rotation.setValue(0, 0, 1, 1.5707963f);

The programmer clearly tries to set a PI/2 rotation around the Z-axis, but this will fail, as the SbRotation constructor invoked above is the one that takes as arguments the 4 floats of a quaternion. What the programmer almost certainly wanted to do was to use the SbRotation constructor that takes a rotation vector and a rotation angle, which is invoked like this:

mytransformnode->rotation.setValue(SbVec3f(0, 0, 1), 1.5707963f);

SbVec3f

The SbVec3f class is a 3 dimensional vector with floating point coordinates.

Definition SbVec3f.h:51

◆ scaleFactor

SoSFVec3f SoTransform::scaleFactor

The scaling part of the transformation.

◆ scaleOrientation

SoSFRotation SoTransform::scaleOrientation

The orientation the object is set to before scaling.

◆ translation

SoSFVec3f SoTransform::translation

The translation part of the transformation.
