<BLOCKQUOTE>A Transform is a group node for which all children are transformed by
|
|
a 4x4 matrix. It is often used for positioning objects within a scene,
|
|
producing trackball functionality or for animation.
|
|
|
|
<P>Transform itself does not provide set/get functions, only the interface
|
|
for defining what the 4x4 transformation is. Subclasses, such as
|
|
MatrixTransform and PositionAttitudeTransform support the use of an
|
|
osg::Matrix or a osg::Vec3/osg::Quat resprectively.
|
|
The Transform node can be customized via the ComputeTransfromCallback
|
|
which can be attached to the node. This might be used to convert from
|
|
internal representations of the transformation into generic osg::Matrix
|
|
objects which are used during scene grpah traversal, such as
|
|
CullTraversal and IntersectionTraversal.
|
|
|
|
<P>Note: if the transformation matrix scales the subgraph then the normals
|
|
of the underlying geometry will need to be renormalized to be unit
|
|
vectors once more. This can be done transparently through OpenGL's
|
|
use of either GL_NORMALIZE and GL_SCALE_NORMALIZE modes. For further
|
|
background reading see the glNormalize documentation in the OpenGL
|
|
Reference Guide (the blue book). To enable it in the OSG, you simply
|
|
need to attach a local osg::StateSet to the osg::Transform, and set
|
|
the appropriate mode to ON via
|
|
stateset->setMode(GL_NORMALIZE, osg::StateAttribute::ON);</BLOCKQUOTE>

<DD>Set the transform's ReferenceFrame, either to be relative to its
|
|
parent reference frame, or relative to an absolute coordinate
|
|
frame. RELATIVE_TO_PARENTS is the default.
|
|
Note: setting the ReferenceFrame to be RELATIVE_TO_ABSOLUTE will
|
|
also set the CullingActive flag on the transform, and hence all
|
|
of its parents, to false, thereby disabling culling of it and
|
|
all its parents. This is neccessary to prevent inappropriate
|
|
culling, but may impact cull times if the absolute transform is
|
|
deep in the scene graph. It is therefore recommend to only use
|
|
absolute Transforms at the top of the scene, for such things as
|
|
heads up displays.
