< BLOCKQUOTE > Transform - is group which all children are transformed by the the Transform's osg::Matrix.
Typical uses
2001-09-20 05:19:47 +08:00
of the Transform is for positioning objects within a scene or
2001-12-30 23:12:29 +08:00
producing trackball functionality or for animation.
2002-02-09 18:54:18 +08:00
The Transform node can be customized via the ComputeTransfromCallback which can be
attached to the node, this might be used to convert internal representations of the transformation
into generic osg::Matrix'c which are used during scene grpah traversal, such as CullTraversal and IntersectionTraversal.
2001-12-30 23:12:29 +08:00
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. One can done transparently through OpenGL's
use of either GL_NORMALIZE and GL_SCALE_NORMALIZE modes. Further
background reading see the glNormalize documentation in the OpenGL Reference
Guide (the blue book). To enable it in the OSG, you simple 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 realtive to its parent reference frame,
or relative to an absolute coordinate frame. RELATIVE_TO_PARENTS is the default.
Note, setting the RefrenceFrame to be RELATIVE_TO_ABSOLUTE will also set the CullingActive flag on the
transform, and hence all its parents, to false, therby disabling culling of it and all its
parents. This is neccessary to prevent inappropriate culling, but may impact of cull times
if the absolute transform is deep in the scene graph, it is therefore recommend to only use
abolsoute Transforms at the top of the scene, for such things as headlight LightSource's or
Head up displays.
