< BLOCKQUOTE > Transform - is group which all children
are transformed by the the Transform's osg::Matrix. Typical uses
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.
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 Type, which can be DYNAMIC - the Matrix
value is updated during the main loop, or STATIC - the Matrix
is constant throughout the life of the main loop. STATIC
2001-12-25 05:56:22 +08:00
Transforms can be optimized away is some instances, which
2001-12-30 23:12:29 +08:00
can improve performance so unless you plan to modify the
Matrix explicitly set the Matrix to STATIC. The default
2001-12-25 05:56:22 +08:00
value is DYNAMIC.
