Hi Sumit,
mayb you have to update the light direction vector instead of the light
position? I think the LISP shadow ignores light position and only uses light
direction.

Hi scat,
if you need to use OSG with Qt I suggest to try a more recent OSG version. If
you download OSG 2.9.14 you can find the osgQt lib and a osgviewerQtContext

Looking at the source code for computeLocalToWorldMatrix and
computeWorldToLocalMatrix, the node visitor argument is ignored, so it would
seem safe to use these functions and pass NULL as the second argument. I

It is not clear from your request what you want. If you wanted it all

It looks like a problem with OSG to me. OSG should be using
glVertexAttribIPointer instead of glVertexAttribPointer when dealing with
integer attributes.
