Hi everyone,
I am a newbie in OSG.
- My first question is about shader.
I have added a vertex shader to a node but the node itself appears dark,
anyone has an idea?
I tried to correct the issue using a tip from the FAQ (Q32) :
stateSet->setMode( GL_RESCALE_NORMAL, osg::StateAttribute::ON );
but still no result! Anyone knows why?
- For the second question, my scene consists of 2 objects, say A and B. They
update their positions using a callback and a user data. A and B have the same
parent. Is there a mechanism to request the position of the other object in the
callback of the other object? For instance within the callback of A, I would
like to request the position of the node B.
Thanks in advance for your reponse.
Kind regards,
Franclin
