Hi Chris,
That's great to have more papers about the implementations of more OSG
components! Thank you for the efforts on them. :-)
Is it possible to translate these papers into Chinese and put them on some
Chinese forums, of course, with original copyrights?
Thanks,

I should note that my needs are very similar to the ones described in this post:

I adapted the sample code given at the end of that thread and found that while
I was able to retrieve the correct pixel values, I also was
Hello,
I click on a point in my node.
I get a world intersection point (hitr-getWorldIntersectPoint()).
I want to center my camera on this point that is to say this point becomes the
pivot point of the rotation of the camera.
Can you help me please?
Thank you!
Cheers,

Hi Ethan,
Maybe you could just keep it all on the gpu, and create the text for the
hud in a shader like drawtext GLSL shader

Whatever you end up doing, you want to avoid doing the equivalent of
glReadPixels since that stalls the pipe and is relatively slow. I
noticed that this was one of the suggestions in the link provided

Yes, sure, that'd be fine. Just send me PDFs of the translations so I can
keep a copy on my site too.

The MxEventHandler class in the osgWorks project has an event handler that lets
you specify the center of rotation. Documentation is here:

so you can see that ctrl+shift+leftmouse sets the new center of
