Hi All, How can I draw a Transparent sphere? I need to draw a sphere inside a Transparent one. Can anyone tell me how to set the material and color of the Transparent one. Thanks, Ahmed Nawar <>___ osg-users mailing list osg-users@lists.openscenegr

Well, let's say that i'm adding like 50 cameras so basically 50 fbos ...

Hi, Some hints: 1. Be sure that test->size() is equal to numVertex 2. I don't know what the "at" method is, I couldn't find it either on the TemplateArray class or the std::vector class. Try with the vector [] operator, ie: (*test)[i] = trans 3. If you are updating the vertex data once per fram

How many fbos is "a lot"? Hundreds of BindBuffer calls per frame can not be a good thing, perhaps that explains the performance hit. -Paul > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf > Of [EMAIL PROTECTED] > Sent: Wednesday, February 06, 2008

Thanks to all who replied. I've now written a cleaner fix. The focus on modifiers was silly.

Your question has unstated context and assumptions. Without more specifics, there are many interpretations: - OSG does not have to be "installed" on a computer to work, in that you do not need to run an "installer". There is a .zip of prebuilt OSG 2.2.0 at http://mew.cx/osg/ that can be unpacked
