Surely these are FAQs?

Hi all -- It seems like there has been a rash of "help me debug my
code"-type questions lately, so I thought I'd post a short list of
debugging
techniques and other aids to help people out. I hope people find this
information to be useful.
1) You are a software engineer and you have the OSG source code. Use
it.
Step through it in a debugger. (Many of the posts I've seen lately
indicate
that the poster has not looked inside the OSG code at all. This is a
great,
free resource; learn to use it. The code doesn't lie.)
2) For simple rendering problems, use a tool like GLIntercept to
capture the
OpenGL calls. If you know OpenGL, this is a great way to track down
why
things don't render correctly. If you don't know OpenGL, buy the red
book
and learn it, otherwise you'll never be effective at coding OSG.
3) Here are a few ways to learn some basic OSG concepts that get
covered in
this email list very frequently:
a) Buy/download the Quick Start Guide
http://www.lulu.com/content/paperback-book/openscenegraph-quick-start-guide/
767629
There is a color version, b&w (which is cheaper), PDF (which is
free),
and a Chinese version.
B) Search the mail list archives:
http://groups.google.com/group/osg-users?hl=en
If you're a beginner, your question has probably been discussed
and
answered multiple times.
C) Get familiar with the OSG wiki:
http://www.openscenegraph.org
4) If you really need professional help, consider purchasing a support
contract from myself or Robert Osfield, or contracting with someone
else on
the list for support. You are more likely to get quality help if you
pay for
it.
