[osg-users] [forum] Using OSG after a very long hiatus

Hi Rodrigo,

The book is extremely well structured to teach you the basics and is 
also available as an eBook bringing tons of code for playing around and 
learning.

Also there are resources like:

https://github.com/xarray/osgRecipes

An up to date online tutorial needs someone to keep it up to date. Right 
now there are a ton of examples that come with OSG. I admit it takes 
time to dig through the huge stack, but in the end the cover beginners 
to advanced topics. And as they are part of the distribution they are up 
to date automatically.

IIRC openscenegraph.org is the old site. Use openscenegraph.com

The only solution for me was to start a new project. But the first time the Release didn't run, now the Debug don't run).

It is impossible to say what is wrong on your end, as you didn't even 
mention the platform, version etc. I've been using OSG for at least 5 
years now and quite frankly found it easy to learn and understand by 
looking at the examples and asking questions on the mailing list. So 
maybe check if the examples run fine (In case you're building them 
yourself: be sure to have the option set in the CMake configuration)

Cheers
Sebastian
