Re: [osg-users] Simple Loading Tutorial
Hello Sam,
When I run the code to load a simple object (that you supplied above) with a
direct path, I get no errors but osgviewer seems to load nothing, just the
default blue background with no model. Ive tried different .osg and .obj files
but no luck.
If you're on Windows, make sure you specify the full path with slashes
("/") instead of backslashes, or escape the backslashes by doubling them
("\\"). In a string, a backslash starts an escape sequence (like \n for
newline, etc.) so if you specify a path like C:\models\bob.obj the
compiler will not be able to find it because it will interpret \m and \b
as escape sequences. But using C:/models/bob.obj or C:\\models\\bob.obj
will work.
Also, make sure you have the plugin to read your model's file format.
Set the notify level higher (set OSG_NOTIFY_LEVEL=DEBUG) to see what's
going on - OSG will print out whether it can find and open the plugin to
read your model, and then whether it can read the model itself, in the
console (stdout and stderr).
Hope this helps,
J-S

Re: [osg-users] Simple Loading Tutorial
Thanks for that- I have tried to get the osg wiki FAQ/tutorials but the site has been down since Wednesday so having trouble getting to them at the moment.

Ive tried different .osg and .obj files but no luck. Thanks for your help to a newbie!

There is an OSG_FILE_PATH variable, but of course you can always just specify the full path. FYI, in addition to the Quick Start Guide, there is also a FAQ on the OSG wiki that you might want to read through. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Simple Loading Tutorial
Have you taken a look at the OSG Quick Start Guide and its examples?
http://www.skew-matrix.com/OSGQSG/index.html
Anyway, a bare-bones OSG example would be:
#include
#include
int main()
{
osgViewer viewer;
viewer.setSceneData( osgDB::ReadNodeFile( "cow.osg" ) );
viewer.run();
}

[osg-users] Simple Loading Tutorial
Hi all, I've recently been trying to get my head around OSG, been trying the inbuilt examples and am not getting very far. I thought i'd check out the OSG tutorials but the site seems to have been down for the last few days now. Is there any specific example that I should be looking at just to learn how to load a model into OSG, as some seem a little more complex than this. Hopefully that made sense, cheers ... Thank you!
