Hi Chen,
It looks like the OpenGL driver isn't working properly within the
virtualbox, you'll need to go look at virtualbox forums to see how
they resolve these issues.
Or... just dual boot.

Hi Mike,
The only problem I could spot in your code is you are using a
TextureRectangle which uses pixel coordinates rather than standard
OpenGL non dimensionsal texture coordinates, this means you have to
set the texture coordinates on your geometry in pixel coordaintes - so

HI Wilbur,
My guess it's small feature culling the small spheres when the model
extents are larger which causes the initial viewpoint to be further
away.
You can swtich off small feature culling via

~osg::CullingSet::SMALL_FEATURE_CULLING);
Hi Yong,
The simple answer is you can't convert a NULL to Vec3, it simply is
wrong and compiler is right to bark about it.
The best way to write code like is would be to do:
bool lineintersection(const osg::Vec3f p1, const osg::Vec3f p2,
const osg::Vec3f p3, const osg::Vec3f p4, osg::Vec3f

What you'll need to do is create a copy of the aircraft subgraph

This could be a driver issue, a Qt issue or something else entirely.

A Texture2DArray is something designed for shader work, the fixed

The OSG doesn't have general collision support, it only provides line

camera-setRenderingCache(0);
This has worked fine
