[osg-users] Using OsgViewerMFC to load a sphere

Hi All,

 

I am a beginner of OSG. 

I used OsgViewerMFC to load a sphere into the scene, but it displays as an
ellipsoid.

The radius doesn't seem to be equal in two orthotropic axes.

 

I find that it may be related to the width and height of the view window
when initializing.

 

The following codes are from OsgViewerMFC:

 

::GetWindowRect(m_hWnd, &rect);

.

traits->x = 0;

traits->y = 0;

traits->width = rect.right - rect.left;

traits->height = rect.bottom - rect.top;

.

osg::GraphicsContext* gc =
osg::GraphicsContext::createGraphicsContext(traits.get());

 

How to solve this?

Thanks for your advices in advance.

Tang
