Hi Glenn and Robert, I added a call setting up the projection matrix to the FAQ for embedding a viewer in a .NET control. I was having an issue that the perspective on my camera was squished when I started with a tall and skilly control. Setting the initial projection matrix with the following line of code caused everything to work correctly.
viewer->getCamera()->setProjectionMatrixAsPerspective(30.0f, static_cast<double>(traits->width)/static_cast<double>(traits->height), 1.0f, 10000.0f); Thanks!
