How to: draw scene with camera background in a FBView

This is the forum question from Autodesk Area, so I will add it to the tips for OpenReality SDK:

You can operate with camera background by using property BackGroundColor.

So to get color at current frame:

FBColor color = lCamera.BackGroundColor;
Now we have to set clear color using OpenGL command:

glClearColor( color[0], color[1], color[2], color[3] );
