Object names can be double-clicked in the tree view panel for quick camera
navigation. All side panels and toolbars are dockable widgets that can be popped out
and reorganized as needed. Panels can also be stacked to create a docked widget with
tabs. The central widget that provides the camera view into the scene cannot be
detached from the main window in this way. See the `View` menu to enable debug
console widgets for open scenes or reopen previously closed panels.
The small triangles floating near 3D models represent the light source being used for the shader.

### Controls
You can fly around the scene if you hold the right mouse button and use WASD.
If you see a small triangle floating by a model it represents the light source
that is being used for the shader rendering the model. These appear on models
