Currently the View Window receives key events, even if it's not selected. This means if e.g. I'm typing something in the console, it may still move the camera. Looking around with the arrow keys is also awkward. Ideally, we should have mouselook. The problem is, if we do mouse look while the view window has focus, it will make it awkward for users when they try to use the tools. A possible solution is to enable mouselook when a specific key is held down (e.g. in Blender, this is middle mouse button).

Currently, the X3D View Window forces X3D to re-render the scene every frame. Because this is software rendering and X3D is currently built in debug mode, this is having a huge negative impact on performance. Also, once X3D is done rendering the scene, it has to be uploaded as an OpenGL texture which is also expensive. To fix this, we should:

• Make it so the scene is only re-rendered when necessary
• Make the editing tools more aware of the View Window. If something in the tool changes, then the View Window should automatically be redraw. A potential issue is that a tool may draw an overlay on the level e.g. the extrude tool shows a preview. A solution may be to give each tool a custom View Window rendering callback that gets called for the current tool when the View Window needs to be redrawn.
• When the camera moves, the View Window should also be redrawn
