Custom view with path tracing

Turn the device and move the camera freely, and the final image is path traced in your browser. No upload and no render queue.
The custom view uses the same models as the ready-made perspectives. Orbit around the device or fly through the scene, and set the focal length and the aperture. While you hold still, the path tracer adds samples until the image is clean.
Export renders at the size you choose, in several quality levels.
Fixes and improvements
- Preview quality at full, half or a quarter of the resolution, for slower graphics cards
- The light follows the camera, as in the ready-made views
