# Objective
Implements cascaded shadow maps for directional lights, which produces better quality shadows without needing excessively large shadow maps.
Fixes#3629
Before
After
## Solution
Rather than rendering a single shadow map for directional light, the view frustum is divided into a series of cascades, each of which gets its own shadow map. The correct cascade is then sampled for shadow determination.
---
## Changelog
Directional lights now use cascaded shadow maps for improved shadow quality.
## Migration Guide
You no longer have to manually specify a `shadow_projection` for a directional light, and these settings should be removed. If customization of how cascaded shadow maps work is desired, modify the `CascadeShadowConfig` component instead.
# Objective
This PR reorganizes majority of the scene viewer example into a module of plugins which then allows reuse of functionality among new or existing examples. In addition, this enables the scene viewer to be more succinct and showcase the distinct cases of camera control and scene control.
This work is to support future work in organization and future examples. A more complicated 3D scene example has been requested by the community (#6551) which requests functionality currently included in scene_viewer, but previously inaccessible. The future example can now just utilize the two plugins created here. The existing example [animated_fox example] can utilize the scene creation and animation control functionality of `SceneViewerPlugin`.
## Solution
- Created a `scene_viewer` module inside the `tools` example folder.
- Created two plugins: `SceneViewerPlugin` (gltf scene loading, animation control, camera tracking control, light control) and `CameraControllerPlugin` (controllable camera).
- Original `scene_viewer.rs` moved to `scene_viewer/main.rs` and now utilizes the two plugins.
