# Cameras — user documentation

The **viewpoint side**: the active camera, the orbital controller, unified input, and the
GPU-driven pipeline (frustum culling, LOD) that the camera drives.

| Page | Topic |
|------|-------|
| [Camera & input](camera-input.md) | Active camera, `CameraController` (orbit/zoom/reset), unified keyboard/mouse state, recipes |
| [GPU-driven rendering](gpu-driven.md) | GPU world matrices + indirect draws, opt-in frustum culling, LOD, debugging |

Example folder: [`lib/examples/cameras/`](../../../lib/examples/cameras/README.md)
(`culling`).
