2//! `viewport-lib` — a 3D viewport library for `wgpu` applications.
3//!
4//! Built on `wgpu` and `glam`, with no required UI toolkit. The crate provides
5//! the renderer, camera, picking, and interaction pieces; host applications keep
6//! control of their own windowing and event loop.
7//!
8//! # Quick start
9//!
10//! 1. Create a [`ViewportRenderer`] from a `wgpu::Device` and target format.
11//! 2. Upload meshes or volumes through [`ViewportGpuResources`].
12//! 3. Build a [`FrameData`] each frame (camera via [`CameraFrame`] and
13//!    [`RenderCamera`], scene content via [`SceneFrame`], viewport chrome via
14//!    [`ViewportFrame`], etc.).
15//! 4. Call [`ViewportRenderer::prepare`] and then [`ViewportRenderer::paint_to`].

17/// Error types for the viewport library.
18pub mod error;
19
20/// Arcball camera, frustum, view presets, and animator.
21pub mod camera;
22/// BVH picking, marching cubes, isolines, and cap geometry.
23pub mod geometry;
24/// Gizmo, snap, selection, annotation, picking, and input.
25pub mod interaction;
26/// Main viewport renderer wrapping all GPU resources.
27pub mod renderer;
28/// GPU resource container (pipelines, buffers, bind groups).
29pub mod resources;
30/// Scene graph, material, traits, and AABB.
31pub mod scene;
32/// Axes orientation indicator.
