//! Pictures of a [`Scene`] drawn offscreen with the viewport's pipelines ([`crate::view`]): the
|
||||
//! same shading, edges, silhouettes, section cap and surface analysis the viewport shows, read
|
||||
//! back as RGBA. `solidcraft-cli snapshot`, MCP screenshots, `ui.render` and thumbnails draw
|
||||
//! through it, on the application's device ([`Capturer::new`]) or on a headless one
|
||||
//! ([`Capturer::headless`], [`shared`]). Without a qualifying adapter, the `auto` policy falls
|
||||
//! to the last tier, the CPU rasterizer ([`headless_rgba`]), and says so: every picture names the
|
||||
//! renderer that drew it (`gpu`, `gpu-software` or `cpu`); `hardware` and `software` fail with an
|
||||
//! error that names the policy.
