A scene's `on_top` lines are drawn after every depth-tested layer, over the model, so a concentrated load at a point inside the part can be seen from any side (#78). `render_layers` takes a list of overlays (the setup's symbols and the selection highlight become separate layers), and draws every layer's labels. `Camera::length_per_pixel` is the model length a pixel spans at the target: the scale symbols of a fixed screen size are drawn at.

//! The FieldCraft egui front end.
|
||
//!
|
||
//! A thin shell over [`fieldcraft_engine::Session`]: panels read engine state and act through
|
||
//! commands ([`ModelApp::run`]); nothing here owns model data. The window follows the Craft
|
||
//! family's layout (SolidCraft, VectorCraft):
|
||
//!
|
||
//! - the title bar ([`appbar`]): the app, quick actions (File menu, save, undo, redo, Solve,
|
||
//! search, theme, help) and the model's document tab;
|
||
//! - the ribbon ([`toolbar`]): the workspace switcher, its tabs, and panels of icon buttons whose
|
||
//! labelled drop-downs list the whole catalogue (coming-soon entries greyed with their
|
||
//! milestone);
|
||
//! - the browser on the left ([`browser`]): the model's geometry, mesh and definitions;
|
||
//! - the viewport ([`viewport`]) with its navigation bar, orientation gizmo and selection bar
|
||
//! (picking faces, edges, vertices, bodies, nodes and elements: [`selection`]);
|
||
//! - the context panel on the right ([`context`]), only while there is context: the open command
|
||
//! form, the results controls, the selected definition's properties;
|
||
//! - the command line and status ([`palette`]), and the journal timeline at the bottom
|
||
//! ([`timeline`]). Every command is also one search away (S or Cmd/Ctrl+K).
|
||
//!
|
||
//! The control channel's requests are handled here ([`control`]); the desktop app owns the
|
||
//! socket. Structure and conventions follow SolidCraft's `crates/ui-egui` (MIT OR Apache-2.0),
|
||
//! see ATTRIBUTION.md.
