Struct RenderScene 

pub struct RenderScene { /* private fields */ }

The scene: insertion-ordered solids + an exact name index (R8 — the getObjectByName heuristic-scoring lookup is replaced by this map).

Implementations

impl RenderScene

pub fn new() -> Self

pub fn insert_solid(&mut self, solid: SolidDisplay)

Insert or replace a solid by name (replacement keeps insertion order — a boolean result reusing its target’s name stays in place).

pub fn clear(&mut self)

Drop every solid (the scene rebuild path clears then repopulates).

pub fn drain(&mut self) -> Vec<SolidDisplay>

Empty the scene, RETURNING every solid by value (the name index is cleared and the vec is mem::take-n out). The history-apply seam MOVES existing displays out this way to reinsert the reused ones without cloning their meshes — a scene-free crate::pipeline::SceneRunner delta is applied by draining then reinserting in snapshot order.

pub fn set_color_override( &mut self, name: &str, color: Option<[f32; 3]>, ) -> bool

Set (or clear) a solid’s metadata color override, bumping its revision so the renderer re-derives the base style. Returns false if unknown.

pub fn set_visible(&mut self, name: &str, visible: bool) -> bool

Set a solid’s visibility (R11). Returns false if unknown.

pub fn listing_json(&self) -> String

Scene enumeration for the host scene-tree panel (R11): names, kind, visibility, child face/edge/vertex counts — as JSON.

pub fn remove_solid(&mut self, name: &str) -> bool

Remove a solid by exact name.

pub fn solid(&self, name: &str) -> Option<&SolidDisplay>

pub fn solid_mut(&mut self, name: &str) -> Option<&mut SolidDisplay>

pub fn solids(&self) -> &[SolidDisplay]

Insertion-ordered iteration (deterministic — drives draw order).

pub fn edge_polyline_world(&self, name: &str) -> Option<Vec<[f64; 3]>>

The world-space polyline of the first display edge named name across all solids (widened to f64), or None when no edge carries that exact name. The engine-native sketch pickEdges tool (S6b-2) uses this to fetch a picked scene edge’s geometry for projection into the sketch plane. There is no name index for edges (only solids), so this is a linear scan — fine for the interactive per-click use.

pub fn edge_solid_name(&self, name: &str) -> Option<&str>

The name of the solid owning the first display edge named name, or None (the companion of edge_polyline_world — the pickEdges tool stores it as external-ref metadata).

pub fn is_empty(&self) -> bool

pub fn bbox(&self) -> Aabb

World bbox over every VISIBLE solid.

impl RenderScene

pub fn set_entity_visible( &mut self, solid: &str, kind: EntityKind, index: usize, visible: bool, ) -> bool

Show/hide ONE face/edge/vertex of a solid. False if the solid is unknown.

pub fn set_group_visible( &mut self, solid: &str, kind: EntityKind, visible: bool, ) -> bool

Show/hide a whole group (all faces / all edges / all vertices) of a solid. False if the solid is unknown.

pub fn entity_visible( &self, solid: &str, kind: EntityKind, index: usize, ) -> Option<bool>

Whether entity index of kind on solid is shown (None if unknown).

pub fn group_visibility( &self, solid: &str, kind: EntityKind, ) -> Option<GroupState>

The group tristate for solid’s kind (None if the solid is unknown).

Trait Implementations

impl Debug for RenderScene

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RenderScene

fn default() -> RenderScene

Returns the “default value” for a type.
