Struct SceneNode 

pub struct SceneNode {
    pub light: Option<LightSource>,
    /* private fields */
}

A node in the scene graph.

Fields

light: Option<LightSource>

Light source carried by this node. Position and direction are resolved from world_transform at collect time; the values stored here serve as the local-space template.

Implementations

impl SceneNode

pub fn id(&self) -> NodeId

Unique identifier for this node.

pub fn name(&self) -> &str

Display name of this node.

pub fn mesh_id(&self) -> Option<MeshId>

GPU mesh associated with this node, or None if no mesh has been uploaded.

pub fn lod_group(&self) -> Option<LodGroupId>

LOD group this node draws through, or None for a plain mesh.

pub fn material(&self) -> &Material

Material parameters (colour, shading, texture) for this node.

pub fn appearance(&self) -> &ItemSettings

Per-node appearance overrides (hidden, unlit, opacity, wireframe).

pub fn is_visible(&self) -> bool

Whether this node is visible.

pub fn show_normals(&self) -> bool

Whether per-vertex normals are rendered for this node.

pub fn local_transform(&self) -> Mat4

Local transform relative to this node’s parent (or world if no parent).

pub fn world_transform(&self) -> Mat4

World-space transform. Updated by Scene::update_transforms().

pub fn parent(&self) -> Option<NodeId>

Parent node ID, or None if this is a root node.

pub fn children(&self) -> &[NodeId]

IDs of this node’s direct children.

pub fn layer(&self) -> LayerId

Layer this node belongs to.

pub fn receives_decals(&self) -> bool

Whether projected decals land on this surface.

pub fn set_receives_decals(&mut self, v: bool)

Set whether projected decals land on this surface.

Trait Implementations

impl ViewportObject for SceneNode

fn id(&self) -> u64

Unique object identifier.

fn mesh_id(&self) -> Option<u64>

GPU mesh key (index into mesh storage). None if no mesh uploaded yet.

fn model_matrix(&self) -> Mat4

World-space model matrix (Translation * Rotation * Scale).

fn position(&self) -> Vec3

World-space position.

fn rotation(&self) -> Quat

Orientation as a quaternion.

fn scale(&self) -> Vec3

Per-axis scale factors. Defaults to (1, 1, 1) if not overridden.

fn is_visible(&self) -> bool

Whether this object should be rendered.

fn colour(&self) -> Vec3

RGB colour in linear 0..1 range.

fn show_normals(&self) -> bool

Whether to render per-vertex normal visualization.

fn material(&self) -> Material

Material for this object. Default derives from colour().

fn render_mode(&self) -> RenderMode

Render mode override.

fn transparency(&self) -> f32

Alpha transparency (1.0 = fully opaque).
