Struct Instance

pub struct Instance {
    pub path: String,
    pub node: String,
    pub geometry: GeometryRef,
    pub material: usize,
    pub world: Transform,
    pub matrix: [f32; 16],
    pub bounds: Bounds,
}

One drawn geometry of one node at one path.

Fields

path: String

Child names from the root, joined by /, for example site/Storey/Wall. Resolve it with [Composition::get] to show the node’s attributes on pick. Unique per node, shared by the instances of one node with several kinds of geometry.

node: String

The path of the node that defined this node, [ComposedNode::path].

geometry: GeometryRef

The shared geometry drawn.

material: usize

Index into RenderScene::materials.

world: Transform

The node’s world transform in the file’s coordinates.

matrix: [f32; 16]

Column-major f32 matrix from buffer coordinates to world coordinates minus the scene origin, the layout of glTF node.matrix.

bounds: Bounds

World bounds of the drawn vertices, in the file’s coordinates.

Implementations

impl Instance

pub fn mirrored(&self) -> bool

Whether the world transform mirrors, so triangle winding is reversed.

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Instance

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Instance

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

Formats the value using the given formatter.

impl PartialEq for Instance

fn eq(&self, other: &Instance) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
