Struct PackedGeometry 

pub struct PackedGeometry { /* private fields */ }

Materialized primitive geometry with contiguous attribute and index buffers.

use draco_gltf::{ComponentType, PackedAttribute, PackedGeometry, PrimitiveMode};

let position = PackedAttribute::new(
    "POSITION", 1, 3, ComponentType::F32, false, vec![0; 12],
)?;
let geometry = PackedGeometry::new(PrimitiveMode::Points, vec![position], None)?;
assert_eq!(geometry.vertex_count(), 1);

Implementations

impl PackedGeometry

pub fn new( mode: PrimitiveMode, attributes: Vec<PackedAttribute>, indices: Option<PackedIndices>, ) -> Result<Self, GeometryError>

Creates and validates one materialized primitive.

pub const fn mode(&self) -> PrimitiveMode

Returns the primitive topology.

pub fn vertex_count(&self) -> usize

Returns the shared vertex count.

pub fn attributes(&self) -> &[PackedAttribute]

Borrows the packed vertex attributes in document order.

pub fn indices(&self) -> Option<&PackedIndices>

Borrows the optional packed index stream.

pub fn validate(&self, profile: ValidationProfile) -> Result<(), GeometryError>

Validates the geometry against a glTF profile.
