Implementations

impl Geometry

pub fn uuid(&self) -> Uuid

Returns the unique identifier for this geometry.

pub fn morph_target_count(&self) -> u32

Returns the number of morph targets in this geometry.

pub fn morph_vertex_count(&self) -> u32

Returns the vertex count per morph target.

pub fn morph_target_names(&self) -> &[String]

pub fn new() -> Geometry

pub fn layout_version(&self) -> u64

pub fn structure_version(&self) -> u64

pub fn data_version(&self) -> u64

pub fn attributes(&self) -> &HashMap<String, Attribute, FxBuildHasher>

pub fn index_attribute(&self) -> Option<&IndexAttribute>

pub fn index_attribute_mut(&mut self) -> &mut Option<IndexAttribute>

pub fn set_attribute(&mut self, name: &str, attr: Attribute)

pub fn remove_attribute(&mut self, name: &str) -> Option<Attribute>

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

pub fn get_attribute_mut(&mut self, name: &str) -> Option<&mut Attribute>

pub fn add_morph_attribute(&mut self, morph_name: &str, attr: Attribute)

pub fn build_morph_storage_buffers(&mut self)

Builds compact Storage Buffers from morph_attributes Layout: [ Target 0 all vertices | Target 1 all vertices | … ] Each vertex stores 3 f32 values (compact Vec3)

pub fn morph_position_bytes(&self) -> Option<&[u8]>

Gets the byte slice of morph position data

pub fn morph_normal_bytes(&self) -> Option<&[u8]>

Gets the byte slice of morph normal data

pub fn morph_tangent_bytes(&self) -> Option<&[u8]>

Gets the byte slice of morph tangent data

pub fn has_morph_targets(&self) -> bool

Checks if morph targets exist

pub fn set_indices(&mut self, indices: &[u16])

pub fn set_indices_u32(&mut self, indices: &[u32])

pub fn compute_vertex_normals(&mut self)

pub fn compute_bounding_volume(&mut self)

pub fn set_bounding_volume(&mut self, bbox: BoundingBox)

Sets the bounding volume directly from pre-computed AABB bounds.

Used by the quantised geometry pipeline where the position data is not in Float32x3 format. The glTF specification guarantees that accessor min/max are always real-valued floating-point world-space coordinates, so we can use them directly without decoding the quantised vertex data on the CPU.

pub fn set_interleaved_attributes( &mut self, interleaved_data: Vec<u8>, stride: u64, attributes: Vec<(&str, VertexFormat, u64)>, )

Sets interleaved attributes Creates multiple Attributes sharing the same Buffer from an interleaved array

pub fn update_attribute_region<T>( &mut self, name: &str, offset_bytes: u64, data: &[T], )

where T: Pod,

Partially updates attribute data

pub fn shader_defines(&self) -> &ShaderDefines

Computes the geometry’s shader macro definitions

Uses internal caching mechanism, only recalculates when layout_version changes. This avoids Map traversal overhead on the hot path.

pub fn new_box(width: f32, height: f32, depth: f32) -> Geometry

pub fn new_sphere(radius: f32) -> Geometry

pub fn new_plane(width: f32, height: f32) -> Geometry
