Struct PrimitiveRef 

pub struct PrimitiveRef<'a> { /* private fields */ }

Stable reference to a primitive in the lossless document.

Implementations

impl<'a> PrimitiveRef<'a>

pub fn mesh_index(self) -> MeshIndex

Returns the mesh containing this primitive.

pub fn primitive_index(self) -> usize

Returns the primitive’s zero-based position within its mesh.

pub fn value(self) -> &'a Value

Returns the primitive’s lossless JSON object.

pub fn attributes(self) -> Option<&'a [(String, Value)]>

Returns the primitive attribute map.

pub fn attribute_indices( self, ) -> impl Iterator<Item = (&'a str, AccessorIndex)> + 'a

Iterates over named primitive attribute accessor indexes.

pub fn indices(self) -> Option<AccessorIndex>

Returns the optional index accessor.

pub fn material(self) -> Option<MaterialIndex>

Returns the optional material index.

pub fn mode(self) -> u32

Returns the primitive mode, defaulting to TRIANGLES (4).

pub fn morph_targets(self) -> impl Iterator<Item = &'a [(String, Value)]> + 'a

Iterates over morph-target attribute maps.

pub fn extension(self, name: &str) -> Option<&'a Value>
