Fields

name: Option<String>

The text string name of this element.

material: Option<String>

Declares a symbol for a material. This symbol is bound to a material at the time of instantiation; see Instance<Geometry> and BindMaterial. If not specified then the lighting and shading results are application defined.

count: usize

The number of line/triangle/polygon primitives.

inputs: InputList

The vertex attribute access information.

data: T

The specific data for the geometry element.

extra: Vec<Extra>

Provides arbitrary additional information about this element.

Implementations

impl<T> Geom<T>

pub fn importer<'a, R: UrlResolver<'a, Source>>( &'a self, res: &R, vimp: VertexImporter<'a>, ) -> Result<Importer<'a>, R::Error>

Construct an Importer from a VertexImporter and a UrlResolver.

impl Geom<LineGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, count: usize, prim: Box<[u32]>, ) -> Self

Construct a new Lines object from a data buffer. The data buffer prim contains exactly count lines, consisting of 2 vertices, each consisting of inputs.len() indices, for a total of inputs.len() * 2 * count values.

impl Geom<LineStripGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, prim: Vec<Box<[u32]>>, ) -> Self

Construct a new LineStrips object from a data buffer. Each buffer in data contains 2 or more vertices, each consisting of inputs.len() indices, for a total of inputs.len() * verts values.

impl Geom<PolygonGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, prim: Vec<PolygonHole>, ) -> Self

Construct a new Polygons object from raw data.

impl Geom<PolyListGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, vcount: Box<[u32]>, prim: Box<[u32]>, ) -> Self

Construct a new PolyList object from a data buffer. Each value n in vcount corresponds to a polygon with n vertices, to which inputs.len() * n index values are associated in prim.

impl Geom<TriangleGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, count: usize, prim: Box<[u32]>, ) -> Self

Construct a new Triangles object from a data buffer. The data buffer prim contains exactly count triangles, consisting of 3 vertices, each consisting of inputs.len() indices, for a total of inputs.len() * 3 * count values.

impl Geom<TriFanGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, prim: Vec<Box<[u32]>>, ) -> Self

Construct a new TriFans object from a data buffer. Each buffer in data contains 3 or more vertices, each consisting of inputs.len() indices, for a total of inputs.len() * verts values.

impl Geom<TriStripGeom>

pub fn new( material: Option<String>, inputs: Vec<InputS>, prim: Vec<Box<[u32]>>, ) -> Self

Construct a new TriStrips object from a data buffer. Each buffer in data contains 3 or more vertices, each consisting of inputs.len() indices, for a total of inputs.len() * verts values.
