Trait dae_parser::geom::VertexLoad

pub trait VertexLoad<'a, C: ?Sized = ()>: Clone {
    fn position(ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32) -> Self;
    fn add_normal(
        &mut self, 
        ctx: &C, 
        reader: &SourceReader<'a, XYZ>, 
        index: u32
    );
    fn add_texcoord(
        &mut self, 
        ctx: &C, 
        reader: &SourceReader<'a, ST>, 
        index: u32, 
        set: Option<u32>
    );
}

A trait, to be implemented by user types, to describe how to construct a vertex object from the stored data. The context C is an arbitrary type that can be used for getting (or modifying, with interior mutability) additional data to create the object.

Required methods

fn position(ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32) -> Self

Construct a new vertex using only position data.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 3] as the position.

fn add_normal(&mut self, ctx: &C, reader: &SourceReader<'a, XYZ>, index: u32)

Add normal data to a vertex.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 3] as the normal.

fn add_texcoord(
    &mut self,
    ctx: &C,
    reader: &SourceReader<'a, ST>,
    index: u32,
    set: Option<u32>
)

Add texture coordinate data to a vertex.

The position index is provided as is, but the intended use is to call reader.get(i) and use the resulting [f32; 2] as the u-v data.
