Function tobj::load_obj_buf

pub fn load_obj_buf<B, ML>(reader: &mut B, material_loader: ML) -> LoadResult where
    B: BufRead,
    ML: Fn(&Path) -> MTLLoadResult, 

Load the various meshes in an OBJ buffer of some kind, e.g. a network stream, text file already in memory or so on.

You must pass a "material loader" function, which will return a material given a name. A trivial material loader may just look at the file name and then call load_mtl_buf with the in-memory MTL file source. Alternatively it could pass an MTL file in memory to load_mtl_buf to parse materials from some buffer.

Example

The test for load_obj_buf includes the OBJ and MTL files as strings and uses a Cursor to provide a BufRead interface on the buffer.

use std::io::Cursor;

const CORNELL_BOX_OBJ: &'static str = include_str!("cornell_box.obj");
const CORNELL_BOX_MTL1: &'static str = include_str!("cornell_box.mtl");
const CORNELL_BOX_MTL2: &'static str = include_str!("cornell_box2.mtl");

let m = tobj::load_obj_buf(&mut Cursor::new(CORNELL_BOX_OBJ), |p| {
    match p.to_str().unwrap() {
        "cornell_box.mtl" => tobj::load_mtl_buf(&mut Cursor::new(CORNELL_BOX_MTL1)),
        "cornell_box2.mtl" => tobj::load_mtl_buf(&mut Cursor::new(CORNELL_BOX_MTL2)),
        _ => unreachable!(),
    }
});
