Rust HxA mesh parser

Description

This is a WIP parser for the mesh format specified by Eskil Steenberg.
Link to HxA GitHub

Features

• Loading HxA files into Rust structures
• Searching through HxA Rust structures to obtain data

Examples

To load a hxa file use the from() function and pass a filepath.

use hxa;
let my_hxa = hxa::HXAFile::from("Cube.hxa");

You can parse this as is, or use the find functions to quickly obtain data:

use hxa::conventions::{hard,soft};

let model_geometry = my_hxa.get_first_geometry()
    .expect("Expected to find a geometry node").0;

let vertex_stack = &model_geometry.vertex_stack;

let vertex_positions = vertex_stack
    .find(hard::BASE_VERTEX_LAYER_NAME)
    .expect("Expected to find a vertex layer")
    .as_vec_f32();

let vertex_normals = vertex_stack
    .find(soft::LAYER_NORMALS)
    .expect("Expected to find a normal layer")
    .as_vec_f32();

Missing features

• Several parsing types are not implemented, however the essental ones are.
