bvh_anim

A rust library for loading .bvh files containing skeletal animation data.

⚠⚠NOTE: This library is currently alpha quality software.⚠⚠

Basic usage

To get started, add the following to your Cargo.toml:

[dependencies]
bvh_anim = "0.2"

And then, you can import the library using the use bvh_anim::*; statement in your rust files. A small example is shown below:

use bvh_anim;
use std::fs::File;

let bvh_file = File::open("./path/to/anim.bvh")?;
let bvh = bvh_anim::load(BufReader::new(bvh_file))?;

for joint in bvh.joints() {
    println!("{:#?}", joint);
}

println!("Frame time: {:?}", bvh.frame_time());

for frame in bvh.frames() {
    println!("{:?}", frame);
}

let mut out_file = File::create("./out.bvh");
bvh.write_to(&mut out_file)?;

For more information about the bvh file format and using this library, see the documentation on docs.rs.

Features

This crate has a small ffi module which allows you to parse bvh files from C code. The ffi module can be enabled with the ffi feature, and you can read the docs for it on docs.rs.

In addition, the bindings feature can be enabled to generate the C bindings using cbindgen. The bindings header is written to either $CARGO_TARGET_DIR if it is specified, or $CARGO_MANIFEST_DIR/target/include/bvh_anim/bvh_anim.h if it is not.

Contributing

This library welcomes open source contributions, including pull requests and bug reports (including feature requests).

This library aims to be the primary bvh parser in the Rust ecosystem, and aims to correctly parse a wide variety of bvh files. If you have a file which does not parse correctly, please report a bug. Parsing should always return an error on failure and never panic.
