vmc

An asynchronous implementation of the Virtual Motion Capture Protocol in Rust.

While this crate is intended specifically for Virtual Motion Capture, it can also be used as an implementation of the Open Sound Control protocol which VMC is based on.

Examples

See examples/ for more detailed examples.

Performer

use vmc::{
	VMCApplyBlendShapes, VMCBlendShape, VMCModelState, VMCResult, VMCStandardVRMBlendShape, VMCState, VMCTime
};

#[tokio::main]
async fn main() -> VMCResult<()> {
	let socket = vmc::performer!("127.0.0.1:39539").await?;
	loop {
		socket
			.send(VMCBlendShape::new(VMCStandardVRMBlendShape::Joy, 1.0))
			.await?;
		socket.send(VMCApplyBlendShapes).await?;
		socket.send(VMCState::new(VMCModelState::Loaded)).await?;
		socket.send(VMCTime::elapsed()).await?;
	}
}

Marionette

use tokio_stream::StreamExt;
use vmc::{VMCMessage, VMCResult};

#[tokio::main]
async fn main() -> VMCResult<()> {
	let mut socket = vmc::marionette!("127.0.0.1:39539").await?;
	while let Some(packet) = socket.next().await {
		let (packet, _) = packet?;
		for message in vmc::parse(packet)? {
			match message {
				VMCMessage::BoneTransform(transform) => {
					println!("\tTransform bone: {} (pos {:?}; rot {:?})", transform.bone, transform.position, transform.rotation)
				}
				_ => {}
			}
		}
	}

	Ok(())
