ratatui-ratty 🐀

A ratatui widget for placing inline 3D objects in Ratty through the Ratty Graphics Protocol.

Example

use std::io;

use ratatui_core::{buffer::Buffer, layout::Rect, widgets::Widget};
use ratatui_ratty::{ObjectFormat, RattyGraphic, RattyGraphicSettings};

fn main() -> io::Result<()> {
    let mut graphic = RattyGraphic::new(
        RattyGraphicSettings::new("assets/objects/SpinyMouse.glb")
            .id(7)
            .format(ObjectFormat::Glb)
            .animate(true)
            .scale(1.0)
            .depth(1.5)
            .rotation([0.0, 30.0, 0.0]),
    );

    // Register an existing asset by path.
    graphic.register()?;

    let mut buf = Buffer::empty(Rect::new(0, 0, 80, 24));
    (&graphic).render(Rect::new(10, 5, 24, 10), &mut buf);

    // Update transform or style in-place after placement.
    graphic.settings_mut().rotation = [0.0, 90.0, 0.0];
    graphic.settings_mut().brightness = 1.2;
    graphic.update()?;

    Ok(())
}

The widget emits RGP APC sequences into the target buffer cell. Ratty then resolves the asset and renders it as an inline 3D object anchored to that terminal region.

Payload Registration

If the object data is already in memory, register it directly instead of referring to a file path:

use std::io;

use ratatui_ratty::{ObjectFormat, RattyGraphic, RattyGraphicSettings};

fn main() -> io::Result<()> {
    let graphic = RattyGraphic::new(
        RattyGraphicSettings::new("live_draw.obj")
            .id(42)
            .format(ObjectFormat::Obj),
    );

    let obj = b"v 0 0 0\nv 1 0 0\nv 0 1 0\nf 1 2 3\n";
    graphic.register_payload(obj)?;
    Ok(())
}
