# schiebung
Fast, memory-safe in-memory transform graph with time-aware lookups.
`schiebung` stores time-stamped isometries between named frames and lets you query any frame's pose relative to any other by chaining the edges. It supports lerp/slerp interpolation when the requested timestamp falls between samples, batched updates, and a URDF loader for robotics use.
Useful anywhere you have multiple coordinate systems that move relative to each other — multi-sensor fusion, simulation, motion capture, AR/VR, robotics. The closest analogue is ROS [TF2](http://wiki.ros.org/tf); `schiebung` is for projects that want the abstraction without pulling in ROS.

## At a glance
```rust
use schiebung::{BufferTree, StampedIsometry, TransformType, TransformUpdate};
let mut buffer = BufferTree::new();
buffer.update(&[
TransformUpdate::new(
"world",
"robot_base",
StampedIsometry::from_secs([0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 1.0], 0.0),
TransformType::Static,
),
])?;
let tf = buffer.lookup_latest_transform("world", "robot_base")?;
# Ok::<(), Box<dyn std::error::Error>>(())
