SideFX Houdini Meets Rust!

[SideFx Houdini](https://www.sidefx.com/) is world leading software for creating stunning visual effects for movies
and games. Apart from the main graphical interface written in C++ and Python, Houdini also provides a C interface
called [Houdini Engine](https://www.sidefx.com/products/houdini-engine/) or HAPI for short. Its goal is to bring the
power of Houdini to other DCCs (Digital Content Creation) software and game engines.

> :exclamation: A valid **commercial** Houdini Engine license is required to use this crate

# Example

```rust
use hapi_rs::Result;
use hapi_rs::session::quick_session;
use hapi_rs::parameter::*;

fn main() -> Result<()> {
    // Start a standalone engine process
    let session = quick_session(None)?;
    // Load a Houdini Asset and create a node
    let lib = session.load_asset_file("otls/hapi_geo.hda")?;
    let node = lib.create_asset_for_node("Object/hapi_geo", None)?;
    // Set the "scale" parameter
    if let Parameter::Float(parm) = node.parameter("scale")? {
        parm.set(0, 3.0)?;
        node.cook(None)?;
    }
    // Get a reference to the node's internal geometry
    let geometry = node.geometry()?.expect("geometry");
    // Save it to one of the supported geometry formats
    geometry.save_to_file("/tmp/output.fbx")?;
    Ok(())
}
```
