facett-simview/examples/native.rs

//! The Simulate viewer in a native window, over the in-process mock (no server):
//!
//! ```text
//! cargo run --release -p facett-simview --example native -- 110000
//! cargo run --release -p facett-simview --example native --features gpu -- 110000
//! ```
//!
//! With `--features gpu` the 3D cloud draws on the shared instanced GPU cloud renderer
//! (installed here from eframe's render state, as facet-wrapped does in the browser);
//! without it the CPU painter draws a depth-strided sample.
