reflow_sdf 0.2.0

//! SDF (Signed Distance Function) intermediate representation and WGSL code generation.
//!
//! This crate provides the building blocks for procedural geometry rendering
//! through Reflow's actor graph. Each actor contributes an [`SdfNode`] to a tree,
//! and the [`codegen`] module compiles the tree to a complete WGSL ray marching shader.
//!
//! # Architecture
//!
//! ```text

//! # Modules
//!
//! - [`ir`] — SDF node types (primitives, operations, transforms, materials)
//! - [`codegen`] — Compile SDF IR tree to WGSL shader source
//! - [`primitives`] — CPU-side SDF evaluation (for bounding, picking, tests)
