reflow_sdf

Signed Distance Field IR, primitives, operations, and WGSL code generation for Reflow's procedural rendering actors.

Most users should depend on reflow_rt which re-exports this crate as reflow_rt::sdf. Direct use is appropriate when writing custom procedural-geometry actors or offline SDF tools.

What it provides

• SdfNode IR: primitives (sphere, box, cylinder, torus, tube path, puddle, …), CSG operations (union, intersect, subtract, smooth variants), transforms, material slots, scene settings.
• codegen::compile — emits a ready-to-use WGSL compute shader for ray marching.
• Slot-dispatch support: material shaders from reflow_shader can plug into specific named regions of an SDF scene.

Quick glance

use reflow_sdf::{ir::*, codegen::compile};

let scene = SdfNode::Scene {
    root: Box::new(SdfNode::Primitive {
        prim: SdfPrimitive::Sphere { radius: 1.0 },
        material: None,
    }),
    settings: SceneSettings::default(),
};

let compiled = compile(&scene);
println!("{}", compiled.wgsl);

In a Reflow graph, the SDF tree is authored by tpl_sdf_* actors, then consumed by tpl_sdf_render (ray march) or tpl_sdf_marching_cubes (mesh).
