Enum SdfNode 

pub enum SdfNode {
    Leaf(Box<dyn Sdf>),
    Binary {
        op: BoolOp,
        left: Box<SdfNode>,
        right: Box<SdfNode>,
        k: f64,
    },
}

Dynamic SDF expression tree node.

Allows building complex SDF scenes at runtime without generic type nesting.

Variants

Leaf(Box<dyn Sdf>)

A leaf: arbitrary boxed SDF.

Binary

A binary combination of two nodes.

Fields

op: BoolOp

Binary operation.

left: Box<SdfNode>

Left child.

right: Box<SdfNode>

Right child.

k: f64

Blend radius (used for smooth ops).

Implementations

impl SdfNode

pub fn leaf<S: Sdf + 'static>(s: S) -> Self

Create a leaf node from any Sdf implementor.

pub fn combine(op: BoolOp, left: Self, right: Self, k: f64) -> Self

Combine two nodes with a boolean operation.

pub fn eval(&self, p: [f64; 3]) -> f64

Evaluate the SDF tree at point p.
