Struct LevelSetBoolean 

pub struct LevelSetBoolean;

Boolean operations on level-set fields via min/max composition.

All operations create a new LevelSetField with the same grid layout as field_a. The fields must have identical grid dimensions, spacing, and origin.

Implementations

impl LevelSetBoolean

pub fn union(field_a: &LevelSetField, field_b: &LevelSetField) -> LevelSetField

Union of two level-set fields: φ = min(φ_a, φ_b).

Corresponds to the union of the two implicit surfaces.

Arguments

• field_a – first operand
• field_b – second operand (must have same grid as field_a)

pub fn intersection( field_a: &LevelSetField, field_b: &LevelSetField, ) -> LevelSetField

Intersection of two level-set fields: φ = max(φ_a, φ_b).

Corresponds to the intersection of the two implicit surfaces.

Arguments

• field_a – first operand
• field_b – second operand (must have same grid as field_a)

pub fn difference( field_a: &LevelSetField, field_b: &LevelSetField, ) -> LevelSetField

Difference A − B: φ = max(φ_a, −φ_b).

Corresponds to removing the region of field_b from field_a.

Arguments

• field_a – base operand
• field_b – region to subtract

pub fn complement(field_a: &LevelSetField) -> LevelSetField

Complement (negation): φ = −φ_a.

Flips the inside/outside classification of the level-set.

Arguments

• field_a – the level-set field to negate

pub fn smooth_union( field_a: &LevelSetField, field_b: &LevelSetField, k: f64, ) -> LevelSetField

Smooth minimum blend (C¹ union): φ = smin(φ_a, φ_b, k).

Produces a smooth blend at the union boundary with blend radius k.

Arguments

• field_a – first operand
• field_b – second operand
• k – blend radius (larger k → smoother blend)
