Struct FieldEvaluator 

pub struct FieldEvaluator {
    pub gradient_eps: f32,
    pub compute_gradient: bool,
    pub compute_material: bool,
    pub min_contribution: f32,
}

Batch field evaluator — evaluates the entity’s field with optimizations.

Fields

gradient_eps: f32

Epsilon for gradient computation (central differences).

compute_gradient: bool

Whether to compute gradient (can skip if only need strength).

compute_material: bool

Whether to compute color/emission (can skip for pure MC classification).

min_contribution: f32

Minimum source contribution to consider (skip negligible sources).

Implementations

impl FieldEvaluator

pub fn strength_only() -> Self

pub fn with_gradient() -> Self

pub fn full() -> Self

pub fn evaluate(&self, entity: &MetaballEntity, point: Vec3) -> FieldSample

Evaluate the field at a single point.

pub fn evaluate_strength_at(&self, entity: &MetaballEntity, point: Vec3) -> f32

Evaluate field strength only (fast path for marching cubes classification).

pub fn sample_grid( &self, entity: &MetaballEntity, bounds_min: Vec3, bounds_max: Vec3, resolution: u32, ) -> FieldGrid

Sample the field on a regular 3D grid. Returns a flat array [z][y][x].

Trait Implementations

impl Default for FieldEvaluator

fn default() -> Self

Returns the “default value” for a type.
