Implementations

impl MarchingCubesExtractor

pub fn extract( field: &dyn Fn(Vec3) -> f32, bounds_min: Vec3, bounds_max: Vec3, resolution: u32, threshold: f32, ) -> ExtractedMesh

Extract the threshold isosurface of field over the box, sampling resolution cells along each axis. Normals are the field’s gradient, so they are exact for a smooth field rather than averaged from faces.

pub fn extract_with( field: &dyn Fn(Vec3) -> f32, shade: &dyn Fn(Vec3) -> (Vec4, f32), bounds_min: Vec3, bounds_max: Vec3, resolution: u32, threshold: f32, ) -> ExtractedMesh

As extract, with a second function giving each vertex a colour and an emission.

pub fn extract_entity(entity: &MetaballEntity) -> ExtractedMesh

Extract a metaball entity’s surface at its own threshold and resolution, coloured by its sources.
