Function transvoxel::extraction::extract_from_field

pub fn extract_from_field<D, F>(
    field: F, 
    block: &Block, 
    threshold: D, 
    transition_sides: TransitionSides
) -> Mesh where
    D: Density,
    F: ScalarField<D>, 

Extracts an iso-surface Mesh for a ScalarField

Arguments:

• field: the density field
• block: the world zone for which to extract, and its subdivisions count
• threshold: density value defining the iso-surface
• transition_sides: the set of sides of the block which need to be adapted to neighbour double-resolution blocks (twice the subdivisions)
