Struct IsosurfaceExtraction 

Source 
pub struct IsosurfaceExtraction {
    pub isovalue: f64,
}
Expand description

Isosurface extraction via the Marching Cubes algorithm.

Implements the full 256-case lookup table for robust triangle generation at the specified isovalue.

Fields§

§isovalue: f64

Isovalue defining the surface (default: 0.0 for signed distance fields).

Implementations§

Source§

impl IsosurfaceExtraction

Source

pub fn new(isovalue: f64) -> Self

Create a new IsosurfaceExtraction with the given isovalue.

§Arguments
  • isovalue – the scalar value defining the isosurface
Source

pub fn extract(&self, field: &LevelSetField) -> Vec<McTriangle>

Extract the isosurface from a LevelSetField as a list of triangles.

Iterates over all cells in the grid, classifies each cube, and uses the Marching Cubes lookup table to generate triangles.

Source

pub fn count_triangles(&self, field: &LevelSetField) -> usize

Count the number of triangles in the isosurface.
