Extracted field with surface value threshold 0.0

Same field extracted with surface value threshold 0.01

Same field extracted with surface value threshold 0.1

Have tried using any other value, but it only works with 0.0. The greater the value, the greater the mess The images describe it better than I ever could :)

The triangle vertex positions could be interpolated between the cells they are in between.

By interpolation I mean like this:

To help with deciding on how detailed the density information should be, the VoxelData trait could be updated:

pub trait VoxelData: Default + Clone + Copy {
    /// The type that acts as density
    type Density: Density;
    /// How to get the density from a given data object
    //From:  fn density(&self ) -> Self::Density;
    fn density(&self, cell_size:  f32) -> Self::Density;
}

The function usage inside the library contains this information in let rot = self.current_rotation;:

This would make it possible to provide better representative density information through VoxelData by enabling the trait implementers to use the size of the iterating cube.

Hey, I spent the weekend porting your library to C++. Hope you don't mind. It is a bit of a clumsy port. I added a reference back you the original.

To help in generating UV positions I found myself in need of querying for every triangle the edge points of the cubes used to generate them.

I mean the green points in the below image:
