How to implement marching cubes in Unity with C#

Unfortunately I rarely save source code for pet projects, otherwise I could have shown the messy code I had.

Thank you for the answer! This is what I meant by grid (quoted from first paragraph of solution here):

The fundamental problem is to form a facet approximation to an isosurface through a scalar field sampled on a rectangular 3D grid. Given one grid cell defined by its vertices and scalar values at each vertex, it is necessary to create planar facets that best represent the isosurface through that grid cell.

However, I think your description of a chunk is the same as this and what I want.

Yes, I do have a function for generating triangles. I have the whole of Paul Bourke's Polygonise source code in C#.

This clayful? If so, you know how to make what I want. I just want a box/sphere object to do the cutting/drawing of the terrain like in this game.

Thanks very much. I will try this and get back to you. I appreciate the help.

Yeah okay if you can generate triangles based on a float[,,] scalarField = new scalarField[16, 16, 16]; then all you need to do is to paint into that (add/subtract) and then regenerate the mesh

Would I use this code to generate a chunk of triangles:

 using UnityEngine;
 using System.Collections;
 
 public class example : $$anonymous$$onoBehaviour {
     public Vector3[] newVertices;
     public Vector2[] newUV;
     public int[] newTriangles;
     void Start() {
         $$anonymous$$esh mesh = new $$anonymous$$esh();
         GetComponent<$$anonymous$$eshFilter>().mesh = mesh;
         mesh.vertices = newVertices;
         mesh.uv = newUV;
         mesh.triangles = newTriangles;
     }
 }

Then add the 8 vertices of the cube/chunk. I'm not sure what to use the triangles array for though. Thanks again!

Could you explain this in more detail, please? What steps in your list would that method be in place of?
