Here’s a replacement Demo.cs that works in Unity. The library should work with it.
Attach to a GameObject and set the material (I used a defaut).
using System;
using UnityEngine;
using Net3dBool;
public class Demo : MonoBehaviour
{
public Material ObjMaterial;
public Net3dBool.Solid mesh;
public Net3dBool.Color3f[ ] getColorArray(int length, Color c)
{
var ar = new Net3dBool.Color3f[length];
for (var i = 0; i < length; i++)
ar = new Net3dBool.Color3f(c.r, c.g, c.b);
return ar;
}
public void Start()
{
var box = new Net3dBool.Solid(Net3dBool.DefaultCoordinates.DEFAULT_BOX_VERTICES,
Net3dBool.DefaultCoordinates.DEFAULT_BOX_COORDINATES,
getColorArray(Net3dBool.DefaultCoordinates.DEFAULT_BOX_VERTICES.Length, Color.red));
var sphere = new Net3dBool.Solid(Net3dBool.DefaultCoordinates.DEFAULT_SPHERE_VERTICES,
Net3dBool.DefaultCoordinates.DEFAULT_SPHERE_COORDINATES,
getColorArray(Net3dBool.DefaultCoordinates.DEFAULT_SPHERE_VERTICES.Length, Color.red));
sphere.scale(0.68, 0.68, 0.68);
var cylinder1 = new Net3dBool.Solid(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES,
Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_COORDINATES,
getColorArray(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES.Length, Color.green));
cylinder1.scale(0.38, 1, 0.38);
var cylinder2 = new Net3dBool.Solid(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES,
Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_COORDINATES,
getColorArray(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES.Length, Color.green));
cylinder2.scale(0.38, 1, 0.38);
cylinder2.rotate(Math.PI / 2, 0);
var cylinder3 = new Net3dBool.Solid(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES,
Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_COORDINATES,
getColorArray(Net3dBool.DefaultCoordinates.DEFAULT_CYLINDER_VERTICES.Length, Color.green));
cylinder3.scale(0.38, 1, 0.38);
cylinder3.rotate(Math.PI / 2, 0);
cylinder3.rotate(0, Math.PI / 2);

tmp = modeller.getDifference();

tmp = modeller.getDifference();

tmp = modeller.getDifference();
mesh = tmp;
MeshFilter mf = gameObject.AddComponent ();
Mesh tmesh = new Mesh();
int mlen = mesh.getVertices().Length;
Vector3 [ ] vertices = new Vector3[mlen];
for(int i=0; i<mlen; i++)
{
Net3dBool.Point3d p = mesh.getVertices();
vertices = new Vector3((float)p.x, (float)p.y, (float)p.z);
}
tmesh.vertices = vertices;
tmesh.triangles = mesh.getIndices ();
int clen = mesh.getColors ().Length;
Color [ ] clrs = new Color[clen];
for (int j=0; j<clen; j++) {
Net3dBool.Color3f c = mesh.getColors()[j];
clrs[j] = new Color((float)c.r, (float)c.g, (float)c.b);
}
tmesh.colors = clrs;
tmesh.RecalculateNormals();
mf.mesh = tmesh;
MeshRenderer mr = gameObject.AddComponent ();
mr.materials = new Material[1];
mr.materials[0] = ObjMaterial;
mr.material = ObjMaterial;
}
}
)
