pb_CSG provides an interface in the CSG class for creating new meshes from boolean operations. Each function (Union, Subtract, Intersect) accepts 2 gameObjects: the left and right side. A new mesh is returned.
Example use:
// Include the library
using Parabox.CSG;
...
// Initialize two new meshes in the scene
GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
sphere.transform.localScale = Vector3.one * 1.3f;
// Perform boolean operation
Model result = CSG.Subtract(cube, sphere);
// Create a gameObject to render the result
var composite = new GameObject();
composite.AddComponent<MeshFilter>().sharedMesh = result.mesh;
composite.AddComponent<MeshRenderer>().sharedMaterials = result.materials.ToArray();
Result:
