How can I March Cubes - generating holes in mesh

How can I use Marching Cubes for generating holes in a 3D mesh?

To use the Marching Cubes algorithm for generating holes in a 3D mesh, follow these steps:

Divide the Space: Divide the 3D space into a grid of voxels.

Sample Vertex Positions: For each voxel, sample the density or value at the eight vertices.

Determine Triangle Configuration: Determine the triangle configuration for each voxel based on the sampled vertex positions. There are 256 possible configurations, but many are symmetrical, reducing the number to 152.

Generate the Mesh: Generate the mesh by connecting the vertices according to the determined configurations.

Create Holes: To create holes, adjust the density values or isosurface threshold to exclude certain regions, effectively creating voids in the mesh.

By following these steps, you can use the Marching Cubes algorithm to generate holes in your 3D mesh.
