Trying out the map generator with the following code:

                let map = DensityMap::new(extent.width as usize, extent.height as usize, 1, raw_data).unwrap();
                let settings = GenerateDensityMeshSettings {
                    points_separation: 16.0.into(),
                    keep_invisible_triangles: false,
                    ..Default::default()
                };
                // create live density mesh.
                let mut live = LiveDensityMesh::new(map, settings);
                // perform initial processing.
                live.process_wait().unwrap();

The map is 2K by 16K. I waited for more than an hour for a release build, it hasn't finished.
Here is the test file -

(I wasn't able to upload the lossless PNG version, since it's above 10Megs)

The following questions need answering:

• what are the reasonable values?
• how does one or the other affect performance / computational complexity?

Right now if you want to update part of the mesh, you have to split it into chunks and update whole chunk on input data change.

It would be very beneficial for real time destructible meshes to update only the parts where new density/height map points to.

First results so far aren't very convincing.
See kvark/vange-rs#188 for the screenshot and the code.

Does density-mesh expect a height map at all? It has a DensityMap that I'm constructing, but I don't have a density per pixel, I have a height. So maybe I'm not using this right at all.
With the settings I got so far, it takes some time to build the mesh, and it doesn't look nearly correct. It's close to random.
