Seems I just can’t quit Sword of Moonlight! Earlier in September I made up my mind to work on the MHM files that are counterpart to the MSM files from last month. No one really knows what these acronyms mean. I hazard to guess Map Hull Model, and who knows for the S in MSM. Sculpture? Possibly its Japanese.

I thought it’d be a small project, because there is — or ought to be — far fewer MHM to MSM files. I added value to the exteriors set by fitting it together vertically, forming terraces, that look like a strip mine. This is something users like to do with the odd set that is experimental compared to the interiors. It’s the only one that isn’t a level of From Software’s remake of King’s Field included with SOM, an enticement doubling as a demonstration.

As a result of my endeavoring to do good by Sword of Moonlight in the back half of 2017 two remarkable things came about:

The first came out of left field. Something I’d thought about doing for years: it applies a meager form of classical antialiasing to the shapes cutout by black parts of texture-mapped images. This counters pixelation. I ended up doing this now because of a secondary interest in “cross-platform” text rendering; that is a challenging problem. I was considering an approach that made me curious about what this would look like, and I thought I should try to do this first, since it was simpler.

There is virtually nothing on the WWW about classical antialiasing, much less examples in software. I found some resources for implementing a relatively modern approximation called MLAA. It is not really suitable for this application, but the results were a marked improvement, so I’ve made it the default technology going forward.

The next development would be a major undertaking to finally seal the cracks I opened up in 2015 when I developed the modern replacement technology for the earlier antialiasing extension. Note that these kinds of “antialiasing” are unrelated. The new development smooths precise, purely black and white edges; whereas the “antialiasing extension” produces straight geometric lines in 3D images, and does so by preventing aliasing in the first place, akin to how MSAA works or worked, but leverages time and our eyes, so that our silicon computers can be used for more interesting things.
