I wanted to clarify what I mean by fixed vs. dynamic topology. In game graphics meshes can normally be not merged smoothly because the edges and connectivity is static and holes can't be closed or created. Dynamic topology recomputes the connectivity when needed.

I wrote a bunch of compute shader code to hook into Lumen which evaluates mathematical light shapes. On the CPU side we are using perceptual filtering to pick the most important lights. It was a lot of fun! :)

I did a lot of lighting on Keeper and it was a joy to have a fully dynamic lighting system, which made shifts in areas like this easy to do. We also had custom Lumen-based lights that @p1xelcoder.bsky.social put together that helped us hit the painterly/stage lighting look we were after.

Normal polygonal meshes have a fixed topology. Roughly speaking this means the number of holes in an object can't change. Also the (explicit) surface of two meshes can't be blended smoothly into one. This is no problem for distance field morphs with implicit surfaces.

Bonus post to end the week: If you are a graphics programmer do yourself a favor and get a MIDI board. It makes the work way more tactile and fun. Full props to Matt and @aaronmjacobs.com for getting me on the MIDI train. :)

The morphs in Keeper use distance fields as an (implicit) surface representation, which makes it possible to control the distance at which the surface should lie. In other words, it’s easy to deflate or inflate objects, and meshes become easily ‘moldable’.

So what is a "distance-field"? It refers to a function that tells you, for every point in space, how far away the closest surface is and—by extension—in which direction it lies.

The experiments with surflets and voxels yielded some cool results, but it became quite obvious that distance fields were the way to go to represent the surface of morph objects (as I alluded to previously). This allowed us to implement some visually neat effects like this twist transition.

This illustrates the full process of capturing the "Essence" of a mesh to be used in a morph. The distance field is retrieved and then the mesh is projected onto the cube-shaped "screen" in order to pack its surface properties into two cubemaps.

In order to use a mesh in a morph it has to be converted first, which is done by projecting its properties (base color, normal, roughness, AO) onto a cube. The results are then packed into two cubemaps. These maps in combination with the associated distance-field comprise the "Essence" of the mesh.

I'll talk more about morphs next week, but here is a prototype called "fractal guts" which didn't make it into the game. It's perfect for Halloween though!

Ha! I totally forgot that we did one more morph experiment using space filling spheres (thanks OpenVDB!). I was planning to compute a correspondence set, so that the spheres of the different shapes can move from one to another, but we moved on to another approach. Still looks pretty cool though. :)

Between surflet and voxel morphs the former was more promising. Here is a look behind the cube-shaped curtain... Each object is represented by a cube-quad to obj-surface mapping, which then makes it straight forward to move the associated surflet between the surface locations and blend properties.

Another experiment we tried was to use (axis and surface aligned) voxels rather than surflets. The obvious benefit is that there are no holes the surface, but the voxelized look didn't fit Keeper and it was expensive to render due to the voxel density needed to make this work.
