The year started with an eye-candy update, and now it ends with one: butterflies, new flowers, new scene composition, and the return of falling leaves.

I've been working on a 3rd revision to my engine, which shrinks the
#voxels
and gives an 8x (512 cubic) detail increase, among a dozen other improvements in world gen and view distance. The scene composition and lighting isn't quite there yet, but here's a preview of the updates.

Rendering is now 10x faster on average, which allowed me to double (8x volumetric) the flower detail and implement proper ray traced soft shadows, AO and specular highlights. The core design is almost complete, so a full tour should be soon (tm).

The last few months of

have been about taking our small, fixed

Some gravity-defying vegetation in a procgen test today that looked cool enough to share. The actual worlds won't look exactly like this, but this does give a pretty solid clue as to what you can expect.

Unrealistically strong god rays + unrealistic collection of trees = cozy scene. Now we just need some unrealistic color vibrancy and we'll be all set.

Hello friends. I spent this past weekend experimenting with training a neural network to generate 2D tile maps - or more specifically Zelda Oracle of Seasons maps - and wrote a blog post on the process and results.

After bringing back global illumination that uses a new technique, I tweaked the terrain gen to create something a bit more "epic" and found what might be my favorite screenshot of this project so far. Can't wait to see waterfalls.

After going through the insane amount of feedback I received over the past few weeks, I've decided to shelf the micro-voxel goal.
Instead, the optimizations gained from those experiments will be put forth towards the "pixel art" style that so many people said they preferred.

The only downside to having volumetric clouds is that standing on the ground and waving some cloth around doesn't seem all that cool in comparison.

Here is a shallow outline of how everything ties together. It's based around a game design that to this day is still unannounced, but it will allow for easy modding and I hope to share it soon. The engine will be ripe for sharing/licensing but don't have more info on that yet.

For clarity, this was made on the engine from ~February of this year. Sometimes I get in the mood to build every so often though, and until the new stuff is ready, this is the version I play.

I think this is what Bob Ross's trees would've looked like in 3D. I now need the leaves rustling in the wind, god rays, falling leaves, tall grass, flowers, water streams, and VR. :')

Excuse the flickering since I don't know *quite* how to Vulkan well yet, but I spent the weekend coming up with a tree growth system. Leaves, environmental envelopes, roots and branch variation to-do, but I do like this quite a bit.

There were other factors that went into this decision too, ultimately boiling down to the gameplay possibilities and end-user experience being much better this way. Trying to maintain two separate art styles is also overly ambitious, and tiny voxels can always be revisited later.

Because there were so many experimental designs in the project up to this point, I've been building a new codebase designed around these realigned goals. It focuses using C/C++ for the heavy lifting and C#/.NET 5.0 for nearly all the content and front-end.

Instead of working on irradiance caching I decided to get colors into the Crytek Sponza scene and play with a flash light. 4 bounces, 262k photons here. The final two steps will make this look noiseless (hopefully!)

I spent the past week reading up on

Part of the reason it took so long is designing it be as low-bandwidth and error-forgiving as possible. This is planned to be a part of multiplayer, which is actually coming up on the list of major features.

I give you dual marching cubes applied in a linear fashion! Super easy to implement, guaranteed to be manifold (ignoring topological ambiguity cases), allows for vertex snapping and allows chunks to be processed independently.

Spent a weekend working on a very experimental and different lighting model that doesn't use voxels or ray tracing, so here's an area light flying around a cornell box (only received light is shown). I'll share more details later as I get this working better.

At some point during (A)PIC, you have a smooth grid populated with density values from the particles, and you can treat this as a level set to either run MC on, or ray march. There is no metaballs or fancy screenspace SDF functions needed.

This is a rather crude approximation of screen space irradiance cache points, but it runs pretty quickly in a single pass and can be easily controlled by an error. Here it averages around ~10K points.

What if instead of a voxel octree, we used an adaptive tetrahedral hierarchy to accelerate ray (and cone!) tracing? The surface would still use triangles, which means RTX acceleration, and the scene would still remain volumetric for simulation. I might explore this further.

Here's ESVO "cone" tracing. Unfortunately it's not very usable beyond some based LOD, and it's *extremely* slow so I'll have to ditch it and go with something like GigaVoxels that supports interpolation and mostly pointerless tracing.

Soft voxel shadows (16spp, not randomized so noise-free) and color blending. Next up is probably going to be some vegetation and tree growth.
