French Gameing Engineing Programmering. He/Him. The rotating chicken/duck of your dreams.

Might actually be four ducks in a trenchcoat, who knows?

Tends to goof around in Pico-8, Picotron, Blender, Godot, his own engine or more. Curious about too many thing to count. Mostly prefers low poly and big pixels, preferably with nearest neighbor interpolation.

So one of the things with Esoterica that I find intersting is by me following the broad stroked, I ended up with an infrastructure who doesn't own the entities in their world, scene or anything. Most of the API is biased towards "hands-free" management of the allocated object, with only a few helpers to decide when to actually destroy them.

Esoterica uses generated type reflection as wrappers for its own memory allocators to allocate entities, but doesn't request them from the world.

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

Mentally, I'm usually diverging from this. If an entity is in a world, its lifetime should be bound to this world. This doesn't reflect in Esoterica's design and the design I followed and suddenly, a lot of the interface might have to be redone in order to reflect this desired change.

My position on that is not totally fixed yet, I have time to reconsider, but at least I'm happy it happens now and not way later.

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

For a quick recap, here's the structure: Worlds are basically a list of scenes which contains entities and a list of world systems (who aren't aware of scenes). Worlds are the one who manage the entities' insertion, update and removal/deletion, orchestrating the entity's components and systems lifetime in the same time.

Mmh, I could actually use a sparseset to store a scene's entities. That'd make updating and global iterations faster

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

The reflexion was raised by the fact that I have nothing to track which entities requested internal state change (component or system deletion or creation), so I browse through a vector<Entity*>. No points for guessing what happens if I load the same scene 100 times.

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

I could also make line Esoterica and add callbacks on internal state change requests too but I fell this design is a bit wonky for reasons I can't grasp yet

it's still a mess but it was really fun to draw >w< a fun little experiment! Also, since the result looks good it gave me a bit of a confidence boost. maybe i'll do more~

Which match colorwise (teal + coral) with the ribbons in the background. There are also some brown-red camelia esque flowers, some gold leaves/stems and tall candles. Her gaze can be interpreted as sorrowful or longing.

Ok, it's hard to see but I implemented the drag & drop for spatial entities to easily allow reparenting with an extra bounding box displayed on both the active entity and the one the dropped entity will be reparented to.

Screenshot of my game engine showing that I'm dragging the entity "[red-diffuse-1]" into "[red-diffuse-2]" in the world debug GUI and the shown scene (a close up on PBR test spheres) shows that "[red-diffuse-1]" has its bounding box displayed in white and "[red-diffuse-2]" in pink.

Added fading distances (fades on the last meter before being culled by distance) to my engine's pointlights to alleviate the culling and rendering. It can probably help a lot with lights so small they wouldn't contribute, but they need more authoring during optimization phases. Eh.

Oooh, ohohohohoh, so they make a min/max index per z-slice ? Damn clever.

Gotta read that paper in downtime, it looks really interesting in many ways. :O

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

Update: I don't have great great numbers but implementing the z-slice range scoping did made the clustering run faster or scale better, depending on the situation of course.

In a busy scene I dropped from 1.5ms to roughly 1ms for the clustering itself. No change in the image, which is good news. The CPU cost is minimal (a few extra µs on the bigger PC), so it's all good!
Addendum: for comparison, the naive/original version would take 5ms there.
And I still haven't implemented active froxels yet

I'm using a custom fixed-size "sparse set" container that is on the stack. Mwelp.

Do you have any idea how you would "fix" generational sparse sets' slot getting exhausted (through cyclign through all generations)?

@dotstdy the thing is then I also run under the fear of total set exhaustion too now!

D16_UNORM for shadow maps should be enough, right? (CSM directional shadow currently stay on 2048/24bit)

  • 200 MB of VRAM trading for blurrier shadow, can't complain much.
Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

Down to roughly 300MB on 640x360. Consider the envmap loaded, the "bloom" mipchain and the allocated shadowmap pool and I have a rough estimate of the base memory cost.

Something I'm actually surprised is if I give a stub "application" to the engine, it actually works! It shows a black screen with imgui but it does work. So weird that I didn't plan this and yet it still works.

I also fixed the frustum culling froxel allocation which I forgot to fix (lol). Down to 29MB give or take (I'm dicing hard + a light list per frustum)

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

I forgot the exact number but I'm down to 300 MB with the scene loaded. There are obvious optimizations I could do (a float4 for vertex/instance color? Really?) but I don't have a lot more than that for now.

I really need a better allocation tracking system than just listing the loaded resources.

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

Ah yeah, I'm dicing hard indeed: 147456 frustum cells. I might opt for a per-active froxel light list allocation instead. This looks really gratuitous.

@Ronflaix@mastodon.gamedev.place avatar

Ah yeah, I'm dicing hard indeed: 147456 frustum cells. I might opt for a per-active froxel light list allocation instead. This looks really ridiculous in the current state.

Eh, it might be a good reason to add indirect dispatch too. If I can also limit the number of threads doing the whole culling like that, I could reduce the cost of the technique. Mmh

Ronflaix OP ,
@Ronflaix@mastodon.gamedev.place avatar

Oh no, it also means predictive allocation for light lists now too, so readback data, margin tuning and all. Eeeh.
