Sunlight meets color, and I’m hooked. Proof that subsurface scattering deserves more hype. #flowers #mobilegame #cozygame #flowerlovers #homeplant #sandbox #simulationgames #subsurfacescattering

Sometimes, the best things grow when you stop trying to control them. This tangled beast I grew up last week, thinkscreenshotsaturday is the best time to share it. #screenshotsaturday #flowers #mobilegame #cozygame #flowerlovers #homeplant #sandbox #simulationgames #bee #honeybee

There are, of course, plenty of limitations (obvious and not-so-obvious) - I’ll dive into those next time 😉 And finally, here are a few fresh in-game shots (and remember - the game is still about flowers! 🌸) (16/16)

Bonus point: the same approach also gives cheap multi-point (and areal) lights support - in forward rendering, on mobile! 🎉🎉🎉 (15/16)

Using this system, I built a small set (7 types) of analytical AO shapes that cover most in-game dynamic props. The result is much more detailed and believable than the old texture-based version. Left = old. Right = new. (13/16)

Side views of cylindrical shapes also needed separate math (and again, the right image shows the ray-traced reference). (12/16)

Rectangular shapes are trickier since they have hard edges. I ended up with a slightly different, yet still cheap, function that models the visibility per rectangle size - same logic as with cylinders. (11/16)

For a top-down projected cylinder, that relation is proportional to arctan(D/R), where R is the cylinder radius. This separation (vertical+horizontal) produces results that are visually close to ray-traced truth - see the right image (distances and heights are not correlated on the images): (10/16)

The core 2D case is actually simple: Imagine a flat occluder of width 2W(from -W to W) standing at height H. The occlusion function looks like: (cos(arctan((x - W)/H)) + cos(arctan((-x - W)/H))) / 2 + 1 In other words - the sum of light coming from the left and right gaps around the occluder. (7/16)

Florisium @florisium.bsky.social · 07/10/2025

For the first version of the system, I used static textures to approximate the occlusion shape of some typical primitives. Just 3 texture types - pulled on for every moving object in the game (could be more than 1 shape per object). It worked!

4. Apply some shadow (occlusion) pattern on the area and draw the resulting geometry. 5. And yeah - do the above for every occlusion-receiver pair 😅 (4/16)

Florisium @florisium.bsky.social · 07/10/2025

So, I went back in time and revived a classic: blob shadows - the technique used in early 3D games that often mimicked ambient occlusion rather than true shadows. (3/16)

Florisium @florisium.bsky.social · 07/10/2025

A bit technical thread 🧵 I’ve been improving the in-game ambient occlusion system - and ended up with something I call: Blob-based Analytical Ambient Occlusion on Primitives Here’s what it does to the final image: (more examples later in the thread) (1/16)
