   Okay, here we go. Fixed that issue with some advice from: https://0fps.net/2013/07/03/ambient-occlusion-for-minecraft-like-worlds/

   Included a screenshot of what it looks like when I deliberately do it the wrong way, and one with all three forms of lighting and occlusion. XD

     Hmm, no, still needs some work. :/

     Trying to fix ambient occlusion.

     ...It's a work in progress. XD

     Got my ambient lighting drawing, and in the right places! The built in ambient occlusion isn't working correctly, and I need to write actual propagation algorithms for it, but still! Progress! XD

     Alright, actually drawing lighting. It draws in the wrong place, and in the wrong way, but it draws!

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:42 JST Angle

     Anyway, I managed to implement a bunch of lighting channels stuffed into a long. No propagation algorithm yet, but that can wait, right now I'm implementing the code to actual draw this lighting.

     Yeah I'm gonna start simple. I can upgrade to spherical harmonics or whatever later if I want to. XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:44 JST Angle

     Alright, doing some code cleanup and then I'm going to implement ambient voxel lighting, I think. Not sure exactly how I want to do it - my freind mentioned doing something fancy with spherical harmonics, and that sounds really cool, but also maybe I'll leave that for later? :/

     Okay, got my point shadows working well! Not even giving me shadow acne. XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:46 JST Angle

     in reply to

     I don't have the point shadows doing what I want them to do yet, but I'm making progress. In other news though, this is apparently the 100th Omnicraft screenshot I've saved to share on mastodon. XD

     Still working on point shadows, but I got multiple directional lights, with shadows, working properly.

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:48 JST Angle

     No wait, those are the directional shadows. Well, nvm then. XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:49 JST Angle

     Now I'm working on point shadows, and I'm most of the way through implementing it. It works surprisingly well, considering it's not finished. XD

     Okay, was doing my scaling matrices wrong, good to know. Anyway, I got light volumes working! XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:51 JST Angle

     in reply to

     Back to working on light volumes now. Trying to get some Icosahedrons in the right places, at the right sizes - but, they don;t want to scale, for whatever reason. They'll translate, they'll even rotate, but I try and pass a scaling matrix for the model matrix, they just ignore it. :/

     Finally got my shadowmaps working! XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:53 JST Angle

     So close, and yet so far away... :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:54 JST Angle

     in reply to

     Well, I think I got the shadow maps drawing correctly. Now I just need to use them in my lighting shader properly. I think I'm almost there? XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:55 JST Angle

     in reply to

     Alright, most of the way through cascading shadow maps I think? That is, it should be working already, but it ain't. But, hopefully I'm just a bug fix or two away... XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:56 JST Angle

     in reply to

     Yeah, light volumes, shadow mapping, both of these things are a real challenge. I think I'm slowly figuring it out, but damn if it ain't hard! XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:57 JST Angle

     in reply to

     Yeah so I had to fix attenuation, but I got that working. Trying to figure out light volumes now - not so easy, as it turns out. :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:58 JST Angle

     in reply to

     Haven't got light volumes yet, but here's directional light, and in theory i got attenuation working too? :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:30:59 JST Angle

     Well, here's blending. Now I just need to figure out light volumes.

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:00 JST Angle

     in reply to

     Lol no wait, first I want to do light columes and blending. Then, sunlight! XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:01 JST Angle

     in reply to

     Doing sunlight! Seems like it should be easy enough?

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:02 JST Angle

     in reply to

     Now I just need to decide what to do next. I'm thinking wither shadowcasting, or sunlight? :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:03 JST Angle

     in reply to

     Oh, and it looks like i forgot to make it take landscape color into account. So, here's a reddish blueish light with that fixed! XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:04 JST Angle

     in reply to

     Hmm. So, I wanted it to light per-texel, and it does... But I'm also getting some kind of weird z-tearing or whatever. I managed to cut it down to a reasonable level, I think i can leave it here for now. Though I should try and figure out what causes it eventually. The shader doesn't seem to like me flooring values or something. :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:05 JST Angle

     in reply to

     Or, I can just discard the lighting shader fragments anywhere there isn't anything to draw. :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:06 JST Angle

     in reply to

     I fixed the depth buffer for things in front of the terrain, so i can draw block outlines again. Now I just need to add masking so it doesn't cover the sky in darkness and I'll be good to go. XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:07 JST Angle

     in reply to

     And now with some actual lighting! Still needs a LOT of work, but, progress!

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:08 JST Angle

     in reply to

     Okay, now it's much closer. Still missing the actual lighting, and it overrides the skybox and the block outline... But, progress!

     Hey, it works! Wrong, but it works. XD

     Well, I think I'm most of the way through? Still figuring out lighting though. :/

     Oooooooh shit, no, that does not play nice with my mesh optimization algorithm at ALL. IIIII'm gonna need to rethink some things... XD

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:13 JST Angle

     in reply to

     Of course, now I need to figure out what the hell I'm going to do with these values. Pass them into the shader somehow, obviously, but how? The shader doesn't like longs, and frankly I don't think i need to give it the whole long anyway, but that means I need to figure out what I'm translating one of those longs into before I pass it into the shader. Just an int, maybe? One fourth for each color, and the last fourth for sky color? :/

   • Angle (angle@anticapitalist.party)'s status on Friday, 13-Jan-2023 07:31:14 JST Angle

     Yeah fuck it, I'm gonna use longs. Double the memory, but I think that's manageable.
