[vulkan] Implement lighting and compose passes Lighting doesn't actually do lights yet, but it's producing pixels. Translucent seems to be working (2d draw uses it), and compose seems to be working.

[vulkan] Move non-specific lighting code out of Vulkan The parsing of light data from maps is now in the client library, and basic light management is in scene. Putting the light loading code into the Vulkan renderer was a mistake I've wanted to correct for a while. The client code still needs a bit of cleanup, but the basics are working nicely.

[vulkan] Load the map's lights into an array It's not used yet as work needs to be done to better support generic entities, but this is the next step to real-time lighting (though, to be honest, I expect it will be too slow to be usable).

[vulkan] Up the light limit to 768 For now, at least (I have some ideas to possibly reduce the numbers and also to avoid the need for actual limits). I've seen gmsp3v2 use over 500 lights at once (it has over 1300), and I spent too long figuring out that weird light behavior was due to the limit being hit and lights getting dropped (and even longer figuring out that more weird behavior was due to the lack of shadows and the world being too bright in the first place).

[vulkan] Create shadow maps and basic data I will definitely need to look into sparse images later (2.3GB for marcher) but the shadow map images, views and matrices are created.
2021-04-29 11:54:38 +00:00
[vulkan] Rework lighting model to be more algebraic This leaves only the one conditional in the shader code, that being the distance check. It doesn't seem to make any noticeable difference to performance, but other than explosion sprites being blue, lighting quality seems to have improved. However, I really need to get shadows working: marcher is just silly-bright without them, and light levels changing as I move around is a bit disconcerting (but reasonable as those lights' leaf nodes go in and out of visibility).
