[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. 2021-02-24 10:58:31 +00:00			`#version 450`
[vulkan] Move oit blending into compose subpass I had debated putting the blending in the compose subpass or a separate pass but went with the separate pass originally, but it turns out that removing the separate pass gains 1-3% (5-15/545 fps in a timedemo of demo1). 2022-12-01 14:03:55 +00:00			`#extension GL_GOOGLE_include_directive : enable`
[vulkan] Implement most of the changes for cube rendering There are some missing parts from this commit as these are the fairly clean changes. Missing is building a separate set of pipelines for the new render pass (might be able to get away from that), OIT heads texture is flat rather than an array, view matrices aren't set up, and the fisheye renderer isn't hooked up to the output pass (code exists but is messy). However, with the missing parts included, testing shows things mostly working: the cube map is rendered correctly even though it's not displayed correctly (incorrect view). This has definitely proven to be a good test for Vulkan's multiview feature (very nice). 2023-01-23 02:14:06 +00:00			`#extension GL_EXT_multiview : enable`

[vulkan] Tweak the lighting to look a bit better Reduced the gamma correction a bit and increased the intensity of dynamic lights. Not sure the latter is correct, but it looks much better. 2021-03-20 10:15:06 +00:00			`c = pow (c, vec3(0.83));//FIXME make gamma correction configurable`
