On my machine, this reduces incremental compilation time after an edit of
`rendering_server.h` by 1s, and paves the way for more decoupling in
rendering code.
Removes RS as a dependency in `project_settings.cpp` (which was a bug,
`core` shouldn't include `servers`). This doesn't have a big impact on
incremental rebuild time by itself.
Also move helper `get_splash_stretched_screen_rect` to RenderingServerTypes.
A number of headers in the codebase included `rendering_server.h` just for
some enum definitions. This means that any change to `rendering_server.h` or
one of its dependencies would trigger a massive incremental rebuild.
With this change, we decouple a number of classes from `rendering_server.h`,
greatly speeding up incremental rebuilds for that area.
On my machine, this reduces incremental compilation time after an edit of
`rendering_server.h` by 60s (from 2m57s).
This helps remove dependencies on RasterizerGLES3 in many files, which is
useful as RasterizerGLES3 basically includes everything, so it brings a lot
of transient includes.
Previously, each mesh was paired up with the first N of each Omni- and Spot-lights.
Now each light is scored based on its distance to the mesh, energy, and range.
The new code uses a heap to track the best N lights (of each type) for predictability.
Always declares FOG variable regardless of fog state. Previously, only declared
fog if FOG_DISABLED was undefined. This caused errors if the code tried to
write to fog later. Exists as a dummy variable when unused.

Also optimize all tonemappers to perform less calculations per-pixel.
Note: unlike `white`, `agx_white` is limited to a minimum of `2.0` and defaults to `16.29`. When using a RGB10A2 render buffer, `agx_white` will be ignored and a value of `2.0` will be used instead to ensure good behavior on the Mobile renderer.
Previously, some messages indicating a lack of support were errors
instead of warnings. Some messages were also not shown when running
a release export template.
- Use "renderer" terminology consistently instead of "rendering method".
Reverts the default value of Environment.glow_hdr_threshold from 0.0
back to 1.0 to restore the expected glow appearance in existing projects.
The default was inadvertently changed from 1.0 to 0.0 in PR #110077,
which caused glow effects to render dramatically different across all
rendering methods (Forward+, Mobile, and GL Compatibility). This broke
backward compatibility with existing projects like the Kenney 3D
Platformer starter kit.
Changed files:
- scene/resources/environment.h
- servers/rendering/storage/environment_storage.h
- drivers/gles3/effects/glow.h
- drivers/gles3/rasterizer_scene_gles3.cpp
- doc/classes/Environment.xml
Setting the value back to 1.0 aligns with documented recommendations
and restores visual consistency.
Fixes#112469
Mobile devices are typically bandwidth bound which means we need to do as few texture samples as possible.
They typically use TBDR GPUs which means that all rendering takes place on special optimized tiles. As a side effect, reading back memory from tile to VRAM is really slow, especially on Mali devices.
This commit uses a technique where you do a small blur while downsampling, and then another small blur while upsampling to get really high quality glow. While this doesn't reduce the renderpass count very much, it does reduce the texture read bandwidth by almost 10 times. Overall glow was more texture-read bound than memory write, bound, so this was a huge win.
A side effect of this new technique is that we can gather the glow as we upsample instead of gathering the glow in the final tonemap pass. Doing so allows us to significantly reduce the cost of the tonemap pass as well.
