Using 2 framebuffer, if the temp textures are the same across redraws,
we can avoid the setup cost.
|
|
There was a missing clamp in `dof_slight_focus_coc_tile_get()`
and a couple of wrongly handled corner cases.
|

This replace the previous square rings approach by sampling a disk the
footprint of the search area. This avoids sampling in areas in corners
where there isn't any weight.
This results in much less samples needed to acheive a good enough result.
The max number of samples for an area of 11x11 px is hard coded to 16 and
still gives good results with the final clamp.
The number of samples is adaptative and is scaled by the search area (max
CoC).
The High Quality Slight Defocus is not required anymore. If there is a
quality parameter to add, it would be sample count option. But I consider
the temporal stability enough for viewport work and render can still
render many full scene samples. So I don't see a need for that yet.

This adds anti-flicker pass to the slight focus region by using the
temporaly stable output from stabilize pass.
This also fixes the bilateral weight factor which was reversed.
|
|
This was caused by a missing synchronization.
The background gather pass was writting to the same occlusion texture
before the end of the scatter draw.

This implement a full TAA pass on the depth of field input.
An history buffer is kept for each view needing Depth of field.
This uses a swap with a `TextureFromPool` in order to not always 2
textures allocated.
Since this uses luma weighting without any input, the firefly parameter is
now obsolete and has been removed.
There is some tiny difference with the Film TAA so the implementation is
mostly copy pasted.
Also this implementation uses a LDS cache to speedup the TAA computations.

This moves the slight focus max in tile from the setup pass to the
resolve pass. This reduces complexity as there is no need for an extra
component in the tile textures.
This also avoids skipping any pixels and makes sure the local max matches
the dispatched local group size. This should make the resolve pass a little
bit faster.

This is a port of the previous implementation but using compute
shaders instead of using the raster pipeline for every steps.
Only the scatter passes is kept as a raster pass for obvious performance
reasons.
Many steps have been rewritten to take advantage of LDS which allows faster
and simpler downsampling and filtering for some passes.
A new stabilize phase has been separated from another setup pass in order
to improve it in the future with better stabilization.
The scatter pass shaders and pipeline also changed. We now use indirect
drawcall to draw quads using triangle strips primitives. This reduces
fragment shader invocation count & overdraw compared to a bounding
triangle. This also reduces the amount of vertex shader invocation
drastically to the bare minimum instead of having always 3 verts per
4 pixels (for each ground).
