d4618ea8a6 vulkan: Don't crash with overly large nodes 
... when these nodes are used as children of a complex transform nodes
and we lose the clip.

3e620a8fe5 vulkan: Split generic code off 
No need to duplicate code in shaders when it can be shared.

6d8c8199d9 vulkan: Use rounded rect APIs to improve clips 
There are a bunch of intersection APIs available these days.
Let's use them.

968ceb71d5 gsk: Add (private) gsk_rounded_rect_intersection() 
The idea is that for a rectangle intersection, each corner of the
result is either entirely part of one original rectangle or it is
an intersection point.

By detecting those 2 cases and treating them differently, we can
simplify the code to compare rounded rectangles.

7f5504bea4 vulkan: Set the initial clip rect 
Instead of rendering unclipped, set the clip region to the extents of
the current clip region.

Benjamin Otte
4b2b239550 vulkan: Only draw one rect 
Instead of emitting the render commands once per rectangle of the clip
region, just emit them once with the region's extents.

This is generally faster because it emits fewer commands to the GPU,
even though it may touch significantly more pixels.

For a proper method, we'd need to record the commands per clip rectangle
instead of emitting all of them all the time.

23c10d434c vulkan: Use CLAMP_TO_EDGE in sampler 
We don't want to clamp to the border, that causes fade-outs at the
edges.

Benjamin Otte
87c9503293 vulkan: Rewrite AA shaders to respect scale 
The border and color shaders - the ones that do AA - now multiply their
coordinates by the scale factor, which gives them better rounding
capabilities.

This in particular improves the case where they are used in fractional
scaling situations, where the scale is defined at the root element.

76634cb68b vulkan: Don't allocate no descriptor sets 
If we don't need them, exit early.

Shuts up the validation layers when running simple denos without
textures.

52eefdb7d9 vulkan: Only use a single pipeline layout 
There's no need to use 3 different ones when they are compatible.

ea9f0a3372 vulkan: Don't cull vertices 
We end up with the backside, when we scale(-1) and we still want it to
be visible, just flipped.

8561ff37c4 vulkan: Use scale factor for offscreens and fallbacks 
Previously, we just used the defaultscale factor, but now that we're
having it available in push constants, we can read it back for creating
offscreens and rendering fallbacks.

So do that.

a09580b9ef vulkan: Split scale from matrix 
Now, the scale is no longer part of the matrix. This allows shaders to
transform points by the scale which increases accuracy for antialiasing.

0511227379 vulkan: Keep the modelview as a GskTransform 
This allows doing more optimized math on it.

4183ce0b52 vulkan: Split modelview and projection 
This is adding extra work, but the benefits should become visible
in future commits.

b02e054592 vulkan: Add offset to the Vulkan clip checks 
This was forgotten when tracking the offset was added, so code was
actually selecting the wrong shaders.

8d586be693 vulkan: Add a new GskVulkanParseState 
It's a 1:1 replacement for GskVulkanPushConstants, just without the
indirection through a different file.

GskVulkanPushConstants as a struct is gone now.
The file still exists to handle the push_constants operation.
 2023-06-04 19:42:01 +02:00

94ab11b999 vulkan: Don't store push constants in RenderOp 
Instead, only store the values that are needed.

9b1dcd3872 vulkan: Split out gsk_vulkan_render_pass_append_push_constants()

c37171f4d6 vulkan: Pass values to push directly 
Don't require a GskVulkanPushConstants there.
 2023-06-04 19:42:01 +02:00
Benjamin Otte
c479f93372 vulkan: Add a static assert 
We don't want to make the push constants larger than what the spec
guarantees. And that is 128 bytes, see value for
maxPushConstantsSize in table 55 of
https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#limits-minmax

186e056c56 vulkan: Handle clip properly for offscreens 
This was broken in the last commit.

d8b9c3ae96 vulkan: Track offset in the renderpass 
This avoids emitting lots of push constant updates as most of the
transforms we have are simple translations to adjust drawing for the
next widget.

5de6f12e88 vulkan: Pass scale to offscreens 
Create offscreens with enough pixels for the given scale and ensure
the scale is passed on.

This improves text rendering on offscreens quite a bit.

5422c12577 vulkan: Clean up scale handling 
1. Use a graphene_vec2_t
2. Ensure it's always positive
3. Don't break with fallback

The scale value is nothing more than an indication of how many pixels to
assume per unit of a node.

5b93a32f90 vulkan: Remove unneeded argument 
The initial matrix can be computed as needed, so we don't need to
precompute it.

495ee1be3d vulkan: Don't explode without vertex data 
If no buffer has any vertex data (read: if nothing gets drawn), don't
try to allocate a 0 bytes buffer.

8ba5ff98aa vulkan: Don't transform the viewport rect 
We don't want to render the offscreen trnsformed, we want to render it
as-is.

We lose the correct scale factor, but that requires some separate work,
so for now it gets a bit blurry on hidpi.

34f4493c36 vulkan: Make quarks global variables 
I don't want to ensure there's a RenderPass available everywhere and
recreate the quarks in each, I just want to use them.

314923d4b5 vulkan: Split out a function 
We can now create offscreens explicitly.

d2f45dae96 vulkan: offscreens are used as color attachments 
... so set the corresponding flag.

Also name the function "new_for_offscreen()" because thats what this
function is about, "texture" is ambiguous.

3d1a607367 vulkan: Don't round corners when growing rounded rect

1be21a33d9 vulkan: Rewrite rounded rectangle to use SDF distance 
We can use this to properly compute distance in scaled situations.
We also now compute coverage with (imperfect) antialiasing.

Benjamin Otte
64bcdb713c vulkan: Start rework on shaders to allow antialiased drawing 
This introduces the rect object and adds a rect_distance() and
rect_coverage() function.

_distance() returns the signed distance tp the rectangle.
_coverage() returns the coverage of a pixel centered at that position.

Note that the pixel size is computed using dFdx/dFdy.

4a868736f9 vulkan: Render whole texture 
When the node bounds were a non-integer size, the texture would get
ceil()ed pixels, but various viewport or scissor computations might
floor() instead, leaving the right/bottom row of pixels untouched.
Make sure those functions ceil(), too.

cfeaa0ac72 renderer: return_if_fail() if the given texture size is 0
