Move the material resources binding inside the

Problem here was that layer_collection_objects_sync wasn't called when
the holdout property is updated due to frame change, so the changed
visibility flag was never applied to ob->base_flag.
Turns out there's no real reason to handle the per-object holdout
property through the layer system. So, instead of merging both the
layer holdout and object holdout into base_flag and checking that
from the render engines, only handle the layer holdout (which can't
be animated, so no issue here) through base_flag and explicitly also
check the object holdout in the render engines.

These were only a normalized copy of the XY axes of the inverse viewmat.
But since the viewmatrix is always normalized we can use it directly.

This avoid dependency with the draw view.

This is part of the effor to simplify the View struct in order to implement
multiview rendering.
The CameraTexCoFactors being only valid for a single view, and being only
used in very few places, it make sense to move it to the engine side.

This also removes the need to compute the persmat and saves some memory
from the `ViewInfos` struct. This is needed to allow multiview support.
Initial testing found no major performance regression during vertex

Fix for T101438
Clamping the mip seems to always set it to 9.0.
I couldn't find an alternative way to avoid triggering the error (ie. min(mip, 9.0)).
In any case, the results with this patch applied look the same to the (correct) ones on AMD.
And, since clamping the max mip to a hardcoded value could result in resolution-depended behavior, I guess disabling the clamp should be ok anyway.

Rewrite PBVH draw to allocate attributes into individual VBOs.
The old system tried to create a single VBO that could feed
every open viewport. This required uploading every color and
UV attribute to the viewport whether needed or not, often exceeding
the VBO limit.
This new system creates one VBO per attribute. Each attribute layout is
given its own GPU batch which is cached inside the owning PBVH node.
Notes:
* This is a full C++ rewrite. The old code is still there; ripping it out
can happen later.
* PBVH nodes now have a collection of batches, PBVHBatches, that keeps
track of all the batches inside the node.
* Batches are built exclusively from a list of attributes.
* Each attribute has its own VBO.
* Overlays, workbench and EEVEE can all have different attribute
layouts, each of which will get its own batch.

This is required by the Metal backend to perform flushing of temporary objective-C resources. This is implemented as a global autoreleasepool, and is to ensure consistency such that all rendering operations, whether called via events, or via main loop will be within an autoreleasepool.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

This reverts commit 34051fcc12f388375697dcfc6da53e9909058fe1.
Although for normal use this doesn't make a difference. But when working with
huge scenes and volumetrics + NVIDIA it made a work-around not possible anymore.
For the heist production we added a fix on the render-farm (enable GPU workarounds).
{rB34051fcc12f388375697dcfc6da53e9909058fe1} made another work-around not

On NVIDIA volumetric resolve failed for large production scenes.
The result would remove most color from the final render. The cause
seems to be a faulty driver.
This change ported the fragment shader to a compute shader which
would select a different compiler branch and didn't show the error.

This replaces the direct shader uniform layout declaration by a linear
search through a global buffer.
Each instance has an attribute offset inside the global buffer and an
attribute count.
This removes any padding and tighly pack all uniform attributes inside
a single buffer.
This would also remove the limit of 8 attribute but it is kept because of
compatibility with the old system that is still used by the old draw
manager.

This was caused by un-wanted normalization. This is a requirement of
the MikkTspace. The issue is that g_data.N is expected to be normalized
by many other functions and overriden by bump displacement.
Adding a new global variable containing the interpolated normal fixes the
issue AND make it match cycles behavior better (mix between bump and
interpolated normal).

GPUCapabilities expansion.
- Adding in compatibility paths to support minimum per-vertex strides for vertex formats. OpenGL supports a minimum stride of 1 byte, in Metal, this minimum stride is 4 bytes. Meaing a vertex format must be atleast 4-bytes in size.

- 3D texture size safety check added as a general capability, rather than being in the gl backend only. Also required for Metal.

Use lowercase rgba channel names which still by-passes lossy nature
of DWA compression and which also keeps external compositing tools
happy.
Thanks Steffen Dünner for testing this patch!
Differential Revision: https://developer.blender.org/D15834

The DWA compression code in OpenEXR has hardcoded rules which decides
which channels are lossy or lossless. There is no control over these
rules via API.
This change makes it so channel names of xyzw is used for cryptomatte
passes in Cycles. This works around the hardcoded rules in the DWA code
making it so lossless compression is used. It is important to use lower
case y channel name as the upper case Y uses lossy compression.
The change in the channel naming also makes it so the write code uses
32bit for the cryptomatte even when saving half-float EXR.
Fixes T96933: Cryptomatte layers saved incorrectly with EXR DWA compression
Fixes T88049: Cryptomatte EXR Output Bit Depth should always be 32bit

The viewport compositor crashes when it is disabled then enabled after
the compositor node tree is edited.
This happens because the compositor engine uses the view_update callback
of the draw engine type to detect changes in the node tree and reset its
state for future evaluation. However, the draw manager only calls the
view_update callback for enabled engines, so the compositor never
receives the needed updates to properly reset its state and then crashes
at draw time.
This patch call the view_update callback for all registered engines
regardless if they are enabled or not, that way, they always receive
the potentially important updated needed to maintain a correct state.
Aside from the compositor engine, this change affects the EEVEE and
Workbench engines because they are the only engines that utilizes this
callback. However, both of them only reset a flag that is checked at
draw time. So the change should have no side effects. For the EEVEE
engine, we just add a null check in case it was not instanced, while
Workbench already have the appropriate null check.

Metaball, curve, text, and surface objects use the geometry component
system to add evaluated mesh object instances to the dependency graph
"for render engine" iterator. Therefore it is unnecessary to process
those object types in these loops-- it would either be redundant work
or a no-op.
|
|
With the ultimate goal of simplifying drawing and evaluation,
this patch makes the following changes and removes code:
- Use `Mesh` instead of `DispList` for evaluated basis metaballs.
- Remove all `DispList` drawing code, which is now unused.
- Simplify code that converts evaluated metaballs to meshes.
- Store the evaluated mesh in the evaluated geometry set.
This has the following indirect benefits:
- Evaluated meshes from metaball objects can be used in geometry nodes.
- Renderers can ignore evaluated metaball objects completely
- Cycles rendering no longer has to convert to mesh from `DispList`.
- We get closer to removing `DispList` completely.
- Optimizations to mesh rendering will also apply to metaball objects.
The vertex normals on the evaluated mesh are technically invalid;
the regular calculation wouldn't reproduce them. Metaball objects
don't support modifiers though, so it shouldn't be a problem.
Eventually we can support per-vertex custom normals (T93551).

This is a complete rewrite of the draw debug drawing module in C++.
It uses `GPUStorageBuf` to store the data to be drawn and use indirect
drawing. This makes it easier to do a mirror API for GPU shaders.
The C++ API class is exposed through `draw_debug.hh` and should be used
when possible in new code.
However, the debug drawing will not work for platform not yet supporting
`GPUStorageBuf`. Also keep in mind that this module must only be used
in debug build for performance and compatibility reasons.
