Corrects incorrect usage of contraction for 'it is', when possessive 'its' was required.

The underlying type of the enum cannot be fixed here due to its usage
in C code.
All the values possible in the width of the underlying type are not
valid for an enum.
Only 0 to (2*max - 1) if all enumerators are unsigned.
So the macro asks for the biggest value among the //listed// ones.
If any enumerator C is set to say `A|B`, then C would be the maximum.
(2*max-1) is used as the mask.
The warnings (for each enum modified in this commit):
GPU_vertex_buffer.h:43:1: runtime error: load of value 4294967291
which is not a valid value for type 'GPUVertBufStatus'

Following the most widely used convention for including todo's in
the code, that is: `TODO(name):`, `FIXME(name)` ... etc.
|
|
Makes it follow the functions names.
|
|
This is going to be unecessary after the GPU opengl texture backend refactor.
For now add a save/restore mechanism to leave the state untouched.
Also remove some calls where the caller would bind to particular binding
point and set the shader uniform.
|
|
No functional changes
|
|
These are not used anymore and can be replicated using the GPUBatch API.
|
|
This is a first step into removing uniforms from GPU_batch and Imm.
|
|
This is done at drawtime automatically.
|
|
This changes the drawing paradigm a bit. The VAO configuration is done
JIT-style and depends on context active shader.
This is to allow more flexibility for implementations to do optimization
at lower level.
The vao cache is now its own class to isolate the concept. It is this
class that is reference by the GLContext for ownership of the containing
VAO ids.
|
|
|
|
Also add new flags to communicate specific behavior to future backend.
|
|
We instead use a handle reference counter on the GPUVertBufs used by
the instancing batches. This make sure that if an update happens on the
GPUVertBuf used to contruct the batch, they will never have the same
memory address than the previously allocated ones (since they are still
pending deletion thanks to the refcounter).
This avoid the linear search to update the GPUBatch in the case a
batch is deleted (which was even a bad option since they could be only
cleared)
|
|
This is in order to better encapsulate / isolate the drawing code.
|
|
|
|
This remove the use of batch->program and replace it with batch->shader.
This will allow GL abstraction latter.
|
|
|
|
|
|
This is needed for the new GPU abstraction.
|
|
|
|
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

This is the unification of all overlays into one overlay engine as described in T65347.
I went over all the code making it more future proof with less hacks and removing old / not relevent parts.
Goals / Acheivements:
- Remove internal shader usage (only drw shaders)
- Remove viewportSize and viewportSizeInv and put them in gloabl ubo
- Fixed some drawing issues: Missing probe option and Missing Alt+B clipping of some shader
- Remove old (legacy) shaders dependancy (not using view UBO).
- Less shader variation (less compilation time at first load and less patching needed for vulkan)
- removed some geom shaders when I could
- Remove static e_data (except shaders storage where it is OK)
- Clear the way to fix some anoying limitations (dithered transparency, background image compositing etc...)
- Wireframe drawing now uses the same batching capabilities as workbench & eevee (indirect drawing).
- Reduced complexity, removed ~3000 Lines of code in draw (also removed a lot of unused shader in GPU).
- Post AA to avoid complexity and cost of MSAA.
Remaining issues:
- ~~Armature edits, overlay toggles, (... others?) are not refreshing viewport after AA is complete~~
- FXAA is not the best for wires, maybe investigate SMAA
- Maybe do something more temporally stable for AA.
- ~~Paint overlays are not working with AA.~~
- ~~infront objects are difficult to select.~~
- ~~the infront wires sometimes goes through they solid counterpart (missing clear maybe?) (toggle overlays on-off when using infront+wireframe overlay in solid shading)~~
Note: I made some decision to change slightly the appearance of some objects to simplify their drawing. Namely the empty arrows end (which is now hollow/wire) and distance points of the cameras/spots being done by lines.

This is done because they don't have the same update frequency. UV can be
persistent even on geometry update (ex: skinned object) but tangents
can change if the normals change.
Also the name buffer per vbo was too small to contain all names.
|
|
For clarity sake, the batch cache now uses exclusively per Loop attributes.
While this is a bit of a waste of VRAM (for the few case where per vert
attribs are enough) it reduces the complexity and amount of overall VBO
to update in general situations.
This patch also makes the VertexBuffers filling multithreaded. This make
the update of dense meshes a bit faster. The main bottleneck is the
IndexBuffers update which cannot be multithreaded efficiently (have to
increment a counter and/or do a final sorting pass).
We introduce the concept of "extract" functions/step.
All extract functions are executed in one thread each and if possible,
using multiple thread for looping over all elements.

Some statements were split across multiple lines because of their
trailing comments.
In most cases it's clearer to put the comments above.
|
|
Declaration and implementation got out of sync leading to warnings.
|
|
Rename it to GPU_batch_draw_advanced and use base instance when possible.
Also add GPU_batch_bind to bind the vao independantly of drawing commands.
|
|
|
|
GPU_vertbuf_discard to clear buffer containers in place.
GPU_BATCH_UNUSED to tag batch that are cleared and not immediatly usable.
|
|
|
|
Apply clang format as proposed in T53211.
For details on usage and instructions for migrating branches
without conflicts, see:
https://wiki.blender.org/wiki/Tools/ClangFormat

|
|
|
Move free callback call to GPU_batch_discard to prevent the crash.
The issue was that clearing can happen after referencing to an instance
buffer and that's perfectly legal.

Until now, Orcos were computed by the gpu (GLSL) and were not taking into
account the modifier stack (breaking orco for deformed mesh).
Now Orco is now computed on CPU but only if a modifier stack is present.
Tagging that an ORCO layer is present is done via a 4th component, which is
a waste of memory/bandwidth. Best would be to do the same as auto attrib
color space and save a bool uniform somewhere but for now it's too
disruptive.

While \file doesn't need an argument, it can't have another doxy
command after it.
|
|
The struct name is descriptive,
this isn't going to be confused with other variables.
|
|
Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

Select clipping now works when x-ray is disabled.

BF-admins agree to remove header information that isn't useful,
