This is for completion and to be used by the new draw manager.
|
|
This allows finding missing binds more easily as the missing binds slots
won't be populated with previous texture binds.
|
|
Just like the name suggest, this adds a way to draw a series of proceduraly
positioned triangles using and indirect buffer.

This is often needed and somehow cumbersome to set up. This will allow some
code simplifications.

This function was not used for anything other than mat4. This
was because of a limitation of the DRW module/
This makes it cleaner for the GLSL and also less tempting to use
it for other unconventional purpose.

This was caused by the recent changes made to the way we handle matrix
copies. The matrix copy assumed that the uniform iteration was the same
as creation order. But this was far from true. The reality was that
the iterator was reverse for `unichunk` but not for `unichunk->uniforms`
so this was recreating wrong matrix.
I rewrote this part to always use reverse iteration and fix the
copy destination.
Also I simplified the code making the assumption this won't be used for
anything else than mat4.

- Metal uniform array compatibility in DRW module.
- Guard OpenGL-specific workarounds and flushes behind GPU_type_matches_ex API guard. Add further render boundaries for render paths called outside of the main loop.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

This patch will use compute shaders to create the VBO for hair.
The previous implementation uses transform feedback.
Timings before: between 0.000069s and 0.000362s.
Timings after: between 0.000032s and 0.000092s.
Speedup isn't noticeable by end-users. The patch is used to test
the new compute shader pipeline and integrate it with the draw
manager. Allowing EEVEE, Workbench and other draw engines to
use compute shaders with the introduction of `DRW_shgroup_call_compute`
and `DRW_shgroup_vertex_buffer`.
Future improvements are possible by generating the index buffer
of hair directly on the GPU.
NOTE: that compute shaders aren't supported by Apple and still use
the transform feedback workaround.

This patch will use compute shaders to create the VBO for hair.
The previous implementation uses tranform feedback.
Timings master (transform feedback with GPU_USAGE_STATIC between 0.000069s and 0.000362s
Timings transform feedback with GPU_USAGE_DEVICE_ONLY. between 0.000057s and 0.000122s
Timings compute shader between 0.000032 and 0.000092s
Future improvements:
* Generate hair Index buffer using compute shaders: currently done single threaded on CPU, easy to add as compute shader.

This patch will apply the view transform when a movie clip is used as
camera background image. It does this by rendering the image in the
color buffer when it needs the view transform. For other images it uses
the overlay buffer.

This patch allows the user to type a property name into the
Attribute node, which will then output the value of the property
for each individual object, allowing to e.g. customize shaders
by object without duplicating the shader.
In order to make supporting this easier for Eevee, it is necessary
to explicitly choose whether the attribute is varying or uniform
via a dropdown option of the Attribute node. The dropdown also
allows choosing whether instancing should be taken into account.
The Cycles design treats all attributes as one common namespace,
so the Blender interface converts the enum to a name prefix that
can't be entered using keyboard.
In Eevee, the attributes are provided to the shader via a UBO indexed
with resource_id, similar to the existing Object Info data. Unlike it,
however, it is necessary to maintain a separate buffer for every
requested combination of attributes.
This is done using a hash table with the attribute set as the key,
as it is expected that technically different but similar materials
may use the same set of attributes. In addition, in order to minimize
wasted memory, a sparse UBO pool is implemented, so that chunks that
don't contain any data don't have to be allocated.
The back-end Cycles code is already refactored and committed by Brecht.

Following the most widely used convention for including todo's in
the code, that is: `TODO(name):`, `FIXME(name)` ... etc.
|
|
The Draw State now needs to be in sync with what the selection
code set. We query the state just before locking it.
|
|
This wraps the functionality used to speedup EEVEE volumetrics.
This touches the rendering code of EEVEE as it should fix a mis-usage of
the GL barrier. The barrier changed type and location, removing an
unused barrier.
|
|
This makes more sense as this module has more to it than just
GL extensions.
|
|
This is just a cleanup to isolate the internals of the vertbuf.
This adds some getters to avoid refactor of existing code.
|
|
This also make the validation quicker by tracking the currently
bound slots.
|

This is related to the Vulkan port T68990.
This is a full cleanup of the Framebuffer module and a separation
of OpenGL related functions.
There is some changes with how the default framebuffers are handled.
Now the default framebuffers are individually wrapped inside special
GLFrameBuffers. This make it easier to keep track of the currently bound
framebuffer state and have some specificity for operations on these
framebuffers.
Another change is dropping the optimisation of only configuring the
changed attachements during framebuffers update. This does not give
any benefits and add some complexity to the code. This might be brought
back if it has a performance impact on some systems.
This also adds support for naming framebuffers but it is currently not
used.

In recent refactoring {a9f2ebb21508} an issue was introduced that the
opengl rasterizer would be disabled when only writing to a stencil
buffer.
This fix adds stencil writing to the write mask and set it. This makes
the write map not evaluate to GPU_WRITE_NONE and the rasterizer will be
enabled in `GLStateManager::set_write_mask`.

This avoids the misleading inheritance.

This follows the GPU module naming of other buffers.
