Metal: Provoking vertex support for Metal DrawArrays Add in provoking vertex rewrite support for drawArrays command, enabling 6 dEQP tests. GLES3/functional_rasterization_flatshading_line_loop GLES3/functional_rasterization_flatshading_line_strip GLES3/functional_rasterization_flatshading_lines GLES3/functional_rasterization_flatshading_triangle_fan GLES3/functional_rasterization_flatshading_triangle_strip GLES3/functional_rasterization_flatshading_triangles This patch adds a new shader to the Provoking Vertex helper that generates draw commands for all simple data types. Fix bug in provoking vertex helper that caused reused index buffers to suffer from allocation issues. Also fix Provoking vertex for triangle fan generation Bug: angleproject:5325 Change-Id: I7a1211dfcd99329868269ea0666eef1915d487b5 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3261635 Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Kenneth Russell <kbr@chromium.org> Commit-Queue: Kyle Piddington <kpiddington@apple.com>
This folder contains shared back-end-specific implementation files. The classes
and types in renderer are not specified by GLES. They instead are common to
all the various ANGLE implementations.
See renderer_utils.h for various cross back-end utilties.
The ANGLE format class, angle::Format, works as a union
between GLES and all the various back-end formats. It can represent any type
of format in ANGLE. e.g. Formats in Vulkan that don’t exist in GLES, or DXGI
formats that don’t exist in GLES, or Windows/Android surface configs that
don’t exist anywhere else.
The glInternalFormat member of angle::Format represents the “closest” GL
format for an ANGLE format. For formats that don’t exist in GLES this will
not be exactly what the format represents.
The back-ends also define their own format tables. See the Vulkan Format table docs and the [D3D11 format table docs][D23D11FormatDocs].
DXGI formats are used in both the GL and D3D11 back-end. Therefore the generated info table lives in this common shared location.
The DXGI info table is generated by gen_dxgi_format_table.py
and sources data from dxgi_format_data.json. The
main purpose of the table is to convert from a DXGI format to an ANGLE
format, where the ANGLE format should have all the necessary information.
