ANGLE back-ends

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.

ANGLE Formats

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 Format Info

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.
