{{FeaturePageBody | |||
|Feature open issues and risks=Chris Jones is writing the Direct3D 10/D2D texture sharing code, and will write the D3D9 composition of Basic (Cairo) cross-process layers. | |||
'''It has not yet been decided who will do this work for OpenGL on OS X and Linux.''' This may be a simple task, because we already support compositing basic shadow layers using OpenGL. | |||
|Feature users and use cases=* Draw into textures using Direct2D/D3D10, and share those to the chrome process for D3D10 composition. (Win7/Vista) | |||
* Draw into textures using Basic layers (Cairo) and share those to the chrome process for D3D9 and OpenGL composition. (WinXP/OS X/Linux) | |||
|Feature requirements=* Support sharing D3D10 textures on Windows Vista and 7. Draw into these textures using the regular path of the Direct2D backend to Cairo. Composite these Direct3D 10 shadow layers using Direct3D 10 in the chrome process. | |||
* Support compositing basic shadow layers using Direct3D 9 on Windows XP, Windows 7, and Windows Vista. | |||
* Support compositing basic shadow layers using OpenGL on OS X. | |||
* ''Optional'': Support compositing basic shadow layers using OpenGL on Linux. | |||
* No major performance regressions on any supported platform. | |||
|Feature non-goals=* Cross-process WebGL. | |||
* Anything related to the Azure API. | |||
|Feature implementation notes===== Next Steps ==== | |||
* Get Chris Jones' Direct3D 10 patches working. | |||
* Write Direct3D 9 composition of basic shadow layers. | |||
* Verify OpenGL composition of basic shadow layers on OS X. | |||
* Verify OpenGL composition of basic shadow layers on Linux. | |||
