Bug 110497 – WEBGL_compressed_texture_pvrtc needs implementation

• Status: RESOLVED
• Resolution: FIXED
• Component: WebGL

[Remi Arnaud]

WEBGL_compressed_texture_pvrtc (see URL) is in Draft stage, and is awaiting implementation to enable the community to review the extension.

WEBGL_compressed_texture_pvrtc in necessary to take advantage of specific hardware texture compression, and is used to enable content to fit in the device GPU memory, as well as optimizing for speed (smaller transfer, zero decoding time). This extension is similar to WEBGL_compressed_texture_s3tc, already implemented, that covers a lot of devices, but unfortunately is not available on all devices.
