Description Kenneth Russell 2020-11-18 18:45:06 PST
https://www.khronos.org/registry/webgl/extensions/WEBGL_draw_instanced_base_vertex_base_instance/ and https://www.khronos.org/registry/webgl/extensions/WEBGL_multi_draw_instanced_base_vertex_base_instance/ are draft WebGL extensions offering the BaseVertex / BaseInstance functionality commonly supported by lower-level graphics APIs, including OpenGL.

These extensions are well supported in ANGLE, supported in Chromium behind a flag, and need to be similarly exposed in WebKit's WebGL implementation behind a flag in order to demonstrate to the WebGL working group that they're supportable in multiple browser implementations.
