<p dir="ltr">* OpenGL ES 2.0 I can kind of understand, but why OpenGL 2.1 compatibility?<br>
* Why ANGLE? As far as I know this is for old cards that we already decided to stop supporting.<br>
* Why not require OpenGL ES 3.0 as a minimum when someone decides to port Blender to Android / iOS? Support for this seems pretty good.<br>
* WebGL 2 will match ES 3.0. If no one is actively working on WebGL support now, why bother with the backwards compatibility?</p>
<p dir="ltr">I really think we should be able to assume support for FBOs, VAOs, float / half-float textures, instanced draw, and not have to deal with GLSL syntax differences between versions.</p>
<p dir="ltr">How is Blend4Web affected by Blender's minimum OpenGL version? What kind of issues would there be if Blender assumed ES 3.0 minimum, while Blend4Web still targets ES 2.0?</p>
