Should samples favour using immutable textures? #151

Open tsherif opened 7 years ago

tsherif commented 7 years ago

The spec suggests (section 3.7.6) that they should be preferred over mutable textures. If it's considered best practice, perhaps the samples should use them exclusively?

That'd be great. The memory savings on some platforms can be significant.

Shannon Woods also mentioned that she saw reduced CPU overhead in ANGLE: https://twitter.com/ShannonIn3D/status/544915451940442112

Update should be straightforward, since I don't think any of the samples are resizing textures. It might be nice to have at least one example of generating mipmaps for an immutable texture, since it's a little more involved (here's the code that handles it in PicoGL).

Just made an equivalent update to my WebGL 2 Examples: https://github.com/tsherif/webgl2examples/commit/667f69ed5b00e9f4f9f411c745a07e22334b43d9
