iOS support?

[y-ich]

Hi.

I am very sorry that your nice weblas does not work on iOS Safari since iOS Safari does not support WEBGL_color_buffer_float.
Is it hard for weblas to support half precision?
iOS Safari seems to support half float fully.
Please give me your suggestion.

Thanks.

Thanks for the feedback. Could you elaborate more on the scenario that generates the problem?

Here are my current understandings. If these deviate from your experience, please inform.

• Non-pipeline usage should be fine on IOS.
• Pipeline usage requires support for rendering to floating point textures.

I expect the second case to be resolved with implementation and widespread availability of WebGL 2.0. For more information see the Khronos Group WebGL 2.0 Announcement (more specifically, pages 8 and 14).

Sorry for my misunderstanding.

What I knew later is that iOS Safari does not support even WEBGL_color_buffer_half_float.
So you can not initialize buffer by float or half float on your WebGL#bindOutputTexture.

So I think,

• Even non-pipeline usage may not work fine on IOS.
• WebGL 2.0 will resolve this issue.

Thank you for your efforts. I am looking for WebGL 2.0.

Closing for now. Reopen if WebGL 2.0 doesn't address these issues.
