3D terrain not woking with safari in macos

[xawill]

Hi, and thank you for this library which looks awesome!

I am just not sure from the readme whether the library supports the generation of a 3D terrain. Because from what I read, it is possible to provide a height map tileset, but I haven't been able to reproduce any 3D terrain in the demo. It is always a planar map.

Did I miss something ?

I am looking for something similar to Map33, but I prefer your coding style, focused on maintainability and of course written in TypeScript :)

Thank you!

Hello

The library supports 3D terrain tiles it is the main focus in this library.

You can open the example of the library and switch between modes and tile providers to experiment the multiple configurations.

Thanks a lot!

Thank you for your reply.

I think the issue is with the demo at https://tentone.github.io/geo-three. Try to load the page and check the console. A lot of "Failed to load height node data" errors display. I guess that we cannot test the 3D part of your library on the demo website due to this.

But most likely the issue is due to an error in authentication with MapBox height tiles server or something on the demo. I'll give it a try locally with my own tiles providers. Pretty sure it will work :)

The demo is not broken it is working correctly. These errors are caused by missing tiles for ocean regions and can be ignored.

Well, it doesn't work for me, over Switzerland, a very mountainous country in the Alps in Europe.

I am using Safari latest public version on macOS latest public version.

This is over Mont-Blanc (4809m):

Can you please provide a height "not shader" screenshot of these areas?

I have no way of testing with mac os, do you have any shader related error?

[xawill]

No problem. I might be able to test on my side on Windows to try to narrow down what the issue is.

Here is the screenshot you requested: Mont-Blanc area again, with height "not shader". You can also see the output of the console, which is filled with hundred of such errors (one per tile, I would guess). I have no other error (no shader issue reported).

PS: After writing this, I tested on Chrome on macOS and it works as expected (except from the gap at tiles edges, but I guess this is a complicated issue to solve, right ?):

So apparently the issue is with Safari on macOS exclusively.

[tentone]

Thanks a lot for this information this has to be fixed. The errors you're getting should not be related but i have to take a closer look maybe using a VM i can reproduce the error.

Thanks!

[xawill]

Thanks a lot. I didn't have the chance to integrate your library in my project yet, but will in the following hours/days. I will then have more extensive access to the debugger and will let you know if I can better identify the issue.

I thought at first that the issue might be related to Safari not supporting webgl2, but I don't think you use it. And I had Safari webgl2 experimental feature enabled.

I also have this issue on macOS running Firefox 89.0 (64-bit); so this isn't exclusive to Safari.

[xawill]

I didn't investigate at all, but I saw you use OffscreenCanvas a lot. This is still considered an experimental feature, is not supported by Safari and only partially by Firefox : https://developer.mozilla.org/fr/docs/Web/API/OffscreenCanvas.

[tentone]

@xawill That could be the reason for the height data to be missing.

I will patch the lib to use regular canvas object whenever OffscreenCanvas is not available.

Thanks a lot!

[tentone]

Removed the need for OffscreenCanvas in new version. Should be working correctly in safari now!

Thanks a lot!

Hi @tentone it's not working on my ipad, maybe we need to reopen this! thank you

[tentone]

Hello @laraduarte please open a new issue regarding this problem.

Include the version of the browser and OS that youre running and any content from the console please.

Thanks a lot!
