cross domain images support

[jarben]

Just started playing with echart-gl - amazing!!!

One thing I've noticed is that you can't load images from other domains, returns:
Failed to execute 'texImage2D' on 'WebGLRenderingContext': The cross-origin image at xxxx may not be loaded.

Would it be possible to add img.crossOrigin = "Anonymous"; when loading images?

[pissang]

Yes it's the limitation of WebGL. Really bothering. I suggest you using a proxy server to load the image.

And thanks!! Any suggestion will be appreciated.

Oh, didn't realize img.crossOrigin doesn't work in WebGL, that's pity!

Just want to say one more time that this echarts-gl is so amazing! I wonder what's the roadmap around it?

[pissang]

Sorry for the miss of roadmap, it's still on my computer ;)

There are still many things to do before 1.0.0 is released. Here are some big parts.

• Transition and animation

• Integrate with brush component.

• Better view control, orthographic view.

• Events.

• Picture mode and screenshots.

And other small improments.

And the most tough part is english doc and examples ;)

[pissang]

About English doc. I'm wondering if you are interested in helping us translate the doc into English :)

[jarben]

Definitely happy to help with translation @pissang , that's this repo isn't it? https://github.com/ecomfe/echarts-doc/tree/gh-pages/en/option-gl?

Regarding roadmap, sounds great! If I can emphasise something it's the Events as it makes it more extensible. Also, handling tooltips and providing necessary data for formatters is a big one!

On a side note, any thoughts around exposing some qtek API in the similar way how graphic:[] are done? Would be awesome to play with some custom objects - 3d rectangles, texts! But's probably far beyond 1.0:)

[pissang]

So glad to hear that! That's where English doc is put. And the Chinese doc https://github.com/ecomfe/echarts-doc/tree/gh-pages/cn/option-gl . Basically we extend markdown with JavaScript template.

And about 3D graphics API. It's in the roadmap after 1.0 released, but not that far;) We will provide a component called graphicGL. Through which, users can add a cube, sphere or even load 3D models conveniently.

[jarben]

That's sounds great, looking forward to play with that!

Regarding translation, will try to allocate some time for this early in May. Also I wonder whether it's now good time for the translation when the Chinese original is still evolving? Or is the API considered almost finished?

[pissang]

That will be great! API of the finished components and features will not change much. So any time will be good time ;)
