How to make WebGL draw on a specific texture

[paulrouget]

For WebVR + immersive mode, FxR will provide a specific texture to draw on (new texture, new size).

Any recommendation on how to approach this?

A typical scenario is:

• servo renders a webpage which includes a webgl canvas
• through the webvr api, the user requests to switch to immersive mode
• FirefoxReality creates a SurfaceTexture
• Servo needs to draw on the texture

Sending the surface handle to servo's internals is not really the problem, it's more about how to swap from the initial texture to a new one.

If you take a look at servo/surfman#131, that's the code that needs to be provided with the texture I'd so it can be bound to the framebuffer.
