Sharing textures across threads.

[Nayan]

Hi,

I have been trying to share textures across 2 threads in android native code. Below is what I am trying to achieve,

In non-ui thread, I create a texture, bind it as a FBO and render onto this texture (using glDraw* calls).

In UI thread, I try to blit this texture onto screen.

I tried EGLContext sharing mechanism to share the texture across threads (by passing UI thread EGLContext as share texture argument to eglCreateTexture in non-ui thread). However, I do not see any output on screen, and don't even get any GL_ERROR messages!

What is the ideal way to share textures across threads? Any example code -snippets?

Thanks,

Well, 

I have never actually did it, but when reading about OpenGL ES i stepped across this:

https://developer.apple.com/library/ios/#documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/ConcurrencyandOpenGLES/ConcurrencyandOpenGLES.html#//apple_ref/doc/uid/TP40008793-CH409-SW2

While this obviously is not for Android, I still think it has useful, generic knowledge about the subject you're interested in. Hope it helps ;)

Best Regards,

Artur
