  I plan to using GrapichsContext3D, it seems it prefer to use, but any ideas are welcome.
  (I am a student on University of Szeged, and I would like to make it as my Bachelor Thesis.)

Hi,

I would like to ask you, if we can't rendering to a texture with GraphicsContext3D, what would you propse instead of the usage of GC3D. (We definitely have to rendering to a texture)
Or perhaps I just didn't found the appropriate functions for it.
Any idea, suggestion?

GraphicsContext3D can absolutely render to a texture. You must allocate a framebuffer object and a texture, and attach the texture to an FBO.

The Chromium port of WebKit uses the DrawingBuffer class as the back buffer for WebGLRenderingContext, which effectively does this behind the scenes. twiz@ recently added this code path.

Apple ports would not want an OpenGL-based backend, but perhaps other ports would?

I don't know Oliver's original plan. But, I think this is done by bug#75778.
