    <thetext>Feedback: https://bugs.webkit.org/show_bug.cgi?id=70099.
  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.)</thetext>

    <thetext>Hi,

I would like to ask you, if we can&apos;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&apos;t found the appropriate functions for it.
Any idea, suggestion?</thetext>

    <thetext>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.</thetext>

    <thetext>Apple ports would not want an OpenGL-based backend, but perhaps other ports would?</thetext>

    <thetext>I don&apos;t know Oliver&apos;s original plan. But, I think this is done by bug#75778.</thetext>
