    Read data from Buffer object in openGL ES2.0

    I need to read data from buffer object in OpenGL ES2.0. I am using QGLfunctions and it is not possible to use glMapBufferRange. Is there any other way?

    Normally there are glGetBufferSubData or the ordinary glMapBuffer, both of which also exist in ES 2.0, but it looks like QGLFunctions does not wrap those. You could get the function pointer manually with QGLContext::getProcAddress.
