opengl-es-2.0 - 包含整个 OpenGL ES 2.0 状态的结构

Question

有没有人有一个 C 结构，它的成员描述了整个 OpenGL ES 2.0 状态？它看起来像这样：

struct OpenGLES20State
{
  int activeTexture;
  bool scissorEnabled;
  Rectangle scissorRectangle;
  bool stencilEnabled;
  int stencilFunc;
  int stencilOpFail;
  int stencilOpDFail;
  int stencilOpDPass;
  //
  // and a lot more...
  //
}

Answer 1

You can create this structure by carefully working with OpenGL ES 2 specification available from Khronos: http://www.khronos.org/opengles/2_X/

Also, interesting place to look for a similar implementation may be Mesa3D library source code.
