Naming conventions

The naming conventions for OpenGL® ES methods are the same as those for standard OpenGL®. For example:

  • javax.microedition.khronos.opengles.GL10.glClear(int mask)
  • javax.microedition.khronos.opengles.GL10.glLoadMatrixf(FloatBuffer m)

Fixed-point methods are named with an x suffix. For example:

  • javax.microedition.khronos.opengles.GL10.glLoadMatrixx(IntBuffer m)

Constants are named using the same syntax and values as standard OpenGL. For example:

  • javax.microedition.khronos.opengles.GL10.GL_TEXTURE0
