When using the OpenGL ES API, there are limitations that you must be aware of when developing your applications.</p> <p>For example, the following OpenGL functionality is not present in either OpenGL ES 1.1 or OpenGL ES 2.0:</p> <ol> <li><p>There is no support for glBegin or glEnd. Use vertex arrays and vertex buffer objects instead.</p></li> <li><p>The only supported rasterization primitives are points, lines and triangles. Quads are not supported.</p></li> <li><p>There is no polynomial function evaluation stage.</p></li> <li><p>You cannot send blocks of fragments directly to individual fragment operations.</p></li> <li><p>There is no support for display lists.</p></li> </ol> <p>In addition, the following OpenGL functionality is not present in OpenGL ES 2.0:</p> <ol> <li><p>There is no support for the fixed-function graphics pipeline. You must use your own vertex and fragment shader programs.</p></li> <li><p>There is no support for viewing transforms such as glFrustumf. You must compute your own transformation matrix, pass it to the vertex shader as a uniform variable, and perform the matrix multiplication in the shader.</p></li> <li><p>There is no support for specialized functions such as glVertexPointer and glNormalPointer. Use glVertexAttribPointer instead.</p></li> </ol> </blockquote> <p>You can always refer to <a href="http://www.khronos.org/opengles/2_X/" rel="nofollow">the OpenGL ES specification</a> and see if a function / feature is supported.</p>
