| OpenGL ES Extension #?? |
| |
| Dependencies |
| |
| Requires OpenGL ES 2.0 |
| |
| Written against the OpenGL ES 2.0 specification. |
| |
| Overview |
| |
| This extension allows the OpenGL context to indicate if it supports drawing |
| with client-side vertex or index data. Client-side can be very inefficient |
| and unsafe, it is convenient for some users to completely disable its usage. |
| |
| New Procedures and Functions |
| |
| None |
| |
| New Tokens |
| |
| Accepted by the <cap> parameter to IsEnabled and the <pname> parameter to |
| GetBooleanv, GetIntegerv, GetFloatv, and GetInteger64v: |
| |
| CLIENT_ARRAYS_ANGLE 0x93AA |
| |
| Additions to the OpenGL ES Specification |
| |
| Add after paragraph 3 of section 2.8 "Vertex Arrays": |
| |
| If VertexAttribPointer is called while zero is bound to the ARRAY_BUFFER |
| buffer object binding point, the pointer argument is not NULL, and |
| CLIENT_ARRAYS_ANGLE is TRUE, an INVALID_OPERATION error is generated. |
| |
| Add to the end of section 2.9.1 "Vertex Arrays in Buffer Objects": |
| |
| Rendering commands that draw more than 0 primitives using enabled vertex |
| attributes with no buffer bound when CLIENT_ARRAYS_ANGLE is TRUE generate |
| an INVALID_OPERATION error. |
| |
| Add to the end of section 2.9.2 "Array Indices in Buffer Objects": |
| |
| Rendering commands that draw more than 0 primitives using index data when |
| no buffer is bound to the ELEMENT_ARRAY_BUFFER binding point when |
| CLIENT_ARRAYS_ANGLE is TRUE generate an INVALID_OPERATION error. |
