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 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.
