+ <code class="function">glBindBuffer</code> lets you create or use a named buffer object. Calling <code class="function">glBindBuffer</code> with
+ <em class="parameter"><code>target</code></em> set to
+ <code class="constant">GL_ARRAY_BUFFER</code>, <code class="constant">GL_ELEMENT_ARRAY_BUFFER</code>, <code class="constant">GL_PIXEL_PACK_BUFFER</code> or
+ <code class="constant">GL_PIXEL_UNPACK_BUFFER</code> and <em class="parameter"><code>buffer</code></em> set to the name
+ of the new buffer object binds the buffer object name to the target.
+ When a buffer object is bound to a target, the previous binding for that
+ target is automatically broken.
+ </p><p>
+ Buffer object names are unsigned integers. The value zero is reserved, but
+ there is no default buffer object for each buffer object target. Instead, <em class="parameter"><code>buffer</code></em> set to zero
+ effectively unbinds any buffer object previously bound, and restores client memory usage for that buffer object target.
+ Buffer object names and the corresponding buffer object contents are local to
+ the shared display-list space (see <a class="citerefentry" href="glXCreateContext.xml"><span class="citerefentry"><span class="refentrytitle">glXCreateContext</span></span></a>) of the current
+ GL rendering context;
+ two rendering contexts share buffer object names only if they
+ also share display lists.
+ </p><p>
+ You may use <a class="citerefentry" href="glGenBuffers.xml"><span class="citerefentry"><span class="refentrytitle">glGenBuffers</span></span></a> to generate a set of new buffer object names.
+ </p><p>
+ The state of a buffer object immediately after it is first bound is an unmapped zero-sized memory buffer with
+ <code class="constant">GL_READ_WRITE</code> access and <code class="constant">GL_STATIC_DRAW</code> usage.
+ </p><p>
+ While a non-zero buffer object name is bound, GL operations on the target to which it is
+ bound affect the bound buffer object, and queries of the target to which it is bound return state
+ from the bound buffer object. While buffer object name zero is bound, as in the initial state,
+ attempts to modify or query state on the target to which it is bound generates an
+ <code class="constant">GL_INVALID_OPERATION</code> error.
+ </p><p>
+ When vertex array pointer state is changed, for example by a call to
+ <a class="citerefentry" href="glNormalPointer.xml"><span class="citerefentry"><span class="refentrytitle">glNormalPointer</span></span></a>,
+ the current buffer object binding (<code class="constant">GL_ARRAY_BUFFER_BINDING</code>) is copied into the
+ corresponding client state for the vertex array type being changed, for example
+ <code class="constant">GL_NORMAL_ARRAY_BUFFER_BINDING</code>. While a non-zero buffer object is bound to the
+ <code class="constant">GL_ARRAY_BUFFER</code> target, the vertex array pointer parameter that is traditionally
+ interpreted as a pointer to client-side memory is instead interpreted as an offset within the
+ buffer object measured in basic machine units.
+ </p><p>
+ While a non-zero buffer object is bound to the <code class="constant">GL_ELEMENT_ARRAY_BUFFER</code> target,
+ the indices parameter of <a class="citerefentry" href="glDrawElements.xml"><span class="citerefentry"><span class="refentrytitle">glDrawElements</span></span></a>,
+ <a class="citerefentry" href="glDrawRangeElements.xml"><span class="citerefentry"><span class="refentrytitle">glDrawRangeElements</span></span></a>, or
+ <a class="citerefentry" href="glMultiDrawElements.xml"><span class="citerefentry"><span class="refentrytitle">glMultiDrawElements</span></span></a> that is traditionally
+ interpreted as a pointer to client-side memory is instead interpreted as an offset within the
+ buffer object measured in basic machine units.
+ </p><p>
+ While a non-zero buffer object is bound to the <code class="constant">GL_PIXEL_PACK_BUFFER</code> target,
