+ attribute to be modified.</p></dd><dt><span class="term"><em class="parameter"><code>v</code></em></span></dt><dd><p>Specifies a pointer to an array of values to

+ applications can modify with standard API entry points (color,
+ normal, texture coordinates, etc.). The
+ <code class="function">glVertexAttrib</code> family of entry points
+ allows an application to pass generic vertex attributes in
+ numbered locations.</p><p>Generic attributes are defined as four-component values
+ that are organized into an array. The first entry of this array
+ is numbered 0, and the size of the array is specified by the
+ implementation-dependent constant
+ <code class="constant">GL_MAX_VERTEX_ATTRIBS</code>. Individual elements
+ of this array can be modified with a
+ <code class="function">glVertexAttrib</code> call that specifies the
+ index of the element to be modified and a value for that
+ element.</p><p>These commands can be used to specify one, two, three, or
+ all four components of the generic vertex attribute specified by
+ <em class="parameter"><code>index</code></em>. A <code class="function">1</code> in the
+ name of the command indicates that only one value is passed, and
+ it will be used to modify the first component of the generic
+ vertex attribute. The second and third components will be set to
+ 0, and the fourth component will be set to 1. Similarly, a
+ <code class="function">2</code> in the name of the command indicates that
+ values are provided for the first two components, the third
+ component will be set to 0, and the fourth component will be set
+ to 1. A <code class="function">3</code> in the name of the command
+ indicates that values are provided for the first three
+ components and the fourth component will be set to 1, whereas a
+ <code class="function">4</code> in the name indicates that values are
+ provided for all four components.</p><p>The letters <code class="function">s</code>,
+ <code class="function">f</code>, <code class="function">i</code>,
+ <code class="function">d</code>, <code class="function">ub</code>,
+ <code class="function">us</code>, and <code class="function">ui</code> indicate
+ whether the arguments are of type short, float, int, double,
+ unsigned byte, unsigned short, or unsigned int. When
+ <code class="function">v</code> is appended to the name, the commands can
+ take a pointer to an array of such values. The commands
+ containing <code class="function">N</code> indicate that the arguments
+ will be passed as fixed-point values that are scaled to a
+ normalized range according to the component conversion rules
+ defined by the OpenGL specification. Signed values are
+ understood to represent fixed-point values in the range [-1,1],
+ and unsigned values are understood to represent fixed-point
+ values in the range [0,1].</p><p>OpenGL Shading Language attribute variables are allowed to
+ be of type mat2, mat3, or mat4. Attributes of these types may be
+ loaded using the <code class="function">glVertexAttrib</code> entry
+ points. Matrices must be loaded into successive generic
+ attribute slots in column major order, with one column of the
+ matrix in each generic attribute slot.</p><p>A user-defined attribute variable declared in a vertex
+ shader can be bound to a generic attribute index by calling
+ <a class="citerefentry" href="glBindAttribLocation.xml"><span class="citerefentry"><span class="refentrytitle">glBindAttribLocation</span></span></a>.
+ This allows an application to use more descriptive variable
+ names in a vertex shader. A subsequent change to the specified
+ generic vertex attribute will be immediately reflected as a
+ change to the corresponding attribute variable in the vertex
+ shader.</p><p>The binding between a generic vertex attribute index and a
+ user-defined attribute variable in a vertex shader is part of
+ the state of a program object, but the current value of the
+ generic vertex attribute is not. The value of each generic
+ vertex attribute is part of current state, just like standard
+ vertex attributes, and it is maintained even if a different
+ program object is used.</p><p>An application may freely modify generic vertex attributes
+ that are not bound to a named vertex shader attribute variable.
+ These values are simply maintained as part of current state and
+ will not be accessed by the vertex shader. If a generic vertex
+ attribute bound to an attribute variable in a vertex shader is
+ not updated while the vertex shader is executing, the vertex
+ shader will repeatedly use the current value for the generic
+ vertex attribute.</p><p>The generic vertex attribute with index 0 is the same as
+ the vertex position attribute previously defined by OpenGL. A
+ <a class="citerefentry" href="glVertex2.xml"><span class="citerefentry"><span class="refentrytitle">glVertex2</span></span></a>,
+ <a class="citerefentry" href="glVertex3.xml"><span class="citerefentry"><span class="refentrytitle">glVertex3</span></span></a>,
+ or
+ <a class="citerefentry" href="glVertex4.xml"><span class="citerefentry"><span class="refentrytitle">glVertex4</span></span></a>
+ command is completely equivalent to the corresponding
+ <code class="function">glVertexAttrib</code> command with an index
+ argument of 0. A vertex shader can access generic vertex
+ attribute 0 by using the built-in attribute variable
+ <em class="parameter"><code>gl_Vertex</code></em>. There are no current values
+ for generic vertex attribute 0. This is the only generic vertex
+ attribute with this property; calls to set other standard vertex
+ attributes can be freely mixed with calls to set any of the
+ other generic vertex attributes.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="notes"></a><h2>Notes</h2><p><code class="function">glVertexAttrib</code> is available only if
+ the GL version is 2.0 or greater.</p><p>Generic vertex attributes can be updated at any time. In
+ particular, <code class="function">glVertexAttrib</code> can be called
+ between a call to
+ <a class="citerefentry" href="glBegin.xml"><span class="citerefentry"><span class="refentrytitle">glBegin</span></span></a>
+ and the corresponding call to
+ <a class="citerefentry" href="glEnd.xml"><span class="citerefentry"><span class="refentrytitle">glEnd</span></span></a>.</p><p>It is possible for an application to bind more than one
+ attribute name to the same generic vertex attribute index. This
+ is referred to as aliasing, and it is allowed only if just one
+ of the aliased attribute variables is active in the vertex
+ shader, or if no path through the vertex shader consumes more
+ than one of the attributes aliased to the same location. OpenGL
+ implementations are not required to do error checking to detect
+ aliasing, they are allowed to assume that aliasing will not
+ occur, and they are allowed to employ optimizations that work
+ only in the absence of aliasing.</p><p>There is no provision for binding standard vertex
+ attributes; therefore, it is not possible to alias generic
+ attributes with standard attributes.</p></div><div class="refsect1" lang="en" xml:lang="en"><a id="errors"></a><h2>Errors</h2><p><code class="constant">GL_INVALID_VALUE</code> is generated if
