<para>
|

<function>glVertexAttribDivisor</function> modifies the rate at which generic vertex attributes advance when rendering
|
|
multiple instances of primitives in a single draw call. If <parameter>divisor</parameter> is zero, the attribute at slot
|
|
<parameter>index</parameter> advances once per vertex. If <parameter>divisor</parameter> is non-zero, the attribute advances
|
|
once per <parameter>divisor</parameter> instances of the set(s) of vertices being rendered. An attribute
|
|
is referred to as instanced if its <constant>GL_VERTEX_ATTRIB_ARRAY_DIVISOR</constant> value is non-zero.
