.SH "NAME"

\fIvaobj\fR
.RS 4
Specifies the name of the vertex array object for
\fBglVertexArrayBindingDivisor\fR
function\&.
.RE

\fIbindingindex\fR

The index of the binding whose divisor to modify\&.

.SH "DESCRIPTION"
.PP
\fBglVertexBindingDivisor\fR
and
\fBglVertexArrayBindingDivisor\fR
modify the rate at which generic vertex attributes advance when rendering multiple instances of primitives in a single draw command\&. If
\fIdivisor\fR
is zero, the attributes using the buffer bound to
\fIbindingindex\fR
advance once per vertex\&. If
\fIdivisor\fR
is non\-zero, the attributes advance once per
\fIdivisor\fR
instances of the set(s) of vertices being rendered\&. An attribute is referred to as
\fIinstanced\fR
if the corresponding
\fIdivisor\fR
value is non\-zero\&.
.PP
\fBglVertexBindingDivisor\fR
uses currently bound vertex array object , whereas
\fBglVertexArrayBindingDivisor\fR
updates state of the vertex array object with ID
\fIvaobj\fR\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIbindingindex\fR
is greater than or equal to the value of
\fBGL_MAX_VERTEX_ATTRIB_BINDINGS\fR\&.
.PP
\fBGL_INVALID_OPERATION\fR
by
\fBglVertexBindingDivisor\fR
is generated if no vertex array object is bound\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated by
\fBglVertexArrayBindingDivisor\fR
if
\fIvaobj\fR
is not the name of an existing vertex array object\&.
