<para>

<function>glBindProgramPipeline</function> binds a program pipeline object to the current
|
||
|
|
context. <parameter>pipeline</parameter> must be a name previously returned from a call
|
||
|
|
to <citerefentry><refentrytitle>glGenProgramPipelines</refentrytitle></citerefentry>. If
|
||
|
|
no program pipeline exists with name <parameter>pipeline</parameter> then a new pipeline object
|
||
|
|
is created with that name and initialized to the default state vector.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
When a program pipeline object is bound using <function>glBindProgramPipeline</function>, any previous
|
||
|
|
binding is broken and is replaced with a binding to the specified pipeline object. If <parameter>pipeline</parameter>
|
||
|
|
is zero, the previous binding is broken and is not replaced, leaving no pipeline object bound.
|
||
|
|
If no current program object has been established by <citerefentry><refentrytitle>glUseProgram</refentrytitle></citerefentry>,
|
||
|
|
the program objects used for each stage and for uniform updates are taken from the bound program
|
||
|
|
pipeline object, if any. If there is a current program object established by <citerefentry><refentrytitle>glUseProgram</refentrytitle></citerefentry>,
|
||
|
|
the bound program pipeline object has no effect on rendering or uniform updates. When a bound program
|
||
|
|
pipeline object is used for rendering, individual shader executables are taken from its program objects.
