<para>
|
|
<function>glDispatchCompute</function> launches one or more compute
|
|
work groups. Each work group is processed by the active program object for the compute
|
|
shader stage. While the individual shader invocations within a work group are
|
|
executed as a unit, work groups are executed completely independently and in
|
|
unspecified order. <parameter>num_groups_x</parameter>, <parameter>num_groups_y</parameter>
|
|
and <parameter>num_groups_z</parameter> specify the number of local
|
|
work groups that will be dispatched in the X, Y and Z dimensions, respectively.
