The standard GLU contains a basic set of features and capabilities.
|
||
|
|
If a company or group of companies wish to support other features,
|
||
|
|
these may be included as extensions to the GLU.

If <parameter>name</parameter> is
|

|
|
<constant>GLU_EXTENSIONS</constant>, then <function>gluGetString</function>
|
||
|
|
returns a space-separated list of names of supported GLU extensions.
|
||
|
|
(Extension names never contain spaces.)
