8 | <code class="function">glGenTextures</code> returns <em class="parameter"><code>n</code></em> texture names in <em class="parameter"><code>textures</code></em>. | |
9 | There is no guarantee that the names form a contiguous set of integers; | |
10 | however, it is guaranteed that none of the returned names was in use | |
11 | immediately before the call to <code class="function">glGenTextures</code>. | |
12 | </p><p> | |
13 | The generated textures have no dimensionality; they assume the dimensionality | |
14 | of the texture target to which they are first bound | |
15 | (see <a class="citerefentry" href="glBindTexture.xml"><span class="citerefentry"><span class="refentrytitle">glBindTexture</span></span></a>). | |
16 | </p><p> | |
17 | Texture names returned by a call to <code class="function">glGenTextures</code> are not returned by | |
18 | subsequent calls, unless they are first deleted with | |
19 | <a class="citerefentry" href="glDeleteTextures.xml"><span class="citerefentry"><span class="refentrytitle">glDeleteTextures</span></span></a>. | |
