49 | <para> | |
50 | <function>glGenTextures</function> returns <parameter>n</parameter> texture names in <parameter>textures</parameter>. | |
51 | There is no guarantee that the names form a contiguous set of integers; | |
52 | however, it is guaranteed that none of the returned names was in use | |
53 | immediately before the call to <function>glGenTextures</function>. | |
54 | </para> | |
55 | <para> | |
56 | The generated textures have no dimensionality; they assume the dimensionality | |
57 | of the texture target to which they are first bound | |
58 | (see <citerefentry><refentrytitle>glBindTexture</refentrytitle></citerefentry>). | |
59 | </para> | |
60 | <para> | |
61 | Texture names returned by a call to <function>glGenTextures</function> are not returned by | |
62 | subsequent calls, unless they are first deleted with | |
63 | <citerefentry><refentrytitle>glDeleteTextures</refentrytitle></citerefentry>. | |
