<para>

<function>glBindTexture</function> lets you create or use a named texture. Calling <function>glBindTexture</function> with
|
||
|
|
<parameter>target</parameter> set to
|
||
|
|
<constant>GL_TEXTURE_1D</constant>, <constant>GL_TEXTURE_2D</constant>, <constant>GL_TEXTURE_3D</constant> or
|
||
|
|
<constant>GL_TEXTURE_CUBE_MAP</constant> and <parameter>texture</parameter> set to the name
|
||
|
|
of the new texture binds the texture name to the target.
|
||
|
|
When a texture is bound to a target, the previous binding for that
|
||
|
|
target is automatically broken.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
Texture names are unsigned integers. The value zero is reserved to
|
||
|
|
represent the default texture for each texture target.
|
||
|
|
Texture names and the corresponding texture contents are local to
|
||
|
|
the shared display-list space (see <citerefentry><refentrytitle>glXCreateContext</refentrytitle></citerefentry>) of the current
|
||
|
|
GL rendering context;
|
||
|
|
two rendering contexts share texture names only if they
|
||
|
|
also share display lists.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
You may use <citerefentry><refentrytitle>glGenTextures</refentrytitle></citerefentry> to generate a set of new texture names.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
When a texture is first bound, it assumes the specified target:
|
||
|
|
A texture first bound to <constant>GL_TEXTURE_1D</constant> becomes one-dimensional texture, a
|
||
|
|
texture first bound to <constant>GL_TEXTURE_2D</constant> becomes two-dimensional texture, a
|
||
|
|
texture first bound to <constant>GL_TEXTURE_3D</constant> becomes three-dimensional texture, and a
|
||
|
|
texture first bound to <constant>GL_TEXTURE_CUBE_MAP</constant>
|
||
|
|
becomes a cube-mapped texture. The state of a one-dimensional texture
|
||
|
|
immediately after it is first bound is equivalent to the state of the
|
||
|
|
default <constant>GL_TEXTURE_1D</constant> at GL initialization, and similarly for two-
|
||
|
|
and three-dimensional textures and cube-mapped textures.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
While a texture is bound, GL operations on the target to which it is
|
||
|
|
bound affect the bound texture, and queries of the target to which it
|
||
|
|
is bound return state from the bound texture. If texture mapping is active
|
||
|
|
on the target to which a texture is bound, the bound texture is used.
|
||
|
|
In effect, the texture targets become aliases for the textures currently
|
||
|
|
bound to them, and the texture name zero refers to the default textures
|
||
|
|
that were bound to them at initialization.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
A texture binding created with <function>glBindTexture</function> remains active until a different
|
||
|
|
texture is bound to the same target, or until the bound texture is
|
||
|
|
deleted with <citerefentry><refentrytitle>glDeleteTextures</refentrytitle></citerefentry>.
|
||
|
|
</para>
|
||
|
|
<para>
|
||
|
|
Once created, a named texture may be re-bound to its same original target as often as needed.
|
||
|
|
It is usually much faster to use <function>glBindTexture</function> to bind an existing named
|
||
|
|
texture to one of the texture targets than it is to reload the texture image
|
||
|
|
using <citerefentry><refentrytitle>glTexImage1D</refentrytitle></citerefentry>, <citerefentry><refentrytitle>glTexImage2D</refentrytitle></citerefentry>, or <citerefentry><refentrytitle>glTexImage3D</refentrytitle></citerefentry>.
|
||
|
|
For additional control over performance, use
|
||
|
|
<citerefentry><refentrytitle>glPrioritizeTextures</refentrytitle></citerefentry>.
