+ <code class="function">glBindTexture</code> lets you create or use a named texture. Calling <code class="function">glBindTexture</code> with
+ <em class="parameter"><code>target</code></em> set to
+ <code class="constant">GL_TEXTURE_1D</code>, <code class="constant">GL_TEXTURE_2D</code>, <code class="constant">GL_TEXTURE_3D</code> or
+ <code class="constant">GL_TEXTURE_CUBE_MAP</code> and <em class="parameter"><code>texture</code></em> 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.
+ </p><p>
+ 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 <a class="citerefentry" href="glXCreateContext.xml"><span class="citerefentry"><span class="refentrytitle">glXCreateContext</span></span></a>) of the current
+ GL rendering context;
+ two rendering contexts share texture names only if they
+ also share display lists.
+ </p><p>
+ You may use <a class="citerefentry" href="glGenTextures.xml"><span class="citerefentry"><span class="refentrytitle">glGenTextures</span></span></a> to generate a set of new texture names.
+ </p><p>
+ When a texture is first bound, it assumes the specified target:
+ A texture first bound to <code class="constant">GL_TEXTURE_1D</code> becomes one-dimensional texture, a
+ texture first bound to <code class="constant">GL_TEXTURE_2D</code> becomes two-dimensional texture, a
+ texture first bound to <code class="constant">GL_TEXTURE_3D</code> becomes three-dimensional texture, and a
+ texture first bound to <code class="constant">GL_TEXTURE_CUBE_MAP</code>
+ 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 <code class="constant">GL_TEXTURE_1D</code> at GL initialization, and similarly for two-
+ and three-dimensional textures and cube-mapped textures.
+ </p><p>
+ 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.
+ </p><p>
+ A texture binding created with <code class="function">glBindTexture</code> remains active until a different
+ texture is bound to the same target, or until the bound texture is
+ deleted with <a class="citerefentry" href="glDeleteTextures.xml"><span class="citerefentry"><span class="refentrytitle">glDeleteTextures</span></span></a>.
+ </p><p>
+ 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 <code class="function">glBindTexture</code> to bind an existing named
+ texture to one of the texture targets than it is to reload the texture image
+ using <a class="citerefentry" href="glTexImage1D.xml"><span class="citerefentry"><span class="refentrytitle">glTexImage1D</span></span></a>, <a class="citerefentry" href="glTexImage2D.xml"><span class="citerefentry"><span class="refentrytitle">glTexImage2D</span></span></a>, or <a class="citerefentry" href="glTexImage3D.xml"><span class="citerefentry"><span class="refentrytitle">glTexImage3D</span></span></a>.
