75 Texturing maps a portion of a specified texture image
76 onto each graphical primitive for which texturing is enabled.
77 To enable and disable three-dimensional texturing, call <a href="glEnable.xml"><span class="citerefentry"><span class="refentrytitle">glEnable</span></span></a>
78 and <a href="glDisable.xml"><span class="citerefentry"><span class="refentrytitle">glDisable</span></span></a> with argument <code class="constant">GL_TEXTURE_3D</code>.
79 </p><p>
80 To define texture images, call <code class="function">glTexImage3D</code>.
81 The arguments describe the parameters of the texture image,
82 such as height,
83 width, depth,
84 width of the border,
85 level-of-detail number
86 (see <a href="glTexParameter.xml"><span class="citerefentry"><span class="refentrytitle">glTexParameter</span></span></a>),
87 and number of color components provided.
88 The last three arguments describe how the image is represented in memory.
89 </p><p>
90 If <em class="parameter"><code>target</code></em> is <code class="constant">GL_PROXY_TEXTURE_3D</code>, no data is read from <em class="parameter"><code>data</code></em>, but
91 all of the texture image state is recalculated, checked for
92 consistency, and checked
93 against the implementation's capabilities. If the implementation cannot
94 handle a texture of the requested texture size, it sets
95 all of the image state to 0,
96 but does not generate an error (see <a href="glGetError.xml"><span class="citerefentry"><span class="refentrytitle">glGetError</span></span></a>). To query for an
97 entire mipmap array, use an image array level greater than or equal to
98 1.
99 </p><p>
100 If <em class="parameter"><code>target</code></em> is <code class="constant">GL_TEXTURE_3D</code>,
101 data is read from <em class="parameter"><code>data</code></em> as a sequence of signed or unsigned bytes,
102 shorts,
103 or longs,
104 or single-precision floating-point values,
105 depending on <em class="parameter"><code>type</code></em>.
106 These values are grouped into sets of one,
107 two,
108 three,
109 or four values,
110 depending on <em class="parameter"><code>format</code></em>,
111 to form elements.
112 Each data byte is treated as eight 1-bit elements,
113 with bit ordering determined by <code class="constant">GL_UNPACK_LSB_FIRST</code>
114 (see <a href="glPixelStore.xml"><span class="citerefentry"><span class="refentrytitle">glPixelStore</span></span></a>).
115 </p><p>
116 If a non-zero named buffer object is bound to the <code class="constant">GL_PIXEL_UNPACK_BUFFER</code> target
117 (see <a href="glBindBuffer.xml"><span class="citerefentry"><span class="refentrytitle">glBindBuffer</span></span></a>) while a texture image is
118 specified, <em class="parameter"><code>data</code></em> is treated as a byte offset into the buffer object's data store.
119 </p><p>
120 The first element corresponds to the lower left corner of the texture
121 image.
122 Subsequent elements progress left-to-right through the remaining texels
123 in the lowest row of the texture image, and then in successively higher
124 rows of the texture image.
125 The final element corresponds to the upper right corner of the texture
126 image.
127 </p><p>
128 <em class="parameter"><code>format</code></em> determines the composition of each element in <em class="parameter"><code>data</code></em>.
129 It can assume one of these symbolic values:
130 </p><div class="variablelist"><dl><dt><span class="term"><code class="constant">GL_RED</code></span></dt><dd><p>
131 Each element is a single red component.
132 The GL converts it to floating point and assembles it into an RGBA element
133 by attaching 0 for green and blue, and 1 for alpha.
134 Each component is then multiplied by the signed scale factor <code class="constant">GL_c_SCALE</code>,
135 added to the signed bias <code class="constant">GL_c_BIAS</code>,
136 and clamped to the range [0,1].
137 </p></dd><dt><span class="term"><code class="constant">GL_RG</code></span></dt><dd><p>
138 Each element is a red and green pair.
139 The GL converts each to floating point and assembles it into an RGBA element
140 by attaching 0 for blue, and 1 for alpha.
141 Each component is then multiplied by the signed scale factor <code class="constant">GL_c_SCALE</code>,
142 added to the signed bias <code class="constant">GL_c_BIAS</code>,
143 and clamped to the range [0,1].

145 Each element is an RGB triple.
146 The GL converts it to floating point and assembles it into an RGBA element
147 by attaching 1 for alpha.
148 Each component is then multiplied by the signed scale factor <code class="constant">GL_c_SCALE</code>,
149 added to the signed bias <code class="constant">GL_c_BIAS</code>,
150 and clamped to the range [0,1].
151 </p></dd><dt><span class="term"><code class="constant">GL_RGBA</code></span></dt><dd></dd><dt><span class="term"><code class="constant">GL_BGRA</code></span></dt><dd><p>
152 Each element contains all four components.
153 Each component is multiplied by the signed scale factor <code class="constant">GL_c_SCALE</code>,
154 added to the signed bias <code class="constant">GL_c_BIAS</code>,
155 and clamped to the range [0,1].
156 </p></dd></dl></div><p>
157 If an application wants to store the texture at a certain
158 resolution or in a certain format, it can request the resolution
159 and format with <em class="parameter"><code>internalFormat</code></em>. The GL will choose an internal
160 representation that closely approximates that requested by <em class="parameter"><code>internalFormat</code></em>, but
161 it may not match exactly.
162 (The representations specified by <code class="constant">GL_RED</code>, <code class="constant">GL_RG</code>, <code class="constant">GL_RGB</code>,
163 and <code class="constant">GL_RGBA</code> must match exactly.)
