48 | Requests the internal storage format of the texture image. The most | |
49 | current version of the SGI implementation of GLU does not check this | |
50 | value for validity before passing it on to the underlying OpenGL | |
51 | implementation. A value that is not accepted by the OpenGL | |
52 | implementation will lead to an OpenGL error. The benefit of not | |
53 | checking this value at the GLU level is that OpenGL extensions can add | |
54 | new internal texture formats without requiring a revision of the GLU | |
55 | implementation. Older implementations of GLU check this value and | |
56 | raise a GLU error if it is not 1, 2, 3, or 4 or one of the following | |

170 | <function>gluBuild2DMipmaps</function> builds a series of prefiltered two-dimensional texture maps of decreasing | |
171 | resolutions called a mipmap. This is used for the antialiasing of | |
172 | texture-mapped primitives. | |
173 | </para> | |
174 | <para> | |
175 | A return value of zero indicates success, otherwise a GLU error code is | |
176 | returned (see <citerefentry><refentrytitle>gluErrorString</refentrytitle></citerefentry>). | |
177 | </para> | |
178 | <para> | |
179 | Initially, the <parameter>width</parameter> and <parameter>height</parameter> of <parameter>data</parameter> are checked to see if they | |
180 | are a power of 2. If not, a copy of <parameter>data</parameter> (not <parameter>data</parameter>), is scaled up | |
181 | or down to the nearest power of 2. This copy will be used for subsequent | |
182 | mipmapping operations described below. (If <parameter>width</parameter> or <parameter>height</parameter> is exactly | |
183 | between powers of 2, then the copy of <parameter>data</parameter> will scale upwards.) For | |
184 | example, if <parameter>width</parameter> is 57 and <parameter>height</parameter> is 23, then a copy of <parameter>data</parameter> will | |
185 | scale up to 64 in <parameter>width</parameter> and down to 16 in depth, before mipmapping takes | |
186 | place. | |
187 | </para> | |
188 | <para> | |
189 | Then, proxy textures (see <citerefentry><refentrytitle>glTexImage2D</refentrytitle></citerefentry>) are used to determine if | |
190 | the implementation can fit the requested texture. If not, both dimensions | |
191 | are continually halved until it fits. (If the OpenGL version is \(<= 1.0, | |
192 | both maximum texture dimensions are clamped to the value returned | |
193 | by <citerefentry><refentrytitle>glGetIntegerv</refentrytitle></citerefentry> with the argument <constant>GLU_MAX_TEXTURE_SIZE</constant>.) | |
194 | </para> | |
195 | <para> | |
196 | Next, a series of mipmap levels is built by decimating a copy of <parameter>data</parameter> | |
197 | in half along both dimensions until size | |

206 | is reached. At | |
207 | each level, | |
208 | each texel in the halved mipmap level is an average of the corresponding | |
209 | four texels in the larger mipmap level. (In the case of rectangular | |
210 | images, the decimation will ultimately reach an | |

229 | </para> | |
230 | <para> | |
231 | <citerefentry><refentrytitle>glTexImage2D</refentrytitle></citerefentry> is called to load each of these mipmap levels. | |
232 | Level 0 is a copy of <parameter>data</parameter>. The highest level is | |

327 | Note that there is no direct way of querying the maximum level. This can | |
328 | be derived indirectly via <citerefentry><refentrytitle>glGetTexLevelParameter</refentrytitle></citerefentry>. First, query | |
329 | for the width and height actually used at level 0. (The width and | |
330 | height may not be equal to <parameter>width</parameter> and <parameter>height</parameter> respectively since proxy | |
