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

200 | <function>gluBuild3DMipmapLevels</function> builds a subset of prefiltered three-dimensional texture maps of | |

205 | A return value of zero indicates success, otherwise a GLU error code is | |

209 | A series of mipmap levels from <parameter>base</parameter> to <parameter>max</parameter> is built by | |

221 | is reached. At each level, each texel in the halved mipmap | |
222 | level is an average of the corresponding eight texels in the larger | |
223 | mipmap level. (If exactly one of the dimensions is 1, four texels are | |
224 | averaged. If exactly two of the dimensions are 1, two texels are | |
225 | averaged.) <citerefentry><refentrytitle>glTexImage3D</refentrytitle></citerefentry> is called to load these mipmap levels | |
226 | from <parameter>base</parameter> to <parameter>max</parameter>. If <parameter>max</parameter> is larger than the highest mipmap | |
227 | level for the texture of the specified size, then a GLU error code is | |
228 | returned (see <citerefentry><refentrytitle>gluErrorString</refentrytitle></citerefentry>) and nothing is loaded. | |
