This is used for the antialiasing of -texture mapped primitives. -.P -A return value of zero indicates success, otherwise a GLU error code is -returned (see _cmnd(ErrorString)). -.P -A series of mipmap levels from _param7 to _param8 is built by decimating -_param9 in half -until size $1 ~times~ 1$ is reached. At each level, each texel in the -halved mipmap level is an average of the corresponding two texels in the larger -mipmap level. -_glcmnd(TexImage1D) is called to load these mipmap levels from _param7 -to _param8. If _param8 is larger than the highest mipmap level for the -texture of the specified size, then a GLU error code is returned (see -_cmnd(ErrorString)) and nothing is loaded. -.P -For example, if _param6 is 2 and _param3 is 16, the -following levels are possible: $16 ~times~ 1$, $8 ~times~ 1$, $4 ~times~ 1$, -$2 ~times~ 1$, $1 ~times~ 1$. These correspond -to levels 2 through 6 respectively. -If _param7 is 3 and _param8 is 5, then only mipmap levels $8 ~times~ 1$, -$4 ~times~ 1$ and $2 ~times~ 1$ are -loaded. However, if _param8 is 7 then an error is returned and nothing is -loaded since _param8 is larger than the highest mipmap level which is, in -this case, 6. -.P -The highest mipmap level can be derived from the formula -${log sub 2} (_param3^{2 sup _param6})$. -.P -See the _glcmnd(TexImage1D) reference page for a description of the -acceptable values for _param5 parameter. See the _glcmnd(DrawPixels) -reference page for a description of the acceptable values -for _param6 parameter. -.bp -.SH NOTES -_cmnd is only available if the GLU version is 1.3 or greater. -.P -Formats _const(BGR), and _const(BGRA), and types -_const(UNSIGNED_BYTE_3_3_2), -_const(UNSIGNED_BYTE_2_3_3_REV), -_const(UNSIGNED_SHORT_5_6_5), -_const(UNSIGNED_SHORT_5_6_5_REV), -_const(UNSIGNED_SHORT_4_4_4_4), -_const(UNSIGNED_SHORT_4_4_4_4_REV), -_const(UNSIGNED_SHORT_5_5_5_1), -_const(UNSIGNED_SHORT_1_5_5_5_REV), -_const(UNSIGNED_INT_8_8_8_8), -_const(UNSIGNED_INT_8_8_8_8_REV), -_const(UNSIGNED_INT_10_10_10_2), and -_const(UNSIGNED_INT_2_10_10_10_REV) are only available if the GL version -is 1.2 or greater. -.SH ERRORS -_gluconst(INVALID_VALUE) is returned if _param6 > _param7, _param7 < 0, -_param8 < _param7 or _param8 is > the highest mipmap level for _param9. -.P -_gluconst(INVALID_VALUE) is returned if _param3 is < 1. -.P -_gluconst(INVALID_ENUM) is returned if _param2, _param4, or _param5 are not -legal. -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_BYTE_3_3_2) or _const(UNSIGNED_BYTE_2_3_3_REV) -and _param4 is not _const(RGB). -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_SHORT_5_6_5) or _const(UNSIGNED_SHORT_5_6_5_REV) -and _param4 is not _const(RGB). -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_SHORT_4_4_4_4) or _const(UNSIGNED_SHORT_4_4_4_4_REV) -and _param4 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_SHORT_5_5_5_1) or _const(UNSIGNED_SHORT_1_5_5_5_REV) -and _param4 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_INT_8_8_8_8) or _const(UNSIGNED_INT_8_8_8_8_REV) -and _param4 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param5 is _const(UNSIGNED_INT_10_10_10_2) or _const(UNSIGNED_INT_2_10_10_10_REV) -and _param4 is neither _const(RGBA) nor _const(BGRA). -.SH SEE ALSO -_glcmnd(DrawPixels), _glcmnd(TexImage1D), _glcmnd(TexImage2D), -_glcmnd(TexImage3D), -_cmnd(Build1DMipmaps), _cmnd(Build2DMipmaps), _cmnd(Build3DMipmaps), -_cmnd(ErrorString), -_glcmnd(GetTexImage), -_glcmnd(GetTexLevelParameter), -_cmnd(Build2DMipmapLevels), _cmnd(Build3DMipmapLevels) |
