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 _param9 to _param10 is built by -decimating _param11 in half along both dimensions until size $1 ~times~ 1 -~times~ 1$ is reached. At each level, each texel in the halved mipmap -level is an average of the corresponding eight texels in the larger -mipmap level. (If exactly one of the dimensions is 1, four texels are -averaged. If exactly two of the dimensions are 1, two texels are -averaged.) _glcmnd(TexImage3D) is called to load these mipmap levels -from _param9 to _param10. If _param10 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 _param8 is 2 and _param3 is 16, _param4 is 8 and _param5 -is 4, the following levels are possible: $16 ~times~ 8 ~times~ 4$, $8 ~times~ -4 ~times~ 2$, $4 ~times~ 2 ~times~ 1$, $2 ~times~ 1 ~times~ 1$, -$1 ~times~ 1 ~times~ 1$. -These correspond to levels 2 through 6 respectively. If _param9 is -3 and _param10 is 5, then only mipmap levels $8 ~times~ 4 ~times~ 2$, $4 -~times~ 2 ~times~ 1$ and $2 ~times~ 1 ~times~ 1$ are loaded. However, if -_param10 is 7 then an error is returned and nothing is loaded, since -_param10 is larger than the highest mipmap level which is, in this case, -6. -.P -The highest mipmap level can be derived from the formula -${log sub 2} ( max (_eqnparam3,_eqnparam4,_eqnparam5)^{2 sup _eqnparam8})$. -.P -See the _glcmnd(TexImage1D) reference page for a description of the -acceptable values for _param6 parameter. See the _glcmnd(DrawPixels) -reference page for a description of the acceptable values -for _param7 parameter. -.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 _param8 > _param9, _param9 < 0, -_param10 < _param9 or _param10 is > the highest mipmap level for _param11. -.P -_gluconst(INVALID_VALUE) is returned if _param3, _param4, or _param5 is < 1. -.P -_gluconst(INVALID_ENUM) is returned if _param2, _param6, or _param7 is not -legal. -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_BYTE_3_3_2) or _const(UNSIGNED_BYTE_2_3_3_REV) -and _param6 is not _const(RGB). -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_SHORT_5_6_5) or _const(UNSIGNED_SHORT_5_6_5_REV) -and _param6 is not _const(RGB). -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_SHORT_4_4_4_4) or _const(UNSIGNED_SHORT_4_4_4_4_REV) -and _param6 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_SHORT_5_5_5_1) or _const(UNSIGNED_SHORT_1_5_5_5_REV) -and _param6 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_INT_8_8_8_8) or _const(UNSIGNED_INT_8_8_8_8_REV) -and _param6 is neither _const(RGBA) nor _const(BGRA). -.P -_gluconst(INVALID_OPERATION) is returned if _param7 is _const(UNSIGNED_INT_10_10_10_2) or _const(UNSIGNED_INT_2_10_10_10_REV) -and _param6 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(Build1DMipmapLevels), -_cmnd(Build2DMipmapLevels) |
