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 -Initially, the _param3 of _param6 is checked to see if it is -a power of 2. If not, a copy of _param6 is scaled up or down to the -nearest power of 2. (If _param3 is exactly between powers of 2, then -the copy of _param6 will scale upwards.) This copy will be used for -subsequent mipmapping operations described below. -For example, if _param3 is 57 then a copy of _param6 -will scale up to 64 before mipmapping -takes place. -.P -Then, proxy textures (see _glcmnd(TexImage1D)) are used to determine if -the implementation can fit the requested texture. If not, _param3 is -continually halved until it fits. -.P -Next, a series of mipmap levels is built by decimating a copy of -_param6 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. -.P -_glcmnd(TexImage1D) is called to load each of these mipmap levels. -Level 0 is a copy of _param6. -The highest level is ${log sub 2}(_param3)$. -For example, if _param3 is 64 and the implementation can store a texture of -this size, the following mipmap levels are -built: $64 ~times~ 1$, $32 ~times~ 1$, $16 ~times~ 1$, $8 ~times~ 1$, -$4 ~times~ 1$, $2 ~times~ 1$ and $1 ~times~ 1$. These correspond to -levels 0 through 6, respectively. -.P -See the _glcmnd(TexImage1D) reference page for a description of the -acceptable values for the _param5 parameter. See the _glcmnd(DrawPixels) -reference page for a description of the acceptable values -for the _param6 parameter. -.SH NOTES -Note that there is no direct way of querying the maximum level. This can -be derived indirectly via _glcmnd(GetTexLevelParameter). First, query -for the -width actually used at level 0. -(The width may not be equal to _param3 since -proxy textures might have scaled it to fit the implementation.) -Then the maximum -level can be derived from the formula ${log sub 2}(_param3)$. -.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, and if the GLU version is 1.3 or greater. -.SH ERRORS -_gluconst(INVALID_VALUE) is returned if _param3 is < 1. -.P -_gluconst(INVALID_ENUM) is returned if _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(Build2DMipmaps), -_cmnd(Build3DMipmaps), -_cmnd(ErrorString), -_glcmnd(GetTexImage), -_glcmnd(GetTexLevelParameter), -_cmnd(Build1DMipmapLevels), -_cmnd(Build2DMipmapLevels), -_cmnd(Build3DMipmapLevels) |
