See +_cmnd(TexImage3D) for specific details. +.SH ERRORS +_const(INVALID_ENUM) is generated if __target is not _const(TEXTURE_3D). +.P +_const(INVALID_OPERATION) is generated if the texture array has not +been defined by a previous _cmnd(TexImage3D) operation. +.P +_const(INVALID_VALUE) is generated if __level is less than 0. +.P +_const(INVALID_VALUE) may be generated if __level is greater +than $log sub 2$\f2max\fP, +where \f2max\fP is the returned value of _const(MAX_TEXTURE_SIZE). +.P +_const(INVALID_VALUE) is generated if $__eqnxoffset ~<~ ~-b$, +$(__eqnxoffset ~+~ __eqnwidth) ~>~ (w~-~b)$, +$__eqnyoffset ~<~ ~-b$, or $(__eqnyoffset ~+~ __eqnheight) ~>~ (h~-~b)$, +or $__eqnzoffset ~<~ ~-b$, or $(__eqnzoffset ~+~ __eqndepth) ~>~ (d~-~b)$, +where $w$ is the _const(TEXTURE_WIDTH), +$h$ is the _const(TEXTURE_HEIGHT), $d$ is the _const(TEXTURE_DEPTH) +and $b$ is the border width of the texture image being modified. +Note that $w$, $h$, and $d$ include twice the border width. +.P +_const(INVALID_VALUE) is generated if __width, __height, or __depth +is less than 0. +.P +_const(INVALID_ENUM) is generated if __format is not an accepted +format constant. +.P +_const(INVALID_ENUM) is generated if __type is not a type constant. +.P +_const(INVALID_ENUM) is generated if __type is _const(BITMAP) and +__format is not _const(COLOR_INDEX). +.P +_const(INVALID_OPERATION) is generated if _cmnd is executed +between the execution of _cmnd(Begin) and the corresponding +execution of _cmnd(End). +.P +_const(INVALID_OPERATION) is generated if __type is one of +_const(UNSIGNED_BYTE_3_3_2), +_const(UNSIGNED_BYTE_2_3_3_REV), +_const(UNSIGNED_SHORT_5_6_5), or +_const(UNSIGNED_SHORT_5_6_5_REV) +and __format is not _const(RGB). +.P +_const(INVALID_OPERATION) is generated if __type is one of +_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), or +_const(UNSIGNED_INT_2_10_10_10_REV) +and __format is neither _const(RGBA) nor _const(BGRA). +.SH ASSOCIATED GETS +_cmnd(GetTexImage) +.br +_cmnd(IsEnabled) with argument _const(TEXTURE_3D) +.SH SEE ALSO +_cmnd(ActiveTextureARB), +_cmnd(CopyTexImage1D), +_cmnd(CopyTexImage2D), +_cmnd(CopyTexSubImage1D), +_cmnd(CopyTexSubImage2D), +_cmnd(CopyTexSubImage3D), +_cmnd(DrawPixels), +_cmnd(PixelStore), +_cmnd(PixelTransfer), +_cmnd(TexEnv), +_cmnd(TexGen), +_cmnd(TexImage1D), +_cmnd(TexImage2D), +_cmnd(TexImage3D), +_cmnd(TexSubImage1D), +_cmnd(TexSubImage2D), +_cmnd(TexParameter) + |
