The initial value is _const(LINEAR). +.TP +_const(TEXTURE_MIN_FILTER) +Returns the single-valued texture minification filter, +a symbolic constant. The initial value is _const(NEAREST_MIPMAP_LINEAR). +.TP +_const(TEXTURE_MIN_LOD) +Returns the single-valued texture minimum level-of-detail value. The +initial value is $-1000$. +.TP +_const(TEXTURE_MAX_LOD) +Returns the single-valued texture maximum level-of-detail value. The +initial value is 1000. +.TP +_const(TEXTURE_BASE_LEVEL) +Returns the single-valued base texture mipmap level. The initial value is 0. +.TP +_const(TEXTURE_MAX_LEVEL) +Returns the single-valued maximum texture mipmap array level. The initial +value is 1000. +.TP +_const(TEXTURE_WRAP_S) +Returns the single-valued wrapping function for texture coordinate $s$, +a symbolic constant. The initial value is _const(REPEAT). +.TP +_const(TEXTURE_WRAP_T) +Returns the single-valued wrapping function for texture coordinate $t$, +a symbolic constant. The initial value is _const(REPEAT). +.TP +_const(TEXTURE_WRAP_R) +Returns the single-valued wrapping function for texture coordinate $r$, +a symbolic constant. The initial value is _const(REPEAT). +.BP +.TP +_const(TEXTURE_BORDER_COLOR) +Returns four integer or floating-point numbers that comprise the RGBA color +of the texture border. +Floating-point values are returned in the range [0, 1]. +Integer values are returned as a linear mapping of the internal floating-point +representation such that 1.0 maps to the most positive representable +integer and \-1.0 maps to the most negative representable +integer. The initial value is (0, 0, 0, 0). +.TP +_const(TEXTURE_PRIORITY) +Returns the residence priority of the target texture (or the named +texture bound to it). The initial value is 1. +See _cmnd(PrioritizeTextures). +.TP +_const(TEXTURE_RESIDENT) +Returns the residence status of the target texture. +If the value returned in _param3 is _const(TRUE), the texture is +resident in texture memory. +See _cmnd(AreTexturesResident). +.SH NOTES +_const(TEXTURE_PRIORITY) and _const(TEXTURE_RESIDENT) are +available only if the GL version is 1.1 or greater. +.P +_const(TEXTURE_3D), +_const(TEXTURE_MIN_LOD), _const(TEXTURE_MAX_LOD), _const(TEXTURE_BASE_LEVEL), +_const(TEXTURE_MAX_LEVEL), and _const(TEXTURE_WRAP_R) are available only +if the GL version is 1.2 or greater. +.P +If an error is generated, +no change is made to the contents of _param3. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 or _param2 is not an +accepted value. +.P +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). +.SH SEE ALSO +_cmnd(AreTexturesResident), +_cmnd(PrioritizeTextures), +_cmnd(TexParameter) |
