glGetTexParameter returns in params the value or values of the texture parameter specified as pname. target defines the target texture, either GL_TEXTURE_1D, GL_TEXTURE_2D, or GL_TEXTURE_3D to specify one-, two-, or three-dimensional texturing. pname accepts the same symbols as glTexParameter, with the same interpretations:GL_TEXTURE_MAG_FILTER
Returns the single-valued texture magnification filter, a symbolic constant. The initial value is GL_LINEAR.
GL_TEXTURE_MIN_FILTER
Returns the single-valued texture minification filter, a symbolic constant. The initial value is GL_NEAREST_MIPMAP_LINEAR.
GL_TEXTURE_MIN_LOD
Returns the single-valued texture minimum level-of-detail value. The initial value is $-1000$.
GL_TEXTURE_MAX_LOD
Returns the single-valued texture maximum level-of-detail value. The initial value is 1000.
GL_TEXTURE_BASE_LEVEL
Returns the single-valued base texture mipmap level. The initial value is 0.
GL_TEXTURE_MAX_LEVEL
Returns the single-valued maximum texture mipmap array level. The initial value is 1000.
GL_TEXTURE_WRAP_S
Returns the single-valued wrapping function for texture coordinate $s$, a symbolic constant. The initial value is GL_REPEAT.
GL_TEXTURE_WRAP_T
Returns the single-valued wrapping function for texture coordinate $t$, a symbolic constant. The initial value is GL_REPEAT.
GL_TEXTURE_WRAP_R
Returns the single-valued wrapping function for texture coordinate $r$, a symbolic constant. The initial value is GL_REPEAT.
GL_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).
GL_TEXTURE_PRIORITY
Returns the residence priority of the target texture (or the named texture bound to it). The initial value is 1. See glPrioritizeTextures.
GL_TEXTURE_RESIDENT
Returns the residence status of the target texture. If the value returned in params is GL_TRUE, the texture is resident in texture memory. See glAreTexturesResident.
