NAME¶
glGetSamplerParameter - return sampler parameter valuesC SPECIFICATION¶
void
glGetSamplerParameterfv(GLuint sampler,
GLenum pname,
GLfloat * params);
void
glGetSamplerParameteriv(GLuint sampler,
GLenum pname,
GLint * params);
PARAMETERS¶
samplerSpecifies name of the sampler object from
which to retrieve parameters.
pname
Specifies the symbolic name of a sampler
parameter. GL_TEXTURE_MAG_FILTER, GL_TEXTURE_MIN_FILTER,
GL_TEXTURE_MIN_LOD, GL_TEXTURE_MAX_LOD,
GL_TEXTURE_LOD_BIAS, GL_TEXTURE_WRAP_S,
GL_TEXTURE_WRAP_T, GL_TEXTURE_WRAP_R,
GL_TEXTURE_BORDER_COLOR, GL_TEXTURE_COMPARE_MODE, and
GL_TEXTURE_COMPARE_FUNC are accepted.
params
Returns the sampler parameters.
DESCRIPTION¶
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_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_COMPARE_MODE
Returns a single-valued texture comparison
mode, a symbolic constant. The initial value is GL_NONE. See
glSamplerParameter().
GL_TEXTURE_COMPARE_FUNC
Returns a single-valued texture comparison
function, a symbolic constant. The initial value is GL_LEQUAL. See
glSamplerParameter().
