enum comp |
T |

Definition at line 15 of file _swizzle.hpp.
GLM_FUNC_QUALIFIER bool glm::all | ( | vecType< bool > const & | v | ) |
Returns true if all components of x are true.
Definition at line 177 of file func_vector_relational.hpp.
GLM_FUNC_QUALIFIER bool glm::any | ( | vecType< bool > const & | v | ) |
Returns true if any component of x is true.
Definition at line 161 of file func_vector_relational.hpp.
genType glm::ceil | ( | genType const & | x | ) |
Returns a value equal to the nearest integer that is greater than or equal to x.
genType glm::clamp | ( | genType const & | x, |
genType const & | minVal, | ||
genType const & | maxVal | ||
) |
Returns min(max(x, minVal), maxVal) for each component in x.
using the floating-point values minVal and maxVal.

GLM_FUNC_QUALIFIER vecType<T>::bool_type glm::equal | ( | vecType< T > const & | x, |
vecType< T > const & | y | ||
) |
Returns the component-wise comparison of result x == y.
Definition at line 122 of file func_vector_relational.hpp.
genIType glm::floatBitsToInt | ( | genType const & | value | ) |
Returns a signed integer value representing the encoding of a floating-point value.
The floatingpoint value's bit-level representation is preserved.
genUType glm::floatBitsToUint | ( | genType const & | value | ) |
Returns a unsigned integer value representing the encoding of a floating-point value.
The floatingpoint value's bit-level representation is preserved.
genType glm::floor | ( | genType const & | x | ) |
Returns a value equal to the nearest integer that is less then or equal to x.
genType glm::fma | ( | genType const & | a, |
genType const & | b, | ||
genType const & | c | ||
) |
Computes and returns a * b + c.
genType glm::fract | ( | genType const & | x | ) |
Return x - floor(x).
genType glm::frexp | ( | genType const & | x, |
genIType & | exp | ||
) |
Splits x into a floating-point significand in the range [0.5, 1.0) and an integral exponent of two, such that: x = significand * exp(2, exponent)
The significand is returned by the function and the exponent is returned in the parameter exp. For a floating-point value of zero, the significant and exponent are both zero. For a floating-point value that is an infinity or is not a number, the results are undefined.
GLM_FUNC_QUALIFIER vecType<T>::bool_type glm::greaterThan | ( | vecType< T > const & | x, |
vecType< T > const & | y | ||
) |
Returns the component-wise comparison of result x > y.
Definition at line 78 of file func_vector_relational.hpp.
GLM_FUNC_QUALIFIER vecType<T>::bool_type glm::greaterThanEqual | ( | vecType< T > const & | x, |
vecType< T > const & | y | ||
) |
Returns the component-wise comparison of result x >= y.
Definition at line 100 of file func_vector_relational.hpp.
genType glm::intBitsToFloat | ( | genIType const & | value | ) |
Returns a floating-point value corresponding to a signed integer encoding of a floating-point value.
If an inf or NaN is passed in, it will not signal, and the resulting floating point value is unspecified. Otherwise, the bit-level representation is preserved.
genType::bool_type glm::isinf | ( | genType const & | x | ) |
Returns true if x holds a positive infinity or negative infinity representation in the underlying implementation's set of floating point representations.
Returns false otherwise, including for implementations with no infinity representations.
genType::bool_type glm::isnan | ( | genType const & | x | ) |
Returns true if x holds a NaN (not a number) representation in the underlying implementation's set of floating point representations.
Returns false otherwise, including for implementations with no NaN representations.
genType glm::ldexp | ( | genType const & | x, |
genIType const & | exp | ||
) |
Builds a floating-point number from x and the corresponding integral exponent of two in exp, returning: significand * exp(2, exponent)
If this product is too large to be represented in the floating-point type, the result is undefined.
genType glm::max | ( | genType const & | x, |
genType const & | y | ||
) |
Returns y if x < y; otherwise, it returns x.
genType glm::min | ( | genType const & | x, |
genType const & | y | ||
) |
Returns y if y < x; otherwise, it returns x.
genTypeT glm::mix | ( | genTypeT const & | x, |
genTypeT const & | y, | ||
genTypeU const & | a | ||
) |
[in] | x | Floating point scalar or vector. |
[in] | y | Floating point scalar or vector. |
[in] | a | Floating point or boolean scalar or vector. |

genType glm::mod | ( | genType const & | x, |
typename genType::value_type const & | y | ||
) |
Modulus.
Returns x - y * floor(x / y) for each component in x using the floating point value y.
genType glm::mod | ( | genType const & | x, |
genType const & | y | ||
) |
Modulus.
Returns x - y * floor(x / y) for each component in x using the floating point value y.
genType glm::modf | ( | genType const & | x, |
genType & | i | ||
) |
Returns the fractional part of x and sets i to the integer part (as a whole number floating point value).
Both the return value and the output parameter will have the same sign as x.
GLM_FUNC_QUALIFIER vecType<bool> glm::not_ | ( | vecType< bool > const & | v | ) |
Returns the component-wise logical complement of x.
/!\ Because of language incompatibilities between C++ and GLSL, GLM defines the function not but not_ instead.
Definition at line 194 of file func_vector_relational.hpp.
GLM_FUNC_QUALIFIER vecType<T>::bool_type glm::notEqual | ( | vecType< T > const & | x, |
vecType< T > const & | y | ||
) |
Returns the component-wise comparison of result x != y.
Definition at line 142 of file func_vector_relational.hpp.
genType glm::round | ( | genType const & | x | ) |
Returns a value equal to the nearest integer to x.
The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest. This includes the possibility that round(x) returns the same value as roundEven(x) for all values of x.
genType glm::roundEven | ( | genType const & | x | ) |
Returns a value equal to the nearest integer to x.
A fractional part of 0.5 will round toward the nearest even integer. (Both 3.5 and 4.5 for x will return 4.0.)
genFIType glm::sign | ( | genFIType const & | x | ) |
Returns 1.0 if x > 0, 0.0 if x == 0, or -1.0 if x < 0.
genType glm::smoothstep | ( | genType const & | edge0, |
genType const & | edge1, | ||
genType const & | x | ||
) |
Returns 0.0 if x <= edge0 and 1.0 if x >= edge1 and performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1.
This is useful in cases where you would want a threshold function with a smooth transition. This is equivalent to: genType t; t = clamp ((x – edge0) / (edge1 – edge0), 0, 1); return t * t * (3 – 2 * t); Results are undefined if edge0 >= edge1.
genType glm::step | ( | genType const & | edge, |
genType const & | x | ||
) |
Returns 0.0 if x < edge, otherwise it returns 1.0.
genType glm::trunc | ( | genType const & | x | ) |
Returns a value equal to the nearest integer to x whose absolute value is not larger than the absolute value of x.
genType glm::uintBitsToFloat | ( | genUType const & | value | ) |
Returns a floating-point value corresponding to a unsigned integer encoding of a floating-point value.
If an inf or NaN is passed in, it will not signal, and the resulting floating point value is unspecified. Otherwise, the bit-level representation is preserved.
