Detailed Description

Allow to perform bit operations on integer values.

<glm/gtc/integer.hpp> need to be included to use these functionalities.

Function Documentation

| GLM_FUNC_DECL vecType<int, P> glm::iround | ( | vecType< T, P > 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.

Parameters

| x | The values of the argument must be greater or equal to zero. |

Template Parameters

| T | floating point scalar types. | | vecType | vector types. |

See alsoGLSL round man page GLM_GTC_integer

| GLM_FUNC_DECL genIUType glm::log2 | ( | genIUType | x | ) | |

Returns the log2 of x for integer values.

Can be reliably using to compute mipmap count from the texture size.

| GLM_FUNC_DECL genIUType glm::mod | ( | genIUType | x, | | | | genIUType | y | | | ) | | |

Modulus.

Returns x % y for each component in x using the floating point value y.

Template Parameters

| genIUType | Integer-point scalar or vector types. |

| GLM_FUNC_DECL vecType< T, P > mod | ( | vecType< T, P > const & | x, | | | | T | y | | | ) | | |

Modulus.

Returns x % y for each component in x using the floating point value y.

Template Parameters

| T | Integer scalar types. | | vecType | vector types. |

| GLM_FUNC_DECL vecType< T, P > mod | ( | vecType< T, P > const & | x, | | | | vecType< T, P > const & | y | | | ) | | |

Modulus.

Returns x % y for each component in x using the floating point value y.

Template Parameters
