Detailed Description

Provide functions to increase the compatibility with Cg and HLSL languages.

Include <glm/gtx/common.hpp> to use the features of this extension.

Function Documentation

closeBounded()

template<length_t L, typename T , qualifier Q>

GLM_FUNC_DECL vec< L, bool, Q > glm::closeBounded	(	vec< L, T, Q > const &	Value,
		vec< L, T, Q > const &	Min,
		vec< L, T, Q > const &	Max )

Returns whether vector components values are within an interval. A closed interval includes its endpoints, and is denoted with square brackets.

Template Parameters

L	Integer between 1 and 4 included that qualify the dimension of the vector
T	Floating-point or integer scalar types
Q	Value from qualifier enum

fmod()

template<length_t L, typename T , qualifier Q>

GLM_FUNC_DECL vec< L, T, Q > glm::fmod

(

vec< L, T, Q > const &

v

)

Similar to 'mod' but with a different rounding and integer support. Returns 'x - y * trunc(x/y)' instead of 'x - y * floor(x/y)'

isdenormal()

template<typename genType >

GLM_FUNC_DECL genType::bool_type glm::isdenormal

(

genType const &

x

)

Returns true if x is a denormalized number Numbers whose absolute value is too small to be represented in the normal format are represented in an alternate, denormalized format. This format is less precise but can represent values closer to zero.

Template Parameters

genType

Floating-point scalar or vector types.

openBounded()

template<length_t L, typename T , qualifier Q>

GLM_FUNC_DECL vec< L, bool, Q > glm::openBounded	(	vec< L, T, Q > const &	Value,
		vec< L, T, Q > const &	Min,
		vec< L, T, Q > const &	Max )

Returns whether vector components values are within an interval. A open interval excludes its endpoints, and is denoted with square brackets.

Template Parameters

L	Integer between 1 and 4 included that qualify the dimension of the vector
T	Floating-point or integer scalar types
Q	Value from qualifier enum
