Member Typedef Documentation

◆ Rebind

using Rebind = Vec3<U, STRIDE>

◆ VectorStrideType

using VectorStrideType = std::integral_constant<Int, STRIDE>

◆ ValueType

using ValueType = T

using ValueTypeParam = typename ByValueParam<T>::type

◆ Unstrided

Constructor & Destructor Documentation

explicitconstexpr

Initializes all vector components with a scalar.

◆ Vec3() [3/11]

constexpr Vec3	(	ValueTypeParam	ix,
		ValueTypeParam	iy,
		ValueTypeParam	iz
	)

explicitconstexpr

Initializes all vector components individually.

◆ Vec3() [4/11]

constexpr Vec3 ( const Vec3< T2, S2 > & v )

explicitconstexpr

Initializes components from another 3d vector.

◆ Vec3() [5/11]

constexpr Vec3 ( const Col3< T2, S2 > & v )

explicitconstexpr

Initializes components from another 3d vector.

◆ Vec3() [6/11]

constexpr Vec3 ( const Vec3< T, S2 > & v )

constexpr

Initializes components from another 3d vector.

◆ Vec3() [7/11]

constexpr Vec3	(	const Vec2< T2, S2, SPACE2 > &	v,
		T	vz = `T()`
	)

explicitconstexpr

Initializes components from a 2d vector. The z-component is set to 0.0 unless an extra parameter is passed.

◆ Vec3() [8/11]

constexpr Vec3 ( const Vec4< T2, S2 > & v )

explicitconstexpr

Initializes components from a 4d vector. The w-component is omitted.

◆ Vec3() [9/11]

constexpr Vec3 ( const Col4< T2, S2 > & v )

explicitconstexpr

Initializes components from a 4d vector. The w-component is omitted.

◆ Vec3() [10/11]

constexpr Vec3 ( ENUM_DONT_INITIALIZE v )

explicitconstexpr

◆ Vec3() [11/11]

constexpr MAXON_IMPLICIT Vec3 ( const typename std::conditional< STRIDE==1, DummyParamType, Vec3< T, STRIDE > >::type & src )

constexpr

When STRIDE is not 1, we have to provide copy constructor and operator because the default ones would also copy the padding. When STRIDE is 1, we want to avoid to declare them (because then the type wouldn't be trivially copyable any longer), so we use DummyParamType for the parameter in that case.
