Member Typedef Documentation

◆ Rebind

using Rebind = Vec2<U, STRIDE>

◆ VectorStrideType

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

◆ ValueType

using ValueType = T

◆ ValueTypeParam

using ValueTypeParam = typename ByValueParam<T>::type

◆ Unstrided

using Unstrided = Vec2<T, 1>

◆ BoolType

using BoolType = decltype(T() == T())

The type returned by comparisons. If the template argument for T is a SIMD type, this will be a SIMD type, too, which contains the per-element results.

Constructor & Destructor Documentation

◆ Vec2() [1/8]

constexpr Vec2 ( )

constexpr

Initializes all vector components with 0.0.

◆ Vec2() [2/8]

constexpr Vec2 ( ValueTypeParam in )

explicitconstexpr

Initializes all vector components with a scalar.

◆ Vec2() [3/8]

constexpr Vec2	(	ValueTypeParam	ix,
		ValueTypeParam	iy
	)

explicitconstexpr

Initializes all vector components individually.

◆ Vec2() [4/8]

constexpr Vec2 ( const Vec2< T2, S2 > & v )

explicitconstexpr

Initializes components from another 2d vector.

◆ Vec2() [5/8]

constexpr Vec2 ( const Vec2< T, S2 > & v )

constexpr

Initializes components from another 2d vector.

◆ Vec2() [6/8]

constexpr Vec2 ( const Vec3< T2, S2 > & v )

explicitconstexpr

Initializes components from a 3d vector. The z-component of v is ignored.

◆ Vec2() [7/8]

constexpr Vec2 ( ENUM_DONT_INITIALIZE v )

explicitconstexpr

Skips initialization of vector (for better speed)

◆ Vec2() [8/8]

constexpr MAXON_IMPLICIT Vec2 ( const typename std::conditional< STRIDE==1, DummyParamType, Vec2< 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.
