Vector 结构

初始化 Vector 类的一个新实例

Length Property - the length of this Vector

LengthSquared Property - the squared length of this Vector

X - float. Default value is 0.

Y - float. Default value is 0.

Add: Vector + Point

Add: Vector + Vector

AngleBetween - the angle between 2 vectors

CrossProduct - Returns the cross product: vector1.X*vector2.Y - vector1.Y*vector2.X

Determinant - Returns the determinant det(vector1, vector2)

Multiply: Vector / float

Equals - compares this Vector with the passed in object. In this equality float.NaN is equal to itself, unlike in numeric equality. Note that float values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail.

Compares two Vector instances for object equality. In this equality float.NaN is equal to itself, unlike in numeric equality. Note that float values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail.

Returns the HashCode for this Vector

Multiply: float * Vector

Multiply: Vector * Matrix

Multiply - Returns the dot product: vector1.X*vector2.X + vector1.Y*vector2.Y

Multiply: Vector * float

Negates the values of X and Y on this Vector

Normalize - Updates this Vector to maintain its direction, but to have a length of 1. This is equivalent to dividing this Vector by Length

Subtract: Vector - Vector

Creates a string representation of this object based on the current culture.

Creates a string representation of this object based on the IFormatProvider passed in. If the provider is null, the CurrentCulture is used.

Operator Vector + Point

Operator Vector + Vector

Operator Vector / float

Explicit conversion to Size. Note that since Size cannot contain negative values, the resulting size will contains the absolute values of X and Y

Explicit conversion to Point

Compares two Vector instances for exact inequality. Note that float values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail. Furthermore, using this equality operator, float.NaN is not equal to itself.

Operator float * Vector

Operator Vector * Matrix

Operator Vector * Vector, interpreted as their dot product

Operator Vector * float

Operator Vector - Vector

Operator -Vector (unary negation)
