Vector2d Class
| Name | Description | |
|---|---|---|
|
Vector2d() | Creates a zero length vector |
|
|
Vector2d(Point2d, Point2d) | Creates a vector that represents the translation from a point to another. |
|
|
Vector2d(Point2d) | Creates a vector taking x,y from the point |
|
|
Vector2d(Vector2d) | Copy constructor. |
|
|
Vector2d(double, double) | Creates a vector with x and y as data. |
| Name | Description | |
|---|---|---|
|
Angle | Gets the angle of the vector. |
|
|
LeftNormal | Gets the normal on the left side of this vector as a new vector that has the same length as this one. This means: Vector2d(1,0).LeftNormal equals Vector2d(0,1) |
|
|
Length | Gets or sets the length of the vector. |
|
|
RightNormal | Gets the normal on the right side of this vector as a new vector that has the same length as this one. This means: Vector2d(1,0).LeftNormal equals Vector2d(0,-1) |
|
|
SquaredLength | Gets the The squared length of the vector. This is faster than than getting it's actual length. |
|
XAxis | |
|
|
YAxis |
| Name | Description | |

|
|
AngleCCW(Vector2d) | Computes the counter clockwise angle from this vector to another. |
|
|
AngleCW(Vector2d) | Computes the clockwise angle from this vector to another. |
|
|
CreateFromAngle(double) | Creates a unit vector with a given angle. |
|
|
CreateFromAngleAndLength(double, double) | Creates a vector with a given angle and length. |
|
|
Cross(Vector2d) | |
|
|
DifferentialAngle(Vector2d) | Computes the angular difference from this vector to another in the range -PI to +PI. |
|
|
DirectionalWith(Vector2d, double) | Checks if the vector has the same direction as another with a given tolerance. |
|
|
DotProduct(Vector2d) | Computes the dot product between this vector and another. If the vectors are normalized this is the same as cosine of the smallest angle between vectors. |
|
|
Equals(Vector2d, double) | Checks if this vector is about the same as another with a given tolerance. |
|
|
GetBisector(Vector2d) | |
|
|
Normalize() | Normalizes the vector in-place, which means making its length 1.0 maintaining its angle. If the vectors length is 0.0 an exception is thrown. |
|
|
ParallelWith(Vector2d, double) | Checks if the vector is parallel with another with a given tolerance. |
|
|
PerpendicularDotProduct(Vector2d) | Computes the dot product of the vector perpendicular with this one and another. If the vectors are normalized this is the same as sine of the smallest angle between vectors. |
|
|
Rotate(double) | |
|
|
Rotate270() | |
|
|
Rotate90() | |
|
|
SmallestAngle(Vector2d) | Returns the angle between this vector and another. Tha angle returned is always the one less then PI. |
|
|
ToPoint() | Create a point (x,y) from the vector components (x,y). |
|
|
ToString() | Creates a string representation of the vector suitable for debugging. |
|
|
Transform(Matrix2d) | Transforms the vector in-place with a matrix. When transforming a vector, the translation portion of the matrix is ignored, just scaling and rotation is considered. |
| Name | Description | |
|---|---|---|
|
Addition | Creates a new vector that is a sum of two others. |
|
|
Division | Divides the length of the vector with a factor (scales it) |
|
|
Multiply | Multiplies the length of the vector with a factor (scales it) |
|
|
Multiply | Multiplies the length of the vector with a factor (scales it) |
|
|
Subtraction | Subtracts a vector from another into a new vector. |
|
|
UnaryNegation | Computes the negation of a vector into a new vector. |
