Vec3 class
3-dimensional vector @example final v = new Vec3(1, 2, 3) console.log('x=' + v.x) // x=1
Properties
Methods
-
addScaledVector(
double scalar, Vec3 vector, [Vec3? target]) → Vec3 - Scale a vector and add it to this vector. Save the result in "target". (target = this + vector * scalar) @param target The vector to save the result in.
-
almostEquals(
Vec3 vector, [double? precision]) → bool - Check if a vector equals is almost equal to another one.
-
almostZero(
[double precision = 1e-6]) → bool - Check if a vector is almost zero
-
clone(
) → Vec3 - Clone the vector
-
copy(
Vec3 vector) → Vec3 - Copies value of source to this vector.
-
cross(
Vec3 vector, [Vec3? target]) → Vec3 - Vector cross product @param target Optional target to save in.
-
crossmat(
) → Mat3 - Get the cross product matrix a_cross from a vector, such that a x b = a_cross * b = c
-
crossVectors(
Vec3 a, Vec3 b) → Vec3 -
distanceSquared(
Vec3 p) → double - Get squared distance from this point to another point
-
distanceTo(
Vec3 p) → double - Get distance from this point to another point
-
dot(
Vec3 vector) → double - Calculate dot product @param vector
-
inverse(
) → Vec3 - Vector cross product @param target Optional target to save in.
-
isAntiparallelTo(
Vec3 vector, [double? precision]) → bool - Check if the vector is anti-parallel to another vector. @param precision Set to zero for exact comparisons
-
isZero(
) → bool -
length(
) → double - Get the length of the vector
-
lengthSquared(
) → double - Get the squared length of the vector.
-
lerp(
Vec3 vector, double t, Vec3 target) → void - Do a linear interpolation between two vectors @param t A number between 0 and 1. 0 will make this function return u, and 1 will make it return v. Numbers in between will generate a vector in between them.
-
negate(
Vec3 target) → Vec3 - Make the vector point in the opposite direction. @param target Optional target to save in
-
normalize(
) → double - Normalize the vector. Note that this changes the values in the vector. @return Returns the norm of the vector
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
scale(
double scalar, [Vec3? target]) → Vec3 - Multiply all the components of the vector with a scalar. @param target The vector to save the result in.
-
set(
double x, double y, double z) → Vec3 - Set the vectors' 3 elements
-
setZero(
) → void - Set all components of the vector to zero.
-
subVectors(
Vec3 a, Vec3 b) → Vec3 -
sum(
) → int -
tangents(
Vec3 t1, Vec3 t2) → void - Compute two artificial tangents to the vector @param t1 Vector object to save the first tangent in @param t2 Vector object to save the second tangent in
-
toArray(
) → List< double> - Converts to an array
-
toQuant(
) → Quaternion -
toString(
) → String -
Converts to a more readable format
override
-
unit(
[Vec3? target]) → Vec3 - Get the version of this vector that is of length 1. @param target Optional target to save in @return Returns the unit vector
-
vadd(
Vec3 vector, [Vec3? target]) → Vec3 - Vector addition
-
vmul(
Vec3 vector, [Vec3? target]) → Vec3 - Multiply the vector with an other vector, component-wise. @param target The vector to save the result in.
-
vsub(
Vec3 vector, [Vec3? target]) → Vec3 - Vector subtraction @param target Optional target to save in.
