vector2d QML Basic Type | Qt Quick 5.15.18 (original) (raw)

real dotProduct(vector2d other)

Returns the scalar real result of the dot product of this vector2d with the other vector2d

var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.dotProduct(b); console.log(c); // 11

vector2d times(vector2d other)

Returns the vector2d result of multiplying this vector2d with the other vector2d

var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.times(b); console.log(c.toString()); // QVector2D(3, 8)

vector2d times(real factor)

Returns the vector2d result of multiplying this vector2d with the scalar factor

var a = Qt.vector2d(1,2); var b = 4.48; var c = a.times(b); console.log(c.toString()); // QVector2D(4.48, 8.96)

vector2d plus(vector2d other)

Returns the vector2d result of the addition of this vector2d with the other vector2d

var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.plus(b); console.log(c.toString()); // QVector2D(4, 6)

vector2d minus(vector2d other)

Returns the vector2d result of the subtraction of other vector2d from this vector2d

var a = Qt.vector2d(1,2); var b = Qt.vector2d(3,4); var c = a.minus(b); console.log(c.toString()); // QVector2D(-2, -2)

vector2d normalized()

Returns the normalized form of this vector

var a = Qt.vector2d(1,2); var b = a.normalized(); console.log(b.toString()); // QVector2D(0.447214, 0.894427)

real length()

Returns the scalar real value of the length of this vector2d

var a = Qt.vector2d(1,2); var b = a.length(); console.log(b.toString()); // 2.23606797749979

vector3d toVector3d()

Returns the vector3d result of converting this vector2d to a vector3d

var a = Qt.vector2d(1,2); var b = a.toVector3d(); console.log(b.toString()); // QVector3D(1, 2, 0)

vector4d toVector4d()

Returns the vector4d result of converting this vector2d to a vector4d

var a = Qt.vector2d(1,2); var b = a.toVector4d(); console.log(b.toString()); // QVector4D(1, 2, 0, 0)

bool fuzzyEquals(vector2d other, real epsilon)

Returns true if this vector2d is approximately equal to the other vector2d. The approximation will be true if each attribute of this is within epsilon of other. Note that epsilon is an optional argument, the default epsilon is 0.00001.

var a = Qt.vector2d(1,2); var b = Qt.vector2d(1.0001, 1.9998); var c = a.fuzzyEquals(b); // default epsilon var d = a.fuzzyEquals(b, 0.005); // supplied epsilon console.log(c + " " + d); // false true
