Class MHVector

A vector represents a magnitude and a direction. It has three components x, y and z. The vector can be visualized as a line segment that starts at (0, 0, 0) and ends at (x, y, z). The line length is the magnitude.

Member Variables

MHVector(void)

Default constructor, creates an vector with x, y and z set to zero.

MHVector(MHFloat newX, MHFloat newY, MHFloat newZ)

Constructor, sets x, y and z to the provided values.

MHVector(const MHVector &source)

Copy constructor, creates an MHVector that's a copy of source.

MHVector crossProduct(const MHVector &vectorTwo)

Returns the cross product between this vector and vectorTwo.

void fromQuaternion(const Quaternion &source)

Before calling fromQuaternion, this vector should have one or more of x, y or z non-zero. We create a Point3D at (x, y, z) and rotate it by source. The resulting position is stored as the new vector. If only one of x, y or z is non-zero, we're essentially taking a forward direction and causing it to point towards the direction given by the quaternion.

MHVector normalize(void)

Returns a vector with the same direction as this one, but with a length of 1.
