Method Detail

E

void E(IOrientation o)

Copies the given orientation to this one.

Parameters:

o - the new orientation

getDirection

Vector getDirection()

setDirection

void setDirection(Vector newDirection)

Sets this orientation to point in the given direction.

Parameters:

newDirection - the new direction for this orientation

Throws:

java.lang.Exception - if vector has 0 length

randomRotation

void randomRotation(IRandom random,
                    double theta)

Perform a rotation by a random amount in the solid angle theta on the present orientation.

Parameters:

random - random number generator used to select the angle

theta - the maximum angle (in radians) for random rotation
