示例1: direction
static VALUE direction(VALUE self)
{
Leap::Pointable * pointer;
Leap::Vector * vector;
Data_Get_Struct(self, Leap::Pointable, pointer);
vector = new Leap::Vector(pointer->direction());
return WrapVector(vector);
}示例2: convertPointableRotation
void convertPointableRotation(const Leap::Pointable& pointable, MatrixF& outRotation)
{
// We need to convert from Motion coordinates to
// Torque coordinates. The conversion is:
//
// Motion Torque
// a b c a b c a -c b
// d e f --> -g -h -i --> -g i -h
// g h i d e f d -f e
Leap::Vector pointableFront = -pointable.direction();
Leap::Vector pointableRight = Leap::Vector::up().cross(pointableFront);
Leap::Vector pointableUp = pointableFront.cross(pointableRight);
outRotation.setColumn(0, Point4F( pointableRight.x, -pointableRight.z, pointableRight.y, 0.0f));
outRotation.setColumn(1, Point4F( -pointableFront.x, pointableFront.z, -pointableFront.y, 0.0f));
outRotation.setColumn(2, Point4F( pointableUp.x, -pointableUp.z, pointableUp.y, 0.0f));
outRotation.setPosition(Point3F::Zero);
