Public Member Functions

 NegYDirection ()
 
- Public Member Functions inherited from SimTK::CoordinateDirection
 CoordinateDirection (const CoordinateAxis &axis)
 Implicit conversion of a CoordinateAxis to a positive CoordinateDirection along that axis. More...
 
 CoordinateDirection (const CoordinateAxis &axis, Negative)
 Explicit creation of a negative CoordinateDirection from a CoordinateAxis. More...
 
 CoordinateDirection (const CoordinateAxis &axis, int direction)
 Explicit creation of a CoordinateDirection from a CoordinateAxis and a direction calculated at run time. More...
 
CoordinateAxis getAxis () const
 This is the coordinate axis XAxis, YAxis, or ZAxis contained in this CoordinateDirection. Use getDirection() to determine whether this is the positive or negative direction. More...
 
int getDirection () const
 Returns 1 or -1 to indicate the direction along the coordinate axis returned by getAxis(). More...
 
bool hasSameAxis (const CoordinateDirection &dir2) const
 Return true if this direction and dir2 are along the same axis, even if the direction along that axis is not the same. More...
 
bool isSameAxisAndDirection (const CoordinateDirection &dir2) const
 Return true if this direction and dir2 are along the same axis, and in the same direction along that axis. You can also use operator==() for this comparison. More...
 
int dotProduct (const CoordinateDirection &dir2) const
 Perform a specialized dot product between this coordinate direction and dir2; returning 1 or -1 if they contain the same axis and 0 otherwise, without performing any floating point operations. More...
 
int crossProductSign (const CoordinateDirection &dir2) const
 Return the sign that would result from a cross product between this coordinate direction and dir2: 0 if they are along the same axis; 1 if the result would be in the positive direction along the third axis; -1 if it would be in the negative direction. More...
 
CoordinateAxis crossProductAxis (const CoordinateDirection &dir2) const
 Return the coordinate axis along which the cross product of this coordinate direction and dir2 would lie: same as this if both contain the same axis (doesn't matter because the sign would be zero); otherwise, the third axis that neither this one nor dir2 contains. More...
 
CoordinateAxis crossProduct (const CoordinateDirection &dir2, int &sign) const
 Return the axis and sign along that axis that would result from a cross product between this coordinate direction and dir2; this combines the functions of both crossProductAxis() and crossProductSign(). More...
