Example: Up-vector constraint

This dotXSI fragment shows a cube that is position-constrained to a cone and direction-constrained to a grid. The cube also has Up Vector constraints to a sphere and a null object. The Up Vector constraints are nested within the constraint that they affect.

   SI_Constraint cube1-POSITION
   {
       "cube1",
       "POSITION",
       1,
       "cone1",
       SI_Constraint cube1-UP_VECTOR
   {
          "cube1",
          "UP_VECTOR",
          1,
          "sphere1",
       }
   }
   SI_Constraint cube1-DIRECTION
   {
       "cube1",
       "DIRECTION",
       1,
       "grid1",
       SI_Constraint cube1-UP_VECTOR
       { 
          "cube1",
          "UP_VECTOR",
          1,
          "null1",
       }
   }
 // When upvct_active is without reference (not assigned to a specific object but set to affect a specific axes) then it is exported as follows:
   SI_Constraint cube1-DIRECTION
   {
       "cube1",
       "DIRECTION",
       1,
       "grid1",
       SI_Constraint cube1-UP_VECTOR
       {
          "cube1",
          "UP_VECTOR",
          0,
       }
   }
