Below is a function that creates a null on each point of any input object (poly
, nurb, or cloud). It can be parsed and made into a command button which will
work on any selected object. It should be pretty easy to hack if you need to
replace the nulls with your own collection of objects:
function NullsOnPoints(inObj)
{
// If nothing input, use the selection
if(!inObj) inObj = selection(0);
// Get global transform from inObj
var gTrans = inObj.kinematics.global.transform;
var pTrans = XSIMath.CreateTransform();
// Get point collection from inObj
var points = inObj.ActivePrimitive.geometry.points;
// For each point, create a null and transform it to the point
var rootNull = ActiveSceneRoot.AddNull('PosNulls');
for(var i=0; i<points.count; i++){
// Get position vector of point
var pos = points(i).position;
// Multiply position by the global transform of the object center
pos.MulByTransformationInPlace(gTrans);
pTrans.SetTranslation(pos);
// Create null and set global transform
var node = rootNull.AddNull('pnt' + i + 'Null');
node.kinematics.global.transform = pTrans;
}
}
// END FUNCTION -- ---- ---- ---- ---- ---- ---- ---- ---
