Re: How to access Isopoint Cluster

[Fabricio Chamon]

maybe this (be sure to check if it is working properly):

var oObject = CreatePrim("Text", "NurbsCurve", null, null);
SelectObj("text.isopnt[(3,0.922)]", null, null);
AddToSelection("text.isopnt[(2,0.433)]", null, null);
AddToSelection("text.isopnt[(0,0.267)]", null, null);
AddToSelection("text.isopnt[(6,0.748)]", null, null);
AddToSelection("text.isopnt[(4,0.463)]", null, null);
var oCluster =
oObject.ActivePrimitive.Geometry.AddCluster(siIsoPointCluster,
"Isopoint_AUTO");
cElements = oCluster.Elements;
for(var i = 0; i < cElements.Count; i++)
    LogMessage(cElements(i)); // 0,1,2,3,4

var oSubComponent = oCluster.CreateSubComponent();
LogMessage("oSubComponent.Type: " + oSubComponent.Type); //
isopntSubComponent
LogMessage("ClassName(oSubComponent): " + ClassName(oSubComponent)); //
SubComponent

var aElements = oSubComponent.ElementArray;
LogMessage("oSubComponent.ElementArray: " + aElements.toArray()); //
LogMessage("oSubComponent.ElementArray.length: " + aElements.length); //
undefined

/////////////////////////////////////////////////////////

//get members as 1-item (string) collection (does not affect viewport
selection)
var isopnts = SelectMembers(oCluster, false, false);
var isopntsString = isopnts.getastext();

//manipulate string to parse into a Vec3 Array
//logmessage(isopntsString);
var aIsoPnts = IsoPntVectorArrayFromClusterString(isopntsString);

// Vector.X = subcurve index / Vector.Y = curve U
for (i=0;i<aIsoPnts.length;i++){
logmessage ("Cluster item " + i + " -> Subcurve Index: "+ aIsoPnts[i].x +
", U: " + aIsoPnts[i].y);
}


//string parser function
function IsoPntVectorArrayFromClusterString(inStr){

var listString = inStr.substring( inStr.indexOf("[")+1, inStr.indexOf("]") )
var listSplitString = listString;
var aSplitIndices = new Array();
while (listSplitString.indexOf("),")!=-1){
aSplitIndices.push(listSplitString.indexOf("),"));
listSplitString = listSplitString.substring(0,
listSplitString.indexOf("),")) + "#"+
listSplitString.substring(listSplitString.indexOf("),")+3);
}
listSplitString = listSplitString.substring(1,(listSplitString.length-1));
var aItems = listSplitString.split("#");
var aReturn = new Array();
for (i=0;i<aItems.length;i++){
var isopnt = XSIMath.CreateVector3();
var aValues = aItems[i].split(",");
isopnt.x = parseFloat(aValues[0]);
isopnt.y = parseFloat(aValues[1]);
aReturn.push(isopnt);
}
 return aReturn;
}
