nodes

I use the force layout in D3.js v4. Now I want to click on a node and use the force physics like collide for that one node only. The simulation for every node on the entire SVG is this: var simulation = d3.forceSimulation() .force("link", d3.forceLink().id(function(d) { return d.index })) .force("collide", d3.forceCollide(function(d) { return d.r + 8 }).iterations(16)) .force("charge", d3.forceManyBody()) .force("center", d3.forceCenter(chartWidth / 2, chartWidth / 2)) Now I want to change the collide behavior for the one node I clicked on to push other nodes away or attract them. Is there

In a cpp plugin I am developing in Maya API, I register a custom MPxTransform Node in the initializePlugin function: status=pluginFn.registerTransform("mympxtransform", myMPxTransformClass::id, &myMPxTransformClass::creator, &myMPxTransformClass::initialize, &myMPxTransformMatrixClass::creator, myMPxTransformMatrixClass::id); And then create the node programmatically: MDagModifier mdagmod; MObject MyMObject; MyMObject=mdagmod.createNode("mympxtransform",MObject::kNullObj,&status); I can see the node properly created in the outliner. But now, how can I access my custom myMPxTransformClass from

I gather that the whole point of a DocumentFragment is to be able to construct the contents without touching the DOM until it’s ready to go. Given that DocumentFragment doesn’t support innerHTML , it can be a bit tedious. On the other hand, once constructed, it’s easy to add the contents to an existing DOM node by the fragment itself. If I create a div without adding it to the DOM, I can populate it how I like, including innerHTML . As far as I can tell, it should have no additional impact on performance. Is there a simple way (ie in one line or so) to copy the contents of an existing DOM node

My Tree/Node Class: import java.util.ArrayList; import java.util.List; public class Node<T> { private T data; private List<Node<T>> children; private Node<T> parent; public Node(T data) { this.data = data; this.children = new ArrayList<Node<T>>(); } public Node(Node<T> node) { this.data = (T) node.getData(); children = new ArrayList<Node<T>>(); } public void addChild(Node<T> child) { child.setParent(this); children.add(child); } public T getData() { return this.data; } public void setData(T data) { this.data = data; } public Node<T> getParent() { return this.parent; } public void setParent
