VertexController speed

[cyberkilla]

Egon, how costly is using a VertexController, in a case like skeletal animation,
when you need to have mesh access for almost every frame?

[EgonOlsen]

Not much! The critical parts are in your hands, i.e. in the implementation of the actual apply()-method.

[cyberkilla]

Oh, well that is no good!

Now I have nobody else to blame when I try it later, and it runs slow;)

Actually, I think it should do fine. Im going for proper skeletal animation
for now, instead of the mesh keyframes(cant explain why, it just happened that way)

Im trying to keep everything neat, and documented, because I'd like to see if somebody would test it for me soon.

One more thing...Egon, your XML reader...I will use it:) At the moment, im using jdom, because I had it set up already, and knew how to use it.
Your xml parser looks nice and simple, and it seems to be DOM also, so no problems here:)

[EgonOlsen]

The XML-parser...yes, it's very simple. Maybe too simple. If it's missing something, please let me know. It's something that i had written just because i had nothing else to do. It's far from being perfect, i guess.

[cyberkilla]

The only things that come into common use when I use jdom, are...

node.getChild("name")
First child node found is returned.

node.getChildren("name")
Returns all child nodes in a List.

node.getAttributeValue("name")
Returns value of attribute if found.

node.getText()
Returns contents of the xml node.

node.getChildText("name")
Returns contents of a child node.

Everything here seems to be implemented in some way, in your parser,
so it should be okay for now:) I hope;).

As you can see, those methods are merely convieniences.

Modifications to be like jdom....
What im using for skeletal api, because it is a million times faster then
changing lots of code:P

public class XMLParserFactory
{
private static XMLParserFactory defaultInstance = new XMLParserFactory();

public static XMLParserFactory getInstance()
{
return defaultInstance;
}
public XMLElement parseXML(String input)
{
return new XMLElement(XMLFactory.getInstance().parseXML(input));
}
}


public class XMLElement
{
XMLNode node;

public XMLElement(XMLNode node)
{
this.node = node;
}
public XMLElement getChild(String name)
{
Vector nodes = XMLFactory.getInstance().getMatchingNodes(node.getName()+"/"+name,node);
if(nodes.size() == 0)
return null;

XMLNode newNode = (XMLNode)nodes.get(0);
return new XMLElement(newNode);
}
public List<XMLElement> getChildren(String name)
{
List<XMLElement> elements = new ArrayList<XMLElement>(20);
Vector<?> nodes = XMLFactory.getInstance().getMatchingNodes(node.getName()+"/"+name,node);

for(Object o : nodes)
elements.add(new XMLElement((XMLNode)o));

return elements;
}
public String getAttributeValue(String name)
{
String value = node.getAttributeValue(name);
return (value.length() != 0) ? value : null;
}
public String getText()
{
return node.getData();
}
public String getChildText(String name)
{
XMLElement element = getChild(name);

if(element != null)
return element.getText();
else
return null;
}
}

I am just too used to the jdom conventions, i suppose:)
