Very good work :)
No sorry, I don't have working experience with very large trees such as yours.
Yes, it's possible to reduce the length between the father and the children nodes, if that's what you mean by "space lost by the edges". It's the "length" variable in the HTModel class.
Hope that's help.

I forgot to mention, that I already made a number of adjustments to improve the performance of hypertree:
- The renderer 'prunes' the tree, when it detects that there is not enough space available to render a subtree.
- During animation and interaction, the tree is rendered without antialiasing.
- Rendering is done in two threads to take advantage of multiprocessor machines.
I still...

Hi there,
Das anyone have experience with visualizing very large trees?
I mean trees with 500'000 nodes and more.
I noticed, that a lot of visual space is lost by the edges.
Is it possible to increase the density of the tree, so that more nodes fit onto the display at the same time?
TIA,
-Werner.

No problem ! You don't bug me, don't worry :-)
It's better to ask than to spent too much time when a fast answer could resolve it fastly.

Well turns out i didnt update the jar file correctly. sorry, once again, my careless mistake. spent hours before realising what a stupid thing i was doing putting the new class file in the wrong directory! It works now. Here is my code anyway:
public void mouseClicked(MouseEvent e) {
if (e.isShiftDown()) {
model.restore();
} else if (e.isControlDown()) {.

It should have worked, it seems to be the right thing to do fo me. Can you send me your code of the mouseClicked method, or at least of the part you've modified ?

hi,
im back! :)
Currently the tree reorients itself on left as well as right clicks. I was trying to disable reorienting the tree on right clicking because i want the node that is currently focussed on to stay at the center on just a right click because i want to highlight it with a different color. I tried to modify the mouseClicked method inside HTAction class to check for right click...
