Well, there are both options; but I think individual points will be easier to render.
You can watch this: http://vimeo.com/41377003
If we convert the point clouds to objects, and then stream them frame by frame, I think it is not feasible, both from the computation part and the bandwidth...What do you think?
If we could do something like this in jPCT AE, it could be really nice :-/

Yeah; Thanks a lot 
Btw, so we should put all the downloading stuffs in the 2nd thread, and just put the addObject to the main thread. The threads are concurrently being executed; so when reaching the addObject, how should it find out if that specific object was already downloaded in the 2nd thread, so to add it now?! 

Egon, a strange problem:
I found out when I want to load Serialized Objects from the web, the demo hangs/crashes!! for other file types (.obj, .md2, .3ds) everything works. Is there anything happening here which I'm not aware of?
(btw, it is in a second thread.)

grass = Loader.loadSerializedObject(stream("sergrass.ser"));
tm.addTexture("grass", new Texture(stream("grasstex.jpg")));
grass.setTexture("grass");
grass.translate(-85, -17, -70);
grass.rotateZ((float) Math.PI);
grass.setTransparency(10);
world.addObject(grass);
grass.strip();

Hi,
In my demo, I've got almost 20 objects and corresponding textures. Everything at this moment works, but when I just change one of these objects to be downloaded from somewhere, I get out of memory error. Is there any tips for that?
(Finally I have to download all of these 20 objects, similar to waterput)

Here after getting the .md2 file, I add it to the world.
waterput = Loader.loadMD2(stream("waterput.md2"),1f);
tm.addTexture("waterput", new Texture(res.openRawResource(R.raw.waterputtex)));
waterput.setTexture("waterput");
waterput.clearAnimation();
waterput.translate(170, -35, -130);
world.addObject(waterput);
waterput.strip();

This is the method which gets a name, receives the object from a URL and returns it.
BufferedInputStream stream(String name) throws IOException{
//TODO
String objURL = "http://www.xxx.edu/xxx/"+name;
URLConnection conn = new URL(objURL).openConnection();
conn.connect();
BufferedInputStream bis = new BufferedInputStream(conn
.getInputStream());
Loader.clearCache();

return bis;
}
btw, I do not need all the keyframes in the .md2 files, so I call clearAnimation() to remove them.

Hi there,
Is there any difference if we use colored texture (say green) or load a green image file (say a .png file)?  in terms of rendering overhead, or anything?
thanks

Egon,
I've a problem with a PNG texture, in which the background is transparent. in the game, the background gets black. What should I do?
attached is the grass texture!!!

I see. Removing them seems to be a bit hard!
Well, I'm using a .md2 model viewer, and it says it has 16 frames and 554 triangles.
One of them which after removing, things got better, had 198 keyframes!! however the size was just 250kB.
