Thanks again DaJuice, this seems to be more or less EXACTLY what I wanted to accomplish. I am currently upgrading my 3d workstation so I wont be able to check it out until next week or so. I had a quick look at it before I started taking my puter apart. I couldnt get the texture aproximation to work. I probably did something wrong whn rendering it though. I will get my hands dirty with houdini and this prject as soon as my new pc is up and running.
Hats off DaJuice!

It responds very slow when I animate, cooking takes a long time. Seems strange to me, I mean it only generates a few thousand boxes to provide points and then theese points are grouped and given box each to display. Why is it so slow? Can I use particles to generate the pointcloud instead? Would that speed thingsup?

Hej!
Welcome aboard, I am checking out the buzz videos.
Good stuff, I think after some time me and Houdini will become very good friends.

DaJuice you are too modest!
“For example, I haven't tried to sample the texture and assign each point an averaged color. Also the division box hasn't been parented to the head in any way, nor does this example show any animation.”
Jesus, you did a lot for me! Thanks a million! I think I?Lll scrap my old 3d software just for the communityside of houdini!

Wow!
I am very impessed with how fast you answered my question, thanks!
Well the reason I want to do it in 3d is that I dont want it to look like an effect but as something that is really happening to him, a part of reality so to speak. When the actor rotates his head or the camera moves around him it will obvious that his face is infact made of boxes.
Simon that sounds like a great idea, I dont have a clue how to do it but I ill try my best! It is very important that the boxes all have the same size and that they are placed “side-by-side” if you know what i mean. I think that your idea could do this(well i sounds so to me anyway). So basicly I can create an 3d array of points with lets say 50mm apart and if these points are inside the “head object” the are assigned to a group, this group are given a box each to display? I guess I could project a blurred version of the filmed material as a texture projected from the camera through the whole cubeobject to get around the texture issue…

Hi! I am completely new to houdini, the reason why I am trying it out is that I am trying to produce an effect I find difficult(or impossible?) With other 3d softwares.
What I am trying do is a sort of pixelated effect in 3d. Basicly an actors face wil slowly become more and more pixelated. This I am thinking solving in the following way:
1. Build a 3d replica of his face in 3d using imagebased modelling.
2. Match this to the footage including the movements of facial features such as jaw.
3. use this replica as a base to produce boxes filling the space of the replica face. I want theese boxes to be "static to their own positions so if the jaw moves for example the boxes will not move but ne ones will be created in the space where the jaw enters. The boxes will however follow the movements of the head in space.
4. I want these boxes to take the color of the avarage of underlying pixels of the texturemap on the replica head.
Does thet make any sense?
I am sure that this effect is doable in houdini but I dont have any idea where to start. Should i go for particles or some modeling approach?
any ideas out there?
