1. Center Of Gravity Simulation

Hi everybody! Could u help me? I have to simulate a the Earth and continental plates sliding on it. Simple faking is not suitable for the job I am specifically entrusted to create a simulation enviroment to this. I have some ideas, but am curious how would u do that? It has to contain the ability to create cracks, to give them a width, and the ability to collide plates which result ridges, mountains. Simple gravity force - I think - is inadequate since it does not allow u to pull material towards the center of gravitation (in nonhoudini apps), it just allow u to use the x and y directions. Thank u -------------------------- Some more details of the job: I feel I can share more infos. Goal: creating a simulation system which could present the ... mainly geological theory. Not plate tectonics, but in the same field, that is how continents formed, how oceanic ridges and trenches formed, giving answers for the shape of the Earth (buckled downward in the western Pacific area ...), how oceanic canyons and land canyons were formed, how layered strata was formed, how fossisls were formed, etc.... The system must have the capability to follow changing driver parameters, as more research shows something new... So it is a very complex system based on a complex theory. It would be great if I (or someone else) would be able to make just a part of it, especially the next ones: 1. The Earth's crust cracks, this crack widens 2. Water erupts from beneth the crust through the cracks, the cracks widen, sediment spreads on the surface of the Earth 3. As the cracks' width reach a certain given amount the underlying crust buckles upward, the plates above this slide away from the rising floor. As the underlying crust are buckling upward the opposite side of the Earth sinks downward. 4. The sliding plates run into resistence, compresses, forming mountains, plateaus, ... Future plan is to make a simulation on the forming of the Grand-Canyon based on this theory. The above detailed simulation is driven by some key parameters: I. The stiffness of the crust, the mass (global average, or local), collision parameters 2. The cracks' widening 3. Time 4. Gravity at least by these.

Ok thanx
4. Houdini 9?

can I download houdini 9, what are the prerequisites of doing so, is this a public beta?
5. Houdini Demoreel

Hello dear Houdini users Could anyone of u post a link where I can download a Houdini Demoreel if exists. Thanx
6. Houdini Demoreel

Is there a newer Demoreel for Houdini, and a link to it? Thank u.

http://www.cgchannel.com/news/viewfeature....jsp?newsid=3043 This site says that Houdini 7 public beta is downloadable, but I am not able to find the requested file. Is this version exist?
8. Water drops on a surface

Hello Houdini users Could u help me again? Could u post me a link or a short description how to make the following effect. I have to do a surface on which waterdrops are running down. Thank u.
9. Water drops on a surface

Ok, I managed the problem by copying the geometry onto the surface, I needed just a still image, it was ok.
10. How to ewxport to 3d paint package

Good morning Houdini users Could u help me? I'd like to paint my models in a 3d paint package (BodyPaint 3D, or DeepPaint 3D), how to do the connection between these apps and Houdini? Thanx
11. How to ewxport to 3d paint package

The method u mentioned works hand in hand between Houdini and MAxon's BodyPAint v. 2.

13. Speeding up

Good morning, could anyone of u help me in this issue: I am loosing speed, when the modeling progress requires more nodes to attach. Is there any trick on how to cook the nodes, or how to hybernate the nodes which doesn't require more work on themselves? I've tryed saving geometry to disc, and reloading that into the network, or collapsing the nodes mentioned into a subnetwork, but after a point these can not help. I work on a full figure, a statute, with much detail, It contains about 16000 vertices, but now the workflow is slowing. Thanx for your help.
14. Speeding up

Thanx for the reply, Locking the node above the present one seems to be the best method, coupled with collapsing into subnetworks, the experimentation'd showed it.
15. Speeding up

Meanwhile I have found a would-be solution, I will experince with it. 1. Method: Lock the node above the present one, itt will cook everything and save that to this node. 2.Delete History saves all previous nodes into the now activated node. Other advices?
16. Rigid Body Tutorials

There is a Techimage tutorial and downloadable files for animating a branch which hits the wall and the bricks fall
17. Realsitic Candle Flame

I' ve tryed some methods creating fire in Houdini, but I am not able to do a long flame for a candle flame, could anyone help me how to create realistic flames, like candle flames, gas flames, which are not so turbulent than the usual fires

19. Realsitic Candle Flame

No, where can I find that? Thanx
20. How do I connect curves

Dear Houdini users Could u help me? How do I connect two separate curves which later I want to handle as if they were one. I want to connect the endpoint of the first one to the starting pont of the second one, weld these points and make the curve closed. I could do it in Adobe Illustrator (not a procedural system), but I think it is a simple task Houdini should handle. Later I want to extrude this curve. Also it is a basic task in Cinema 4D. The merge op is not sufficient, their points should be welded or more points added if needed. Thanx
21. How do I connect curves

thanx that did the job
22. Houdini scenes complexity?

1 300 000 points? Tremendous amount. It is a number rarely used for interactive 3d processes, even in movies.

Thanx a lot
24. Growing Lsystems within a volume

I have completed the houdini tutorials, and found that I can not grow Lsystem geometry within a volume could anyone post a good hip file and some description how to do it? Thanx
25. Growing Lsystems within a volume

I have completed all the tuts and exercises in the docs u mentioned, and the last one did not come out as expected. Meanwhile I have found the error. The error is in the tutorial picture which connects the volume into the first input of the Lsystem operator instead of the correct one that is the last input the m input. When I interchanged these everything'd worked right. Thanx
