<p>Hello,</p>
<p></p>
<p>lately I have been investigating on conjugate curve networks and I was surprised to find so little information on it in this forum. The little bit I found was regarding <a href="http://www.grasshopper3d.com/xn/detail/2985220:Comment:239536" target="_blank">a comment by Daniel Hableton</a>, hence this is mostly address to him. But I thought I might receive more that I bargained for by making it open, and others might also benefit. </p>

<p>Hello,</p>
<p></p>
<p>lately I have been investigating on conjugate curve networks and I was surprised to find so little information on it in this forum. The little bit I found was regarding <a href="http://www.grasshopper3d.com/xn/detail/2985220:Comment:239536" target="_blank">a comment by Daniel Hableton</a>, hence this is mostly address to him.

<p></p>
<p>PQ meshes can be obtained easily (almost self arising) from conjugate curve networks, also called conjugate direction fields (CDF). This makes them critical to the design and more importantly to the control of PQ meshes, i.e. by controlling the layout of the CDF, the layout of the PQ mesh can be controlled. The principal directions of a surface make up a CDF, but since they are unique they offer no degree of freedom. Furthermore CDF are involve in the design of developable strips. </p>
<p></p>
<p>I was interested in knowing how to obtain CDF other than those of the principal directions. These seem to have been obtained by Daniel with the SPM toolset. A reference paper or general approach to the matter would suffice. </p>

<p>Hi all,<br></br> <br></br> I've been doing a uni project involving points and fields of influence. Basically what I've been trying to achieve is a series of points (A) that have a field of influence on a series of points (B). I have managed to achieve this without SPM components but its not very variable. I was guided to the SPM components as I was told they would suit what I need better.

<p>Hi all,<br/> <br/> I've been doing a uni project involving points and fields of influence. Basically what I've been trying to achieve is a series of points (A) that have a field of influence on a series of points (B). I have managed to achieve this without SPM components but its not very variable. I was guided to the SPM components as I was told they would suit what I need better. I've made a script with a gravity sink but I think its the wrong component for my needs as points just start shooting off once they reach the attractor.<br/> <br/> What I want of them is to be able to vary the intensity of the fields of A individually, even turning some completely off. I want them to cluster around the points A depending on how strong the pull is. I think I may need to manipulate lists in some way to do this but I'm not sure as I'm still sort of new to this.<br/> <br/> Any help would be great,<br/> thanks</p> Object Collisiontag:www.grasshopper3d.com,2012-04-22:2985220:Topic:5821732012-04-22T19:15:53.015ZDaniel Hambletonhttps://www.grasshopper3d.com/profile/DanielHambleton

<p>Hello community,</p>

<p>I'm looking for references to simulate fluid systems ins Grasshopper. More precisely I want to simulate the behavior of a substance (real or pseudo-physical) which collides with obstacles or multiple substances behaving in a reaction-diffusion manner.

<p></p>
<p></p>
<p>I have tried doing something similar creating a main Vector Addition and several Gravity Sources. But the forces add up exponentially and the points travelling through the vector field kind of go wild hehehe. It would be easier if the forces would add up linearly (Do you know what I mean?). Is that possible?</p>
<p></p>
<p>Plus, would it be possible to duplicate the points travelling through the vector field regularly, and start branching out like it is shown in the video?</p>
<p></p>

I'm beginning to think that some means of restarting the interpolation (perhaps with a counter) is what I need to work it out, but am not sure how to do so or if that is the proper solution. I've included the Rhino and Grasshopper file and would appreciate any feedback. </span></p>
