I have a curve. I have done some calculations and made it in to multiple prims.Right now I have a set of primitives (some of them connected primitives and some of them not connected). I want to join all the connected primitives in to a single primitive.When I did that some of the primitives are disappearing.I found that the primitives are not in order and that is causing the problem.I tried to use the sort sop in order to make all the prims in order(number wise).But none of the options in sort sop resulting the same.Could any one please tell me how to go for it.

I have a curve(single primitive) with points of different colors( red, green yellow).I want to partition this curve in to multiple primitives.For every color change across the curve,I want a different primitive.Could any please tell me how to go for it.

Hai ,
I am working on procedural generation of roads. The technique I am following is iterated subdivisions. At present I have a 10 * 10 grid with 2 rows and 2 columns. I resampled the edges such that I have 50 points on each edge.I need to select a random point on a random edge and then draw a line such that it bisects any other random point on the grid forming 2 polygons.Could any one please help me on how to achieve this in houdini….Thanks in advance….

Hello everyone,
I would like to create a digital asset in houdini for generating procedural roads.Could any one please tell me whether I could find any existing plug ins for the same in any other software. If any one has already done a digital asset on the same, could you please give some kind of resources in order to generate the roads procedurally.

Thankyou very much for your help Keon.I appreciate it.I copied the toolkit folder to my home directory I hope it compiled well,I got the following message after typing hcustom -s geoisosurface

Thank you very much for your help.I am a newbie to programming in HDK.After
typing hcustom -s geoisosurface.C in the standalone folder in the terminal,I got the following error .

Could anyone please help as I got no clue of what exactly is that.

I am very much interested in writing some plugins in houdini using hdk.I followed the steps given in sidefx website in using the hdk.
I tried to open a program from /Library/Frameworks/Houdini.framework/Versions/10.0.528/Resources/toolkit/samples/standalone/ from command line of my macbook.
I tried to open a program using hcustom command in standalone folder,but I couldn't since I got the following error:
-bash: hcustom: command not found
Could anyone please tell me how to include the hcustom command in .profile file on mac.Thank you.

Thanks a lot Graham and Chan.After changing the default value to 0 in stamp function,it started working.

Hai,
I have taken a grid sop and tried to clip it using a foreach sop.I made it for each number for range 1-10 and the stamp name is FORVALUE.Inside the foreach sop I have appended a clip sop after each sop.In the clip sop I have made the direction
x=sin(rand(stamp(“..”,“FORVALUE”,“”))*180)
y= 0
z=cos(rand(stamp(“..”,“FORVALUE”,“”))*180)
and then keep all primitives.
After doing that the whole network turns red.
I clicked the middle mouse button on the grid.It says
“the sub-network output operator failed to cook.”
/obj/geo1/foreach1/clip1.
I am on mac and houdini 10.0.528 apperentice version.
