ISUther Posted October 1, 2016 Share Posted October 1, 2016 (edited) I have a circle with setup that you see in picture and i have line I want line to be same shape as my circle is same lenght. I use used Circle because i failed to do good shape with curve tool And later discovered that circle does not have a point parameret option as line has.

konstantin magnus Posted October 1, 2016 Share Posted October 1, 2016 (edited) https://en.wikipedia.org/wiki/Circumference You can use the carve node to cut down the length of a curve. circle_length.hipnc sorry, rather this is what you meant.. circle_length2.hipnc Edited October 1, 2016 by konstantin magnus Quote Link to comment Share on other sites More sharing options...
ISUther Posted October 1, 2016 Author Share Posted October 1, 2016 Thank you for trying to help me. But i need to use a line not a "attribcreate" as if u take a look at atributecreate and line they have different settings. When you open up hip file i attached and dive inside and open up Geo Node named as VINE_PATH you can see what is happening. Sphere has points and those points "shoot" different directions where line is connected. In my case i need to shoot out only 1 line and that line needs to look similar as you see in my attached render view picture. That one line will be the vine for my logo that i try to create. and from that vine i will later grow smaller vines. May be (depending how it looks) i would twist one vine around another when they grow Got any idea how to do it? Vines.hip Quote Link to comment Share on other sites More sharing options...
konstantin magnus Posted October 1, 2016 Share Posted October 1, 2016 the attribcreate is just there to check whether the line and the circle segment have the same length (basically if my math is correct). the actual calculation happens in the carve node. play around with the carve node or the creep node to simulate growth quickly.

ISUther Posted October 1, 2016 Author Share Posted October 1, 2016 (edited) Audio is a bit out of shape but i will explain problem here: At the moment i need to figure out how to create only 1 similar name it as u want: tenticle, vine, stiv And later grow smaller ones from that main one.

ISUther Posted October 1, 2016 Author Share Posted October 1, 2016 Hi, I did try that one. It did not work out as i expected and wanted. Here is video where i explain my issue a bit more detailed. Was able to make some changes. As key here is that i need main smaller vines grow from main vine and then from smaler vines grow leaves 3 on one side of stiv and 3 on another side of same stiv. , Quote Link to comment Share on other sites More sharing options...
konstantin magnus Posted October 1, 2016 Share Posted October 1, 2016 i dont know if someone is able to help you that way. its probably more useful to concretize your questions (in short and precise written words). posting hip files also saves time so others can see whats going on.

ISUther Posted October 2, 2016 Author Share Posted October 2, 2016 I researched and found a answer. Need to find good turtorials on L systems on houdini. That is where you grow stiv and smaller sivs from main stiv I will try to search them. Thank you for trying to help. Tutorials linked above are not good for my example. If you take a look at this: He has over there tree that grows (time frame 00:30) there you see main stiv and smaller stivs grow from main stiv. I do not need butterflys and stuf i just need main stiv that i can adjust (thickness and lenght and texture on surface) and then select in system how many stivs will grom from main stiv. or another idea to make plant grow is this way as you see here: Quote Link to comment Share on other sites More sharing options...
rbowden Posted October 3, 2016 Share Posted October 3, 2016 Everything you need to know about L-systems is right here:http://algorithmicbotany.org/papers/abop/abop.pdf Its a hefty read but, totally worth it. It will help you understand the rules of lsystems if you are really into it. Making the branches off a curve like you are asking is actually not as trivial as you think.

ISUther Posted October 4, 2016 Author Share Posted October 4, 2016 Here is example where idea that i have all the time in my head is used.http://www.blur.com/work/project/the-girl-with-the-dragon-tattoo/ When you pause the vido and scroll to time frame 01:10 you see vines grow and they have texture and do not look booring and crap. Wat method is done creating this growing root). Used loads of model sequence from zBrsh some how? Or used some ohter method to creae growing vines / stivs ? Color, music, blurr and ohter stuff is not important to me at the moment. I need to create / want to create growing root effect like that. Here is also image of roots. Ofcourse i need to change the root a bit so it evolves in to half U shape that i want. Quote Link to comment Share on other sites More sharing options...
