(293 KB) well doc is still being done and not completed at all so i need to work on this later on in next few weeks and also other things like i’v indicated in first post but it’s easy to use just select one of the spiral or helix and a new panel will appear in the Tool pro panel where you can change some of the parameters like Z for height / turn and radius ect try it and see what happen i added many differrent type of spirals so you have many choice available here! Here is a pic for the main menu with list of items. I will never be without a spiral! A lot of things in nature are based on various types of spiral so these could be a very good basis for natural objects:D. 1- t’s possible the Cornu is not working yet but i’ll review it later on got to admit this one is the most difficult of all! 2- Your Golden spiral with Z value well i already have a fibonaci function check it out just look at the the archemedes spiral it has a Z value which you could use but instead of having a Z value / turn it could change for something else like delta Z following the Fibonaci serie that should be easy to do the only problem i 'm not cetain is how do you get the side walls on it for the tower as a spiral 3D let me know if you find how to do that i can include it in a function!
3- i’m looking for an helix along a path in 3D if you see anything let me know! Hope it helps happy 2.5. Yes that helps.
Great to know I’m on the right path. BTW I included the tower to show the basic principal of the curve. I don’t want to model the tower itself, but it could make an interesting project for someone. EDIT: I just spoke to Dan Winter who uses this spiral in his physics (for example he produces a water imploder device that uses it). He confirmed to me that it is in fact, not the Fibonacci Spiral, but the Golden Spiral that I need to be looking at (Golden Spiral 2 in your script)). The Z axis can apparently be calculated with x2squared+y = radius, then radius.
golden mean = the Z value. I got a Z dimension for your Golden Spiral 2. But I am having trouble getting the Z dimension “stretched” enough to match the golden mean proportions on the X and Y axis. I assume the value ANGTR is important so that the Z plot matches the turns of the X/Y spiral (removing it or putting it in wrong leads to plots that go all over the place).
I got closest with ANGTR htphi. Attached are a couple of my results.
I think I’m very close but I have some bad maths teaching in the way from my past. My maths teacher used to shout at us and I have fears instilled in me from having to wrote learn those awful times tables.BTW I’m not trying to ask for sympathy, this is just a sad fact of very bad maths teaching.
It’s probably a miracle I can even look at these equations and understand some of it. Well the angtr= ang value in radians is just the radians value of the angle cause the loop works with angle in degrees and the X Y values with cos and sin needs the radians values! So don’t worry about it PHI value is from one of the site which described the Golden spiral using phi so i did not really invented anything for this one just applied the equations from the site! I could change it and works only with radians but i prefer to see angle in degrees its’ easier to visualize it!
Z vs turn one turn is 2 PI radians =360 Deg and it simply means that for one full 360 degrees turn it will be raised by a certain amount per/turn and this delta z value can be defined as anything you want you could make = to phi / turn if that what’s you want! What kind of name can you put on this new one is it sort of a golden spiral with Z being golden too? As soon as i get the new name i’ll upload a new version in first post! It’s more a compromise you can copy any class / function to another script - easy and simple to read and understand for anybody i can try to simplify it but then it would become more difficult to read and understand! Mind you this will be a little bit longer when i introduce my new 2 levels menu soon i hope but more complicated for noobies to understand! The important thing for me was to give lot’s of flexibility with different type of Spiral and Helix at least compared to what we had in 2.49 which was very limited! Have fun with spirals/Helix you can always suggest ways to make it shorter if not too complicated now i still prefer to keep it realtively simple and easy to read!
But shoudl wait till i come up with the new 2 levels menu system thanks happy 2.5.
