Parametric Structure & Animation

 


For this week, we had to make an GIF animation showcasing parametric structure.

Originally, I planned to a firework since I thought by using parametric factor, I could adjust objects' scale and number, as well as the length of the objects' axis.


Process

First of all, I made a system where I can change length of my base axis. To do so, I used number slide and made changes to the location of the starting and ending point of the line, as well as the length of the line.
After figured out one line, I made another set of the system and edited the range of the number slide, from "0<20" to "-20<0." Below are how it looked like.




With 2 individual number slides for each axis, I couldn't control them at the same time. So after researching, I used "Remap" feature, which allows me to adjust the values of two number slides at the same time. Below is the sketch of the structure.




I made Heart looking shape, assigned it to "Brep." And did "Move"d and "Scale." Personally, I don't remember seeing the lines that are coming out from the base object during the class, so it felt weird to me.

< Base Object > 

< Unfamiliar lines derived from base objects >

< Divide Curve - Line - Move >



Another troubleshoot happened while trying to figure out the problem above and adopted "Scale." Now the objects are scaled and hanging out outside of the axis.


< Move & Scale Functioning wrong >



I tried to use "Rotate" on two vertical lines that I made, however it didn't work. So as a solution, I changed the value of construct point directly and made them into horizontal lines. I soon realized the problem that, in that case, I can make the line rotated, but not the objects. Below is the captured problem.


< Another set of horizontal axis made, by connecting mapped value to Y value of "Construct Point" >



While playing with scale, I thought I found the effect that I like to use. As shown in the pictures below, the base objects that are moved on the axis scaled, and at the same time the length of the axis got longer.





< Possibility >



After figure out what made this possible, I remade the parametric system from the scratch. Below is the result.


< Highlighted part with green color, used straight line as base axis >


< When used curved line as base axis >



<By using "Move", "Scale" and "Rotate", I could yield multiple set of objects>



After yielding the effect that I liked, I copied the parametric system and assigned them to multiple different curves for dynamic results. Of course all of those could be controlled with one number slide. each set was connected to "Subtract" with different B value.  And considering the time that I can contribute more and the size of the file, I changed my original plan, from making firework to making bursting heart instead.

< Material added on the heart >




Final

 
< From left top and clock wise, Perspective, Front, Top, Right view >

< Final Animation >

I like the final result, however if I could understand the "Scale" better, I think I can make more controlled object next time. It was nice to find "Remap" feature. This result was possible because of it.

Project 2: Reverse Engineered Object (Week 1: Select)

이미지
 The second project we'll be working on is to reverse engineered object. To provide more information about the engineered object, it is a mechanical object that is complex or multiple parts and inherently made up of several components and assembled. Additionally, it should contain moving parts that interact with each other. This week, I will select few items and take a look at their parts and decide whether they are adequate for this project. After selecting an object among them, I will measure this object as precise as possible using caliper and re-build this each part of this object as 3D file using Rhino and eventually assemble them into a holistic piece. In this post, I am taking a closer look to figure out the objects I chose will be adequate for this project. I selected 3 items that are a ball point pen, a stapler, and a circle cutter. The reasons why I chose them are as follow: They are mechanical objects that are made up with some parts that interact each other. And their s

MILESTONE PROJECT 1: Stacked Slices Model

이미지
 For this week's project, I thought with the slices, I can probably make cylinder type light shade. Below are the inspirations. The second, fourth and fifth one shows somewhat continuous changes on each pieces, so I thought I can make a extruded surface (think of something like a carpet, with uneven surface) and let its one side serve as outside and the other side as inside of the figure, slice it and place it along the base shape of the cylinder.   I was drawing a free line, which will be the starting point of the uneven side of the surface. However, the line I drew really didn't reflect the shape I am imagining, so, I looked up some videos again.

ALGORITHMIC SURFACE MODELLING + ANIMATION

이미지
  This week, we are assigned to use algorithmic surface modeling, using surface morph, brep, divide domain square and extra. Process While finding tile examples, I found this peacock feather pattern and built line work based on it. And I made a brep, using a star shape with 16 lines, that are rounded. I used "loft" to make shape, and gave a bit of twist.  And found out that my surface morph is not happy with something. So, I tried to give bit of volume to my line work, and couldn't satisfy it. I tried to fix problems, now my divide domain square was not happy either. I thought maybe it is because of the twisted shape and made another brep, with no twist, and finally it was happy. I came back to the surface morph's problem and check what is bothering it. It seemed that my  reference line work being flat is causing the problem. I thought my instructor showcased making pattern with line work, however it didn't work with my line work. At first, I tried to pipe the lin
