Objects

  This week surface morph animation and some extra stuff.  Starting out with a divided curve I was able to use it determine points for circles and then using said circles to loft a structure. I then utilized the random numbers to offset the radius for each section in the loft and by utilizing "replace item" I was able to move a circle around the geometry. To show this variating animation without changing the seed values in the random numbers node. Bonus: Sending Grasshopper data via OSC/UPD to other programs I really wanted to use the program in conjunction with my main creative tools just to give me more reasoning to use grass hopper. You can utilize geometry in grass hopper and use them on other programs like MAX msp and Touch Designer for live visual effects or any other use cases. But as a caution try to re-mesh the models or simplify,  because grasshopper uses a lot of data and sending them live can cause it to crash if the models are too complicated.  Geometry ...

  This week in my Object design class, we were able to finalize out designs for laser cutting slices. My penguin model has gone through a couple of design adjustments mostly to have a cleaner and readable structure. simplifying the model makes it easier to distinguish, spherical curves on the original brep reference doesn't seem to provide appealing slices so I decided to go with a more geometric form. Once processed through grass hopper I didn't have a need to include wings because the tapered form still translates to something that appears like a wing.   On the left are the initial slices, the right is the cleaner side decided to mirror to create a more readable model. Above is the layout for laser cutting, I ended up layering the cut-outs manually because the grid method shown in last weeks class was quite troublesome. I just couldn't figure out how to pull of the grid placement on vector direction and didn't want to spend too much time confusing myself. (The penguin...

         My current sliced model for this weeks blogpost. I wanted to test modelling an object in Rhino first and using the mesh as the starting point for the contour slices in grass hopper. I ended up experimenting on different extrusion depths and the vector direction for the slices.  Modularity of grasshopper allows for rapid iteration and gives me a couple of choices to pick from. I decided on the vector slices along the y-axis which gave me a very simplified version of the bird but still recognizable.  Rough model doesn't need to be detailed because the contour slices simplifies everything else.

For the Milestone Project I wanted to build a small sound installation imitating critical habitats, to reinforce awareness about climate change and for viewers to have a sense of eco-responsibility. Entitled "Invasive" it refers to the consequences of human developments and disturbances within natural environments such as pollution, improper land management and exhaustion of finite ecological resources.  This installation wants to re-create these habitats with the absence of natural fauna and recreating a fleeting memory of them through machines.  Invasive  is an Sound Installation consisting of multiple solenoids embedded in a small artificial marsh-like habitat programmed to mimic the sounds created by fauna such as Insects, Amphibians and Small Birds.  These solenoids have a clicking sound when powered and potentially(Atleast that is what I'm hoping) we can recreate the sounds by increasing the frequency of the clicks through PWM? Percussive sounds may also be cre...

  Simple Relay circuit made for Arduino to control a lamp with a photocell. It uses a simple digital pin out to send a signal to trigger the relay and power on the lamp. Its similar to the blink setup code but instead of a small LED you are controlling another object with a larger voltage. 

  This week we had the chance to use animation functions in Grasshopper, it can be accessed by utilizing the slider nodes and mapping the values for frames you wish to record. I think its a very unique method you can access to add some motion control models.  To animate the balls in the structure I first subdivided curves in areas I wanted it to pivot and using the lists of points created by the divide node I was able to select where the ball cans track too. Similar to making objects track into a specific path.  I wanted to design a scene inspired by M.C. Eschers surrealist drawings of endless balconies and mazes. I was hoping I could animate each ball independently with remaped values to control speed and have variance. But for some reason whenever I select multiple curves to subdivide and install the balls, it produces another copy that I wasn't able to fix/trouble shoot. The program feels like a huge grind to learn but Im happy to put some effort or at least attempt to...

  In the first week of 310 class we got introduced into grasshopper a section of rhino that allows algorithmic modelling. It was a lot to process but it was interesting to see the back-end of the program and how you can patch alternative ways of modelling.  Grasshoppers UI is full on node based programming, where each parameter for a node can become modular. As seen above,  you can control multiple curves and adjust subdivisions in real time. It allows more control that manually rendering a model to which you have to commit to the final output. It does make it less painstaking to create complicated models such as organic curves or complex arrays. simple pots while I'm learning this new section. I may take it a little EXTRA simple the first couple weeks before going into more ambitious designs. I do have experience with node based programming but its like learning another language on top of everything else. I do hope to see what I can come up with in the future while parti...
