OBDF 310: Animation

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 learn it to the best of my ability.

OBDF310 Milestone Project 1: Stacked Slices

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.

Algorithmic Surface Modelling

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 used to C

OBDF 310 Milestone: Stacked Slices Laser cut Final

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
