Liquid System

This is a really cool liquid visualization that I came across awhile ago. Moving the mouse around lets you navigate through these suspended bubbles. It allows you to zoom in and out as well. Adding a z dimension to processing is something I would like to eventually get into and understand, I’m sure its actually relatively simple. This particular example almost feels like frozen beer or something.

Virtual Urbanity

Virtual Urbanity is a thesis project that was designed by Rafail Bakolas at the Bartlett School of Graduate Studies. It was programmed using the processing language. It is a parametric simulation engine which models a vast and diverse amount of 3D urban configurations. It is based on a Lindenmayer system which I think works like fractals. Or even like Processing on some level. So there would be a set of rules (if this, then that) which take a string of input and produces an output that grows exponentially. This project defines the topology, the geometry, the width, the length, the density and the spatial significance of the streets. Conceptually the aim is to draw relationships between the creation of a realistic urban setting in the physical world to the abstract imaginary environment of the virtual world.

 

Here is where you can get a pdf of the thesis. It’s pretty interesting stuff.

Cool Visualization

Hey guys,

I ran across this project and really like its functionality. I’m trying to mess with the source code to develop something similar myself but maybe with different shapes and reactions. We will see how it goes. Anyway its a really cool simple idea that I could see growing and developing into something interesting. As it stands now it functions very well and is fun to play with. I keep wanting to combine applets like this with music to create a music visualization that is possible interactive in some way. I will try to embed this applet, hope it works, so you guys can see it. Otherwise just copy the source code into processing and it will run. All credits to the author of the code, Daniel Winkler.

If this embed doesn’t work, just see this link here http://www.openprocessing.org/visuals/?visualID=3148

Where Architecture is heading…

I wanted to bring up a point to something which was said in class by Professor Kearns. The idea that 3d modeling will be used to check that a building is to code. This is not unrealistic  by any means and I believe it is coming. The question I have is what is an architect at this point? Architects will seem to become more computer programmers and just as good if not better as a designer. Below is an article on how competitive the field is becoming and how employment/opportunities are decreasing tremendously. One thing is for sure the role of an architect will change and what we are being trained to do now may not matter much in twenty-five years.

Animating 3d Models

Referring back to the discussion on 3d modeling. I have come across some great programs add/ons to animate a 3d model. One of them I have been introduced to from my landscape internship, it is called Viz Terra. The nice thing is that water can be animated to appear as shimmering with slight movement. There also is Vray. Taking 3-d modeling to the next stage by animating is great, especially if trying to sell the idea to potential buyers, it just adds the next step of reality.
