# World Within: Colored Scanning Electron Microscopes (SEM) SEM scans of various plant seeds colorized

Colored Electron Microscope Scans are amazing! These were photos I would stare at in the science textbook as a kid. Recently, I came across one of these Scanning Electron Microscope (SEM) scans at the Miller Gallery in the exhibit World Within. Scientifically and algorithmically these scans are generated by using a beam of an electron to scan the surface of the object. In comparison to a beam of visible photons, the electrons’ wavelength is 10,000 times shorter thereby enabling higher precision in vision. The SEM has an electron optical lens which works similarly to a light camera lens to capture the reflected electrons, and afterward through some image processing algorithm, a SEM image emerges. While SEM, allows us to see the world at a whole different level, it only allows us to see that world in black and white because of the nature of electrons’ micro wavelength. Without the artist’s sensibility, these scans would just be mere black and white photos. Today, the common practice of coloring a SEM photo is still via Photoshop or other feature detection software.

Using a Lindenmayer system, each plant grows towards the sun. Every plant starts with a seed, and randomly generates branches to reduce its distance towards the sun at (width/2, -height*2) for a maximum recursion depth of 7. A number of sub-branches (children) each branch (node) generates is random between 1-4.

For my design, I wanted something simple and to the point. So as I was looking for inspiration, I noticed a lot of wall designs with stripes and such. To add a bit more, I added in flowers into the design as well.

I wanted to make a cute wallpaper with umbrellas to signify my deep seated hope that maybe Pittsburgh will start cooling down for Fall and stop cooking us alive at 80 – 90 degrees. Let the rain fall.

Coding the loop was pretty simple, coding the shapes is still the most finicky part. However, using graph paper to sketch out things first helps. ## ikrsek-Looking Outwards-05

This week for the topic of Computer Graphics, one of the most compelling artists that utilizes CG for their work would be Hayden Zezula. He works primarily as an animator doing designs and such for brands like Adidas, HBO, or Adultswim – and mucho of his portfolio work comes in the form of gifs or video. Overall, the reason why I chose him is because of his experimentation with representing texture and form in a 3D style on a 2d screen. His work is extremely visually captivating, both because of the bizarre content that is displayed and the sheer technical ability he diplays. There is not a lot to be said for his work that isn’t said by the work itself, and unfortunately I can only post photos of it since gifs don’t seem to play when you post them here, so here are a few screenshots – though I highly recommend you visit his website or instagram and view the work as it is meant to be seen.

Alien Bonsais by Chaotic Atmospheres

http://chaoticatmospheres.com/alien-bonsais

What I admire about this project are the organic structures, shapes, etc. created to as an inorganic iteration of a bonsai tree. In a way, Chaotic Atmospheres is creating a sculpture on the bonsai tree digitally which would be too difficult to manifest physically on a real, living organism. Thus, that makes the shapes created in relation to the tree a true “alien” visual. What I know of the algorithms used for this project is that the artist used a 3D software called Substance Designers which he embedded onto his own digital trees to create the alien texturing of his bonsais. His artistic sensibilities were utilized in the organization of constructing the digital trees and altering the tones, color, shapes, sizing, movement, etc. of the product so that the image was cohesive and aesthetically intriguing.  ## mjeong1-05-Wallpaper-SectionA

For this project, I started with two different types of tile, one with half watermelon and the other with eaten watermelon.  And I created pattern with two tiles with yellow background with seed pattern. # Green Void / LAVA “Green Void” by Architect LAVA in Sydney,Austrailia The installation Green Void is a digitally patterned product which is located in the main interior atrium of the Customs House. The design process started with 3D computer modelling, and fabricated under a process of computer controlled(CNC) material cutting. The computer model is exclusively based on the simulation of  complex evolving system using certain geometric algorithm, which feeds directly into a production through manufacturing. The design shows a new way of digital workflow by enabling shape of the product to be generated through computational workflow in a extremely shot time.

What I admire about this project is how rendered 3D graphic image looks similar to final installation and how the 3d image can inform people about the final work even before the fabrication. It might be impossible to have this indirect experience of the space without the computer generated image. Especially in the field of architecture, design through computer graphic can be a core of design process since it is much easier to explain your project through visual representation and also you can have feedback in a relatively short time.
