For this week I am talking about the YouTuber Answer in Progress, and her video “the science behind lofi music”. Lofi hip hop music has become popular in the late 2010s and early 2020s as background music for studying and gaming amongst Millennials and Gen Z. Answer in Progress sought to write an AI that could randomly produce lofi music. She gave the program a bunch of different drum and instrumental audio files and background noise, told it what frequencies and RPMs to play at that most lofi music plays at, and has the AI learn what notes should come after what other notes. Then her code should be able to produce a lofi song on its own. There are a few errors, including one song that just plays the same note over and over again, so the program does not produce a very sonically pleasing songs. It lacks an ear for what makes some notes and chords more pleasing than others that humans have, but its pretty impressive for randomly generated music with no human help.

}I loved this project. I had a really great time breaking down the steps of drawing into individual functions to make the process easier. Additionally, it was very satisfying to get the loops working properly because I had to iterate on that a few times. The patterns would either be too far apart or on top of one another.

For 3D computer art, I looked at the artist known as Chaotic Atmospheres from Switzerland. They have made digital art since 2012. As their name implies, Chaotic Atmospheres makes atmospheres and landscapes but alters them in a surrealist way. Specifically, for their project “Shapes in Nature”, their environments will often be large in scale, have exaggerated features of the environment being depicted, and some large geometric shape in the middle that is reflective. The reason I find their work so impressive is their attention to detail. They make both art from scratch and art made from imported textures, both of which are laborious tasks, either writing code to create the images or writing code to take the textures and create realistic environments out of them. Additionally, creating the reflection must be difficult, whether it be algorithmic like ray tracing or hard-coded into the work.

The video “Sound Machines” on the YouTube channel MediaArtTube demonstrates a machine that uses light recognition to play sound. The machine has three sensors and takes in visual information from vinyl record sized discs with patters engraved. The three discs have different types of patterns which the sensors read. The first reads color, with the disk having red, yellow, and blue lines on a white disc, depending on where the sensor is located up or down the radius changes the sequence of colors, therefore changing the sound. The second disc reads either black or white, with 3 patterns made using a black disc hollowed out. When the sensor detects black is plays a noise. The final disk is split into thirds, where white becomes more and more grey. The sensor reads the grey scale and increases the volume the grayer the image gets.

I had difficulty with this project. I had a hard time coming up with something to draw. Once I had an idea I really enjoyed coming up with ways as to how I could incorporate dynamic elements into it. One thing, in particular, I am proud of is figuring out that the map function can work backwards, with the higher value being the start point and the lower value being the stop point, which allows you to invert the value of a variable in a sense.

I looked at Torolf Saurmann’s Moebius Ring. I chose this piece because I find its intricacy really beautiful. The strange spiral the ring inverts itself on is facilitating to look at and the mesh design it has increases that enjoyment. Because of the mesh design, the ring is somewhat see through. This further complicates of the spiral inverts itself and requires the viewer to focus to understand it. I find it really fun and enjoy the design. The algorithm that generated this work was likely very versatile and I think that comes from the mesh design. Not only does the mesh save material, it also puts the entire project into component parts that were likely much easier to code into larger designs. The Ring is also able to stand up on its own and I wonder if that is a coincidence or something the algorithm makes sure can happen. Saurmann as an artist really likes round and circular shapes, which one can see in his other work. In this piece he doubles down on that by basing his design on a Mobius Strip, a circle that inverts and doubles back on itself. This piece does that multiple times, to the point where its hard to tell where one inversion stops another the next begins.

LookingOutwards-02 Dave Bollinger
I really loved Dave Bollinger’s collection of glass like geometric pieces. The pieces look like abstract stained glass, with really natural looking curves and divisions that look like it was shattered. I really like this randomness as it is satisfying how different each work looks while still being part of the same collection, and demonstrates a robust algorithm for randomization with many possible ways the “shards” could have been created. Also, the use of color is really amazing, the way some of the colors fade out looks the same way worn stained glass fades over time. It feels as if the sun is behind the patterns shining through. I admire this use of color because it shows dedication to recreating the effect of real glass and it must have been a complex effect to code. Most of these pieces focus on one color but a few of them have many colors which demonstrates that the algorithm must have been versatile in the way it filled in the shards.

}I had a lot of fun with this project. It was interesting trying to come up with more and more ways to make the face different. One of my early troubles was a problem with my eye colors. I was using “if(eyeColor == x)…” and eyeColor = “random(1,10)” but most clicks would end with no irises at all. I then realized the problem was that random() gives a floating point number and I was asking for a specific integer, so the odds of getting one were super low, so I changed the line to “floor(random(1,10))” which thankfully fixed it.
