In images, 1 cycle of a sinusoid manifests as a white-black-white gradient. The top most sinusoid is slow (i.e. frequency), and is only able to complete 10% of the white-black-white cycle over the width of the image. The second sinusoid completes exactly 1 white-black-white cycle over the width of the image. The lower 3 sinusoids are much faster (i.e. high frequency) and are able to cover 10, 100, and 1000 white-black-white cycles over the width of the image. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/8d9225cc-c12d-423e-846f-fe3b384581d7/P5032_BlobLODStudy1_0018_20211127233953.jpg Notebook - Level of Detail Study - Figure 4 This scribble’s stroke width is set relative to the diameter of the scribble.

Over 50% of the image is empty at this scale, and perceptual variety is very, very high (i.e. if 100 circle packing grids at this scale, all 100 appear very different from each other). https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/da8e0954-4269-4cd4-8424-1da6ebcfd85f/P522006_CirclePack_WIP_20220314131007+-+0.01x+shortSide.jpg Notebook - Circle Packing Study - Figure 4a minDiam = 0.01x shortSide This min diameter size ratio will serve as a baseline for comparison.

There are many large voids within the grid. Perceptual variety increases substantially at this scale. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/d61b50ef-93af-4b70-9354-1953fcbb7036/P522006_CirclePack_WIP_20220314130234+-+1x+shortSide.jpg Notebook - Circle Packing Study - Figure 3b maxDiam = 1x shortSide As the max diameter increases, the amount of negative space increases. If the diameters of each circle are analyzed, they will likely follow a power law distribution. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/82ae06c9-b44e-4558-8395-4c72ee0df4a6/P522006_CirclePack_WIP_20220314130111+-+0.5x+shortSide.jpg Notebook - Circle Packing Study - Figure 3a maxDiam = 0.5x shortSide This max diameter size ratio will serve as a baseline for comparison.

This image for example, could look like a stack of things piled over a hill. Also note that perceptual variety is very high in at these max diameter size ratios. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/7e6c0eee-53e6-46f2-ba28-e5e356b9913b/P522006_CirclePack_WIP_20220314130848+-+0.001x+shortSide.jpg Notebook - Circle Packing Study - Figure 4b minDiam = 0.001x shortSide This image uses a min diameter ration that is 10x smaller than Figure 4a, which yielded a far tigher packing density. There is nearly no negative space between neighboring circles. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/c85a7521-3128-45a1-935c-743ebdbeab23/P522006_CirclePack_WIP_20220314125148+-+2x+minDiam.jpg Notebook - Circle Packing Study - Figure 2a maxDiam = 2x minDiam On a relative basis, there is nearly no difference in size between the smallest and largest circles in the grid. When the circles are small, this yields a very uniform look. There is very little perceptual variety at this scale (i.e. if 100 circle packing grids at this scale, all 100 appear nearly identical to each other). https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/b4fc920b-367c-4079-b507-ae7db99657d8/P522006_CirclePack_WIP_20220314125407+-+10x+minDiam.jpg Notebook - Circle Packing Study - Figure 2b maxDiam = 10x minDiam At this min-max diameter ratio, the larger circles start to look visually different, and voids start appearing in contrast to the denser regions of the grid. https://www.ericdiep.xyz/home daily 0.75 2022-07-03 https://www.ericdiep.xyz/origin-story daily 0.75 2022-11-16 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/f36c9687-6244-49a2-84b7-aee0deea912f/Eric+Diep+Sig+-+Sm.png https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/99b7e03d-ed8d-4958-a148-a8fc2111c1a8/Origin+Story+1+-+2000px.jpg https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/d3f24112-f07c-4eb9-8ecd-7019aecdf0b3/Origin+Story+2+-+2000px.jpg https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/db58552d-9019-40e2-aa49-e7bddd20b31b/Origin+Story+3+-+2000px.jpg https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/730ac06e-14ae-449d-8d57-efe96a6298ff/Origin+Story+4+-+2000px.jpg https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/c1ba60ca-ca6f-4cdc-956c-488aeb068ee2/Origin+Story+5+-+2000px.png https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/b36de6d0-105b-43a0-8da6-fe29377f7ceb/Origin+Story+1+-+2000px.jpg Origin Story Part #1 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/d3f24112-f07c-4eb9-8ecd-7019aecdf0b3/Origin+Story+2+-+2000px.jpg Origin Story Part #2 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/db58552d-9019-40e2-aa49-e7bddd20b31b/Origin+Story+3+-+2000px.jpg Origin Story Part #3 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/730ac06e-14ae-449d-8d57-efe96a6298ff/Origin+Story+4+-+2000px.jpg Origin Story Part #4 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/c1ba60ca-ca6f-4cdc-956c-488aeb068ee2/Origin+Story+5+-+2000px.png Origin Story Part #5 https://www.ericdiep.xyz/collection daily 1.0 2022-11-16 https://www.ericdiep.xyz/opus-1 daily 0.75 2022-11-16 https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/8547c11b-5b54-452b-b7c0-8161e28421b5/P522041_179064513734_withMargin+-+lg.jpg Opus 1 - Make it stand out Opus 1, The Fave https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/a3a2c706-6fbe-4d58-ac9d-6be2bbe05554/P522041_Grid_withMargin+-+lg.jpg Opus 1 - Make it stand out Opus 1, The Grid https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/8547c11b-5b54-452b-b7c0-8161e28421b5/P522041_179064513734_withMargin+-+lg.jpg Opus 1 - Make it stand out Opus 1, The Fave - The final curated output of the Opus 1 algorithm, amongst 1000 total outputs. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/a3a2c706-6fbe-4d58-ac9d-6be2bbe05554/P522041_Grid_withMargin+-+lg.jpg Opus 1 - Make it stand out Opus 1, The Grid - The next top 16 curated outputs from the Opus 1 algorithm. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/9a5ddd03-29a3-4430-bb4c-fdd4cb74c74d/Opus+1+-+Layer+3.jpg Opus 1 - Make it stand out The rendering of the brushstroke happens in 5 steps: (1) make the path, (2) calculate normal angles at each point to generate multiple parallel paths, (3 & 4) draw each parallel path using variable stroke weight and gray values, and (5) add ink splatter effect. https://images.squarespace-cdn.com/content/v1/6153e8b3a87a394f7bbcafa5/2b1572bb-c3a8-46b1-9c5e-2e0702c36d7d/Opus+1+-+Layer+1.jpg Opus 1 - Make it stand out The isometric random walk can be parameterized as a 3-variable system: glyph size [# of steps], probability of changing directions, and number steps.
