Rays curve away from this layer, back towards the surface of the water, revealing the mirage of a ship that is just behind the horizon. https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/21dbe2e8-0185-44d1-9ae7-43d56bee1f10/inferior_mirage_inf.jpg Research Portolio - Dissertation Research: Curved Ray Rendering An inferior mirage caused by warm air close to the water's surface. This causes a vertical visual stretching of the ship, and a complete reflection of objects far behind it. https://www.reaganburke.com/research-portolio/clouds monthly 0.5 2025-02-01 https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/405c0e98-94d2-4b4e-b24e-2f44e3f56310/MegaDenseBunny_0280.png Research Portolio - Cloud Rendering with Ray Marching Level Sets convert watertight polygonal models into signed distance fields, which can then be modulated with noise: a staple effect in VFX. https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/e89dde07-5c5f-4b7f-be7f-80fc3c8a1bc5/Cloud.png Research Portolio - Cloud Rendering with Ray Marching Pyroclastic spheres like this one are commonly used to create thick clouds with hard boundaries, much like you might see when a volcano erupts. https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/34195740-41c2-467e-bc7e-a2775ad7c3fd/Wisp2.png Research Portolio - Cloud Rendering with Ray Marching This is a wisp.

Low noise frequency leads to softer features. Higher FJump values creates spikes. https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/6bfe6e4d-75dd-4e8d-bc42-f19313002ab9/Stamp.png Research Portolio - Cloud Rendering with Ray Marching This is noise with a falloff radius stamped directly into a grid. This type of noise is good for creating clouds of arbitrary size and shape with soft boundaries. https://www.reaganburke.com/research-portolio/particles monthly 0.5 2025-02-01 https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/993d1916-cdc9-4c28-92a6-156e1bd44e73/Cloth.png Research Portolio - Physically-Based Animation Cloth is simulated with strut forces between discrete points along the surface. 3 corners here are pinned.

Additionally, subtle particle effects abound in Yolo Solo. From the birds in the sky, to the dust on your shoes, to the prominent *SPLAT* when you land hard. This game was made with love. https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/da8e1a8b-eb21-41bb-9e3e-6d4954398ad1/Particles_1.gif Research Portolio - Physically-Based Animation This GIF shows a variety of particle forces including collisions, flocking behavior, and rigid body dynamics. The rigid body behavior briefly shown here was further developed to drive ship buoyancy simulations shown above. https://www.reaganburke.com/other daily 0.75 2025-05-09 https://www.reaganburke.com/other/project-four-l3zw3-dwkba monthly 0.5 2025-04-11 https://www.reaganburke.com/other/vulkan monthly 0.5 2025-04-11 https://www.reaganburke.com/other/painting monthly 0.5 2025-04-12 https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/655b0c0a-9986-4a3b-937c-a22a4fcd3f05/Lenny.png Projects - Painting Colorado Comet (2024): Acrylic on Canvas Board https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/155aa2f8-a6fb-49fb-bacd-c3bbcca69c82/Chip.png Projects - Painting NFL Quarterback Club (2020): Gouache on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/8d0d974b-907f-4922-8ef2-b2d42e97d222/Egg.png Projects - Painting Eggs (2020): Gouache on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/e073673a-4858-406e-8912-b1282661907a/FourthWall.png Projects - Painting Fourth Wall (2024): Watercolor on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/2b90296a-c529-4c79-ba77-1c41b5d31ee3/Levy.png Projects - Painting The Levee During a Storm (2024): Watercolor on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/f350f31b-ea6c-40dd-8574-d51e3f8e34ac/Oak.png Projects - Painting Cold Gumbo #16 (2019): Watercolor on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/033e7313-b44f-4bc3-889e-c8a70ba4b2a5/Speaker.png Projects - Painting Chip (2020): Gouache on Paper https://images.squarespace-cdn.com/content/v1/679cece5530a9528d5a59fcf/f49f6c4f-2fb8-4739-b5bb-63ef94c6facb/Spoon.png Projects - Painting Self Portrait with Spoon (2020): Gouache on Paper
