Subject: "Very Fast Real-Time Ocean Wave Foam Rendering Using Halftoning" — a retro comic-book/screenprint style ocean wave crashing, rendered entirely in bold black-and-white halftone dot patterns of varying density to show foam dissolving into sea spray, with one dramatic curling wave crest in the center. Palette is high-contrast black, white, and a single spot color of vivid cyan for the deep water beneath the foam. The style should feel like a 1960s pop-art screen print or an old newsprint illustration of a stormy sea. No text, no logos. ### 18. Tool result: generate_image GENERATED IMAGE #VR5A9K URL: /images/VR5A9K Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Real-time Breaking Waves for Shallow Water Simulations" — a single dramatic overturning wave caught mid-break at a rocky shoreline, rendered half as a smooth glassy 2D height-field surface and half as a detailed foaming 3D curling tube, showing the transition between simulation and reality. Storm-lit color palette: bruised violet sky, slate-grey sea, brilliant white spray catching a shaft of golden light. The mood is powerful and cinematic, like classic surf photography merged with a technical render of fluid simulation particles. No text, no logos. ### 19. Assistant Picked a "real-time water rendering" cluster from the corpus and made cover art for each, riffing on what each paper is actually about: 1. **#WZMZGY** *Advected river textures* — flowing dye-like ribbons around rock obstacles, echoing the paper's texture-advection-around-obstacles method → image #ZLQF5Z 2. **#XDESU9** *Scalable real-time animation of rivers* — an open-world aerial river network with stream-function contour lines, matching its large-scale/interpolated-flow approach → image #ZW6XQL 3. **#PBM2TC** *Water surface wavelets* — concentric wave-packet rings like a wavelet-transform diagram, reflecting its frequency-domain wave amplitude theory → image #8UCNGE 4. **#869NHK** *Very Fast Real-Time Ocean Wave Foam Rendering Using Halftoning* — literal halftone-dot foam, since the paper's whole trick is a dither/halftone mask for foam dissipation → image #Y5VJDK 5. **#8SERGP** *Real-time Breaking Waves for Shallow Water Simulations* — a wave split between smooth 2D height-field and detailed curling 3D overturn, mirroring its hybrid 2D+wave-patch technique → image #VR5A9K None are attached as document covers yet — say the word and I'll set any of them as `cover_image_id` on their respective documents via `update_document_metadata`. ### 20.

Composition is playful, graphic, and unmistakably video-game in style. No text, no logos. ### 102. Tool result: generate_image GENERATED IMAGE #HPGBZ4 URL: /images/HPGBZ4 Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Explainable AI for Designers: A Human-Centered Perspective on Mixed-Initiative Co-Creation" — a human game designer's hand sketching a level on a glowing tablet, while a translucent AI figure made of interconnected glowing nodes reaches in to collaboratively add and explain its own suggested elements, with a soft beam of light connecting human intention to machine reasoning. Palette: warm human skin tones and paper against a cool blue-violet AI glow. Composition is intimate, collaborative, and hopeful, like editorial illustration about human-AI creativity. No text, no logos. ### 103. Tool result: generate_image GENERATED IMAGE #F8LKSR URL: /images/F8LKSR Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Extracting Physics from Blended Platformer Game Levels" — two distinct retro platformer game worlds (one a green pipe-and-brick Mario-like world, one a grey sci-fi corridor world) visually melting and blending into each other in the center of the frame, with ghostly physics vectors (gravity arrows, jump arcs) overlaid and warping as the two rule-sets interpolate. Palette: warm nostalgic greens and reds on one side, cool metallic blues on the other, merging in a glitchy gradient seam down the middle. Composition is playful yet uncanny, like a glitch-art game mashup. No text, no logos. ### 104. Tool result: generate_image GENERATED IMAGE #MP5BHT URL: /images/MP5BHT Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Harmony-Seeking Computations: A Science of Non-Classical Dynamics" — a poetic collage-style composition uniting several small vignettes in one continuous flowing scene: an embryo dividing, a flock of geese in V-formation, a bench built around a tree, hayricks in a field, and a single Matisse-like brushstroke, all connected by the same glowing golden spiral of "wholeness" passing through each, suggesting one universal generative process. Palette: warm earthy naturalist tones with a luminous golden connecting thread. Composition is dreamlike, organic, and philosophical, like an illustrated scientific parable. No text, no logos. ### 105. Tool result: generate_image GENERATED IMAGE #JQ8QH3 URL: /images/JQ8QH3 Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Procedural Content Generation through Quality Diversity" — a vast luminous archive shelf or grid-map filled with dozens of small distinct generated game objects — spaceships, weapons, dungeons, creatures — each glowing a slightly different hue to represent its unique "niche" in a diversity map, with a few objects highlighted brighter as high-quality standouts. Palette: deep space-black background with a rainbow scatter of jewel-toned object icons arranged like a color-coded archive. Composition is playful, abundant, and collector's-cabinet-like. No text, no logos. ### 106. Tool result: generate_image GENERATED IMAGE #G88J4V URL: /images/G88J4V Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Real-time Rendering of Enhanced Shallow Water Fluid Simulations" — a shallow tide pool at dusk where photon-based caustic light patterns dance in intricate glowing lattices on the sandy bottom, refracted and reflected through the rippling water surface above, with screen-space reflections of an orange sunset visible on the surface. Palette: warm amber sunset light, cool turquoise shallow water, dazzling white-gold caustic networks. Composition is luminous, serene, and photorealistic with a touch of abstraction. No text, no logos. ### 107. Tool result: generate_image GENERATED IMAGE #4TS5S8 URL: /images/4TS5S8 Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Real-time Rendering of River Networks" — an elegant river bend rendered as a glowing Bézier curve skeleton with visible control points and tangent handles, the mathematical curve seamlessly transforming into a photorealistic flowing river surface with streaming normal-mapped ripples following its arc length. Palette: crisp technical blue-white curve diagram dissolving into natural glassy green-blue river water. Composition is a clean half-diagram, half-photograph split, elegant and precise. No text, no logos. ### 108. Tool result: generate_image GENERATED IMAGE #4MJBXR URL: /images/4MJBXR Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Runtime Evaluation of Procedural Content Generation in an Endless Runner Game Using Autonomous Agents" — a fast-paced stylized endless-runner game world stretching to the horizon, tiles and obstacles materializing procedurally ahead of a small running character, while two translucent ghost-agents (one flying, one on the ground) race ahead scanning and testing the generated terrain with visible raycasts and a small crash-report marker where a gap failed. Palette: vibrant candy-colored game-art tones (coral, teal, lemon yellow) with cool cyan scanning-ray overlays. Composition is energetic, playful, and slightly technical. No text, no logos. ### 109. Tool result: generate_image GENERATED IMAGE #BTFJ8Z URL: /images/BTFJ8Z Model: gpt-image-2 Prompt: Album cover art, square format. Subject: "Towards Friendly Mixed Initiative Procedural Content Generation: Three Pillars of Industry" — a warm, welcoming illustration of a human designer and a friendly, non-threatening AI assistant (rendered as a soft glowing helper shape, not a cold robot) sitting side by side at a drafting table, co-designing a dungeon level together, with three glowing pillars in the background labeled only by simple icons for control, creativity, and workflow. Palette: warm studio lighting, cozy wood-tone table, soft teal glow from the AI collaborator. Composition is friendly, human-centered, and optimistic, like a modern tech-industry editorial illustration. No text, no logos. ### 110.

One image (the PCGML cover) got moderation-blocked on the first pass for referencing "Mario-like" — regenerated with a fully generic retro platformer instead (#85E66Z) and that's now set too. The whole library has cover art.
