🌍 Tab 1 — Prehistoric World A living, animated prehistoric scene that changes completely with each geological period. Selecting Triassic, Jurassic, Cretaceous, or K-Pg Event transforms the sky colour, vegetation, volcano activity, and dinosaur species on screen. Theropods (bipedal), sauropods (long-necked), and pterosaurs move and bob across the landscape with walking animation. A time-of-day slider cycles through dawn, daylight, dusk, and night — stars appear at night and the sun arcs across the sky by day. Weather modes (Clear, Cloudy, Rain, Storm) add rain streaks and cloud cover. Volcanic ash particles drift from the background volcano in the Triassic and Jurassic scenes. Global temperature, oxygen level, and CO₂ concentration for each era are shown live in the side panel. Hit ☄️ Impact! to jump straight to the extinction event. 📊 Tab 2 — Timeline An interactive geological timeline spanning the full Mesozoic — 252 Ma to 66 Ma. Drag the time cursor to travel through the Triassic, Jurassic, and Cretaceous, and watch the side panel update with the period name, estimated global temperature, and known species count. Seventeen major events are plotted as vertical markers: mass extinctions sit at full height, species events stagger between short and medium tiers so labels never overlap. Each label sits on a dark pill background for legibility. A temperature curve overlays the timeline axis. Period bands (Triassic / Jurassic / Cretaceous) are colour-coded across the full canvas. 🦖 Tab 3 — Species Explorer Nine key species are displayed in a 3×3 animated grid — T. rex, Brachiosaurus, Triceratops, Stegosaurus, Velociraptor, Spinosaurus, Ankylosaurus, Iguanodon, and Archaeopteryx. Each cell shows the dinosaur's walking or swaying animation, its period badge, body length, and weight. Clicking any cell loads its full profile in the side panel: scientific name, geological age, diet, bite force or other distinguishing stats, and a paragraph on its biology and recent fossil discoveries. A clade filter (Theropods, Sauropods, Ceratopsians, Ankylosaurs, Ornithopods) narrows the grid to the selected group. 💥 Tab 4 — K-Pg Extinction A six-phase simulation of the Chicxulub asteroid impact, 66 million years ago. Before — a peaceful Cretaceous scene with living dinosaurs. Entry — the fireball streaks across the sky at the set velocity. Impact — expanding shockwave rings, ejecta debris fountaining outward, blinding flash. Firestorm — global fires blanketing the surface, smoke columns rising. Winter — ash snowfall, temperature plunge, bare dead trees, total darkness. Recovery — vegetation slowly returns, early mammals appear, recovery percentage climbs with the years-after-impact slider. Asteroid diameter (5–20 km) and velocity (10–40 km/s) are adjustable — energy output, global temperature, species extinction percentage, and recovery time all recalculate in real time. 🧬 Tab 5 — Evolution Tree A radial phylogenetic tree of 19 dinosaur clades, from the root Dinosauria node through the Saurischia / Ornithischia split, down to families like Tyrannosauridae, Dromaeosauridae, Titanosauria, and Avialae (birds). Each node glows in its clade colour and pulses gently. Hover any node to see its name and first-appearance date in millions of years. Bézier curves connect parent and child clades. A red dashed line marks the K-Pg boundary at 66 Ma — only the Avialae branch crosses it, illustrating that birds are the sole surviving dinosaur lineage. A geological time scale runs along the bottom with Triassic, Jurassic, and Cretaceous colour bands.

Submarine Principles Visualizer 5 ⚓ Tab 1 — Buoyancy Archimedes' principle visualised as a live physics simulation. Buoyant force (F = ρgV) and gravitational weight are shown as opposing arrows, and the submarine actually rises or sinks in real time depending on how much ballast water is loaded. Adjustable parameters: submarine mass, seawater density, hull volume, and ballast fill percentage. A depth ruler on the right tracks the current position. 🌊 Tab 2 — Ballast Tanks A cutaway cross-section view of the submarine's interior. The two main ballast tanks (MBT — forward and aft) and two trim tanks are rendered with live water fill levels and animated surface ripples inside each tank. High-pressure air bottle charge is visualised as a pressure bar. Four quick-set presets: Surface, Neutral, Dive, and Emergency Blow. Pitch angle is calculated in real time from the trim tank imbalance. 🔧 Tab 3 — Dive & Ascent Set a target depth with the slider and the submarine dives or ascends to it using real physics — driven by hydroplane angle and ballast fill. Bow and stern dive plane angles are drawn directly on the canvas. Live readouts show hull stress level, a 400 m test-depth warning line, and the current dive/ascent rate in metres per minute. 🧭 Tab 4 — Navigation The submarine is steered in real time on a top-down chart view. Adjusting the rudder slider changes heading and leaves a visible wake trail; ocean current continuously deflects the track. A compass rose in the top-right corner shows the live heading. The INS panel displays heading, speed, distance travelled, and current depth. 📡 Tab 5 — Sonar & Systems Three sonar modes — Active, Passive, and Towed Array — are visualised on a radar-style scope. A rotating sweep line detects contacts within range and marks them with icons: surface ships, submarines, whales, and fish schools. A passive sonar waterfall spectrogram runs down the right side. Background noise, own-ship noise, and effective detection range are all calculated live. Life support system status — oxygen, fresh water, reactor output, and battery charge — is displayed in the side panel.

🌆 Tab 1 — Cityscape Drag the year slider from 2025 to 2100 and watch the city evolve in real time. Vertical gardens, solar panels, hyperloop tubes, drone corridors, and autonomous vehicles all coexist in a day/night cycle simulation. Four city styles: 🌿 Arcology (nature-integrated), ⚡ High-Tech (advanced tech), ☀️ Solarpunk (solar-powered), 🌊 Underwater (seabed city). Adjustable tech level, green coverage, population, and time of day. ⚡ Tab 2 — Energy Grid Manage a smart grid in real time by balancing four energy sources: solar, wind, fusion, and battery storage. Energy packets flow from generators to district consumers, visualised as a live node network. Four event modes: Normal / Peak Demand / Solar Storm / Grid Failure. Total generation, surplus or deficit, renewable share, and carbon intensity are all calculated live. 🚊 Tab 3 — Mobility Autonomous pods, drone taxis, and a hyperloop capsule operate simultaneously across a grid-based future city. Raising the AI optimisation level improves traffic flow and renders route prediction lines. A congestion slider lets you simulate gridlock scenarios. Live readouts show average trip time, active pod and drone counts, and transport carbon emissions (electric = 0 g/km). 🌿 Tab 4 — Eco Systems Adjust four ecological infrastructure types — vertical forests, algae bioreactors, urban farms, and wildlife corridors — and watch carbon capture, food self-sufficiency, biodiversity index, and air quality update live. Includes pollen, spore, and raindrop particle effects, bird flocking animation, and a rainfall-responsive rain overlay. 🤖 Tab 5 — AI & Data Brain The city's central AI neural network is visualised as a radial diagram. Eight domain AI agents — mobility, energy, security, health, ecology, climate, economy, and education — exchange live data packets with the central City Brain node. Four event modes: Normal Ops / Crisis Mode / Self-Upgrade / Cyber Attack. Adjustable AI capability level, sensor density, data throughput, quantum computing share, and privacy level.

🦠 Tab 1 — Natural Selection Organisms carry genes for speed, size, and camouflage as they move, forage for food, and evade predators. Each generation, survivors reproduce and mutations accumulate, shifting the population's average traits in real time. Four habitats to choose from — savanna, forest, arctic, and ocean — with adjustable predator count, mutation rate, selection pressure, and food abundance. Right-click any organism to remove it, simulating targeted predation. Hit ☠ Mass Extinction to trigger a population collapse event. A live average-fitness chart updates with every generation. 🧬 Tab 2 — DNA & Mutation Visualises DNA double-helix replication at the base-pair level (A, T, G, C). A replication fork advances along the strand, and you can choose which type of mutation to observe: point mutation (single base substitution), insertion, deletion, or crossover. Mutated positions are highlighted in pink. GC content and sequence divergence from the original strand are calculated live. 🌿 Tab 3 — Ecosystem A full three-trophic-level food chain — plants → herbivores → carnivores — simulated as a living ecosystem. All three species evolve simultaneously, and Lotka–Volterra population oscillation cycles emerge naturally without any scripting. A real-time population graph at the bottom of the side panel tracks the cycles (green = plants, yellow = herbivores, red = carnivores). Plant regrowth rate, starting herbivore and carnivore counts, and mutation rate are all adjustable. 🔬 Tab 4 — Speciation A single population is split into two groups — A and B — by a geographic barrier (mountain range, ocean channel, or desert). Each group evolves independently under different selection pressures, and their traits (visualised as colour) diverge over generations. Increasing barrier permeability allows gene flow between the two groups, slowing divergence. The genetic divergence bar at the top fills toward 100% as speciation nears completion. 📈 Tab 5 — Phylogeny A radial phylogenetic tree grows automatically every time a speciation event occurs from the common ancestor. Node colour represents genetic distance from the root — green for ancestral lineages, shifting through blue and purple to red for highly diverged species. Extinct lineages are marked with a grey cross. Branching rate, extinction rate, and mutation per branch are all adjustable. Hit ⚡ Adaptive Radiation to instantly trigger a burst of rapid speciation.

🌋 Tab 1 — Fault & Seismic Waves A real-time fault cross-section simulation. Click anywhere on the canvas to set a new epicentre — P-waves (yellow), S-waves (orange), and surface waves (red) immediately radiate outward as concentric rings at their respective speeds. The canvas shows the hypocenter, epicentre, fault line, and a geological cross-section (sediment, granite, lower crust). Ground shaking and soil debris particles spawn as intensity increases. Controls include fault type (strike-slip, reverse, normal), focal depth, and rock hardness. Hit ⚡ Trigger M8.0 to fire a large earthquake instantly. 🏙 Tab 2 — Building Damage Twelve different building types respond to shaking in real time — unreinforced masonry, pre- and post-modern reinforced concrete, timber frame, and modern seismically designed structures progress from vibration to cracking to collapse to rubble. Adjustable parameters: magnitude, soil type (bedrock / sand / soft clay / liquefiable), building code era (1950s to modern), distance from the fault, and shake intensity. A live seismograph waveform runs along the bottom. Collapse rate, heavy damage rate, estimated casualties, and undamaged percentage are all calculated live. 🗾 Tab 3 — Seismic Map A global seismic hazard map with 26 high-risk zones rendered as pulsing hotspots. Tectonic plate boundaries and 14 historical M7+ earthquake records are overlaid — including Tōhoku, Chile, Sumatra, Nepal, and Haiti. A four-tier hazard legend (Extreme / High / Moderate / Low) is shown at the bottom left. 🌊 Tab 4 — Tsunami A cross-section simulation of the full tsunami lifecycle: submarine earthquake → wave generation → shoaling → coastal inundation. The wave travels at ~800 km/h in deep water, then slows and dramatically steepens as it approaches shore — the shoaling effect. Coastal buildings flood and collapse, and the inundation zone advances inland. Adjustable parameters: magnitude, seafloor displacement, ocean depth, coastal slope, and wave speed. Real-time readouts show deep-water speed, runup height, estimated arrival time, and inundation distance. 📊 Tab 5 — Risk Analysis Earthquake risk is calculated as Hazard × Exposure × Vulnerability and displayed on a semicircular gauge dial for four cities: Tokyo, San Francisco, Istanbul, and Kathmandu. Factor bars show each component scored out of 10. A Custom mode lets you define any city profile and simulate its overall risk score and rating (Low / Moderate / High / Critical).

🧊 Tab 1 — Ice Loss Adjust the year slider (1850–2100) and warming scenario (+1–4°C) to watch glaciers melt in real time. As the year advances, the glacier shrinks, crevasses open up, icebergs calve from the front, and meltwater streams run down the surface — all physically simulated. A timeline bar at the bottom shows the current year position. Live readouts display remaining ice percentage, annual loss rate (Gt/yr), and sea level contribution. 🌊 Tab 2 — Sea Level Rise Adjust sea level rise (0–3 m) and storm surge sliders to flood the skylines of five cities — New York, Tokyo, Miami, Jakarta, and Dhaka. Building windows submerge as the water rises and a flood line marks the current level. Population at risk (millions), inundated land area (km²), and economic loss ($T) are all calculated live. 🌡 Tab 3 — Temperature Historical temperature anomaly data from 1850 to 2024 is displayed as a colour-coded bar chart — blue for cool years, red for warm ones. Four future pathways (1.5 / 2.0 / 3.0 / 4.5°C) are overlaid as projection lines extending to 2100. Background shading marks the 1.5°C Paris target, the dangerous zone, and the catastrophic zone. 🌍 Tab 4 — Global Impact The cascading consequences of glacier melt are visualised as an interactive network graph. Nine nodes — glaciers, sea level, freshwater, ice-albedo feedback, permafrost, ecosystems, migration, food security, and economy — are connected by animated flowing edges. Clicking a category button (💧 Freshwater / 🌾 Food / 🐻 Ecosystems / 👥 Human) highlights the relevant impact chain. ⏳ Tab 5 — Future Scenarios Remaining glacier ice from 2024 to 2100 is plotted simultaneously across four warming scenarios (1.5 / 2.0 / 3.0 / 4.5°C). Dragging the year slider moves a vertical probe line and marks each scenario's remaining ice percentage at that point in time. Projected losses by 2100: 49% / 68% / 83% / 94% respectively.

RAG (Retrieval-Augmented Generation) is a technique that improves AI answers by first searching relevant documents, then feeding that context to a language model to generate accurate, up-to-date responses. Think of it like an open-book exam — instead of relying solely on memorized knowledge, the AI can look up relevant information before answering.

Real WebGL polyhedra rendered with Three.js: a true tetrahedron (d4), cube (d6), octahedron (d8), dodecahedron (d12), and icosahedron (d20). The d10 is modeled as a pentagonal bipyramid — a close, honest stand-in for the kite-faced trapezohedron real d10 dice use, without claiming geometric perfection I can't verify in this build.

RAG (Retrieval-Augmented Generation) RAG lets a language model answer questions using your own documents instead of relying only on what it memorized during training. It works in two phases: Indexing (offline, done once per document) Documents → Chunking → Embedding → Vector Store Query (online, done per question) User Query → Query Embedding → Retrieval → Augmentation → Generation When a question comes in, it's converted into a vector and compared against the stored document vectors to find the most similar chunks. Those chunks are inserted into a prompt alongside the question, and the model generates an answer grounded in that retrieved context — rather than guessing from memory alone.
