Video & Motion
Easing library, animation patterns, and cinematic templates for branded video
Motion Principles
Five rules governing every animation in the Hermes visual system.
cubic-bezier(.16,1,.3,1) for UI entrances. Never use linear for anything except progress bars and scan lines.Easing Library
Click each track to see the easing in action.
--ease-spring: cubic-bezier(.16,1,.3,1); --ease-smooth: ease-in-out; --ease-linear: linear; --stagger-card: 220ms; --stagger-char: 50ms;
Animation Patterns
Live CSS-only demos of core animation patterns used across all cinematics.
Cinematic Templates
Four reusable cinematic sequences. Each auto-plays on scroll with a replay button.
Canvas Patterns
Documented recipes from vextrum_cinematic.html for Canvas-based animations.
Constellation Grid
70 nodes with proximity-based edges. Nodes drift slowly; edges form when distance < threshold. Color transitions match scene mood.
class ConstellationGrid { constructor(canvas, nodeCount = 70) { this.edgeThreshold = 120; // Nodes drift, edges form on proximity } }
Knowledge Graph
Typed nodes (entity, concept, source) with directional edges. Data packets animate along edges as colored dots. Used in pipeline visualization scenes.
class KnowledgeGraph { constructor(nodes, edges) { this.packets = []; // Data dots animate along edges } }
Gauge Render
Arc stroke-dash with color thresholds. Green > 70%, amber 40-70%, red < 40%. Central percentage label in JetBrains Mono.
function drawGauge(ctx, cx, cy, r, pct) { const startAngle = 0.75 * Math.PI; // Arc from start to pct-proportional end }
Color Grading by Scene
Which accent colors convey which emotional tone in cinematic sequences.
