Tensilux Spatial Surface

The Turing-complete spatial surface and design system of PragCore: coupling Two-Tier Material Dialogue (Bedrock vs. Optical Lens), unibody instrument consoles, viscoelastic boundary deformation, and hydrodynamic screen-space refraction.

Viscoelastic Boundary

a = -(k/m)Δp - c·v + f_ext

Drag, hover, or pull near boundaries to observe directional Poisson contraction (ν = 0.35) and 60fps damped harmonic recovery.

Material Affordance Triad

Physical Axioms of Interaction

Physical affordance dictates material selection: interactive substrates squish to attract input, while non-interactive architecture remains crystalline and rigid.

Interactive Substrate

Viscoelastic Magnetic Jelly

Soft, magnetically attractive, and directionally compliant. Stretches toward the cursor along the primary pull vector while compressing laterally.

k = 190 • ζ = 16 • ν = 0.35 • Max: 9.5px

Architectural Substrate

Rigid Aqueos Glass

Crystalline, non-deformable, and structurally monolithic. Provides immovable spatial anchoring for navigation headers, status bars, and frame partitions.

Rigid Glass • Zero Deformation • T = 0.94

Content Plane

Optically Stabilized Typography

Micro-parallax counter-shift ensures body text, numerical readouts, and iconography never suffer geometric shear or blur during extreme border stretching.

Zero Shear • Syne / SF Pro • WCAG AAA 20.58:1

UI Component Arsenal

Tensilux Viscoelastic Component Primitives

Deterministic, full-coverage interactive controls engineered with continuous squircle curvature, Total Internal Reflection (TIR) specular catchlights, and viscoelastic damped harmonic recoil.

Viscoelastic Buttons

Damped Harmonic Press

Three-tiered button hierarchy with continuous squircle curvature, top-edge specular bevel, and 280ms spring recoil on active press.

Tactile Toggle Switch

Viscoelastic Glide

ACTIVE_WAVEGUIDE

Pill track with recessed ambient drop shadow and continuous sliding thumb executing elastic snap.

Text Input Field

TIR Focus Glow

Specular top catchlight and dynamic cyan focus aura with minimum 44px touch ergonomics and zero-latency input rendering.

Segmented Control

Sliding Pill Affordance

Discrete multi-option selector with illuminated pill indicator and tactile boundary transitions.
