ROUGHNESSLAB · SURFACE SYNTHESIS · 3D

Real-time 3D surface roughness simulator

Adjust Sa, Ssk, Sku, anisotropy and spatial frequency. Watch a reproducible synthetic surface change and compare the targets with its computed descriptors.

Educational simulation · Not a measurement or a validated ISO evaluation

☷Input parameters

Sa target · mean roughness height

Scales the mean absolute surface height (µm).

Ssk target · skewness

Negative: extreme valleys; positive: extreme peaks.

Sku target · kurtosis

Controls the prominence of statistical tails; not surface performance.

Str target · texture anisotropy

Indicative generator control, not standardized Str.

Spatial frequency / waviness

Adjusts lateral wavelength; ΔX=ΔY=1.5 µm.

Texture orientation

Preferred direction of the synthetic texture.

Vertical exaggeration

Affects 3D rendering only, not parameters.

Input parameters

Σ z · ΔX, ΔY
