setSmoothShading()

setSmoothShading(smooth, smoothingAngle?): void;

Defined in: src/classes.ts:473

Control surface shading style (visual only, doesn't modify geometry)

Parameters

smooth

boolean

If true, uses smooth shading (interpolated normals). If false, uses flat shading (face normals)

smoothingAngle?

number

Optional angle threshold in degrees (0-180). Edges above this angle remain sharp

Returns

void

Example

// Enable smooth shading for organic surfaces
surface.setSmoothShading(true);

// Smooth shading with 30° threshold (sharp edges preserved)
surface.setSmoothShading(true, 30);

// Flat shading for faceted/crystalline look
surface.setSmoothShading(false);

applyLaplacianSmoothing()

applyLaplacianSmoothing(
   iterations?, 
   lambda?, 
   method?, 
   preserveBoundaries?): void;

Defined in: src/classes.ts:509

Apply Laplacian smoothing to the surface vertices (modifies geometry)

Parameters

iterations?

number = 1

Number of smoothing iterations (1-10). More iterations = smoother surface

lambda?

number = 0.5

Smoothing strength (0-1). 0 = no effect, 1 = maximum smoothing per iteration

method?

"laplacian" | "taubin"

Smoothing algorithm:

• 'laplacian': Standard smoothing, may shrink surface
• 'taubin': Alternates shrink/expand to preserve volume

preserveBoundaries?

boolean = true

If true, boundary edges remain fixed

Returns

void

Example

// Gentle smoothing to reduce noise
surface.applyLaplacianSmoothing(2, 0.3, 'laplacian', true);

// Aggressive smoothing while preserving volume
surface.applyLaplacianSmoothing(5, 0.5, 'taubin', true);

// Smooth including boundaries (may distort edges)
surface.applyLaplacianSmoothing(3, 0.4, 'laplacian', false);

Defined in: src/classes.ts:559

Create a smoothed copy of this surface

Parameters

iterations?

number = 1

Number of smoothing iterations

lambda?
