geometry.parametricSurface

geometry.parametricSurface¶

Summary¶

geometry.parametricSurface samples a 3D function over a UV grid and computes indexed triangles, normals, and texture coordinates. Both parameter ranges default to [0, 1], resolution to 128 × 128, and cells touching non-finite samples are skipped by default.

Syntax¶

WasmGPU.geometry.parametricSurface(descriptor: ParametricSurfaceDescriptor): Geometry
const result = wgpu.geometry.parametricSurface(descriptor);

Parameters¶

Name	Type	Required	Description
`descriptor`	`ParametricSurfaceDescriptor`	Yes	3D sampling function, U/V ranges, grid resolution, sidedness, and invalid-cell policy.

Returns¶

Geometry - Indexed sampled surface with computed normals, UVs, and bounds.

Type Details¶

ParametricSurfaceDescriptor¶

type ParametricSurfaceDescriptor = {

    f: (u: number, v: number) => [number, number, number];

    uMin?: number;

    uMax?: number;

    vMin?: number;

    vMax?: number;

    uSegments?: number;

    vSegments?: number;

    plane?: "xy" | "xz" | "yz";

    skipInvalid?: boolean;

    doubleSided?: boolean;

};

ParametricSurfaceDescriptor Fields¶

Name	Type	Required	Description
`f`	`(u: number, v: number) => [number, number, number]`	Yes	Sampling callback used during procedural curve/surface generation.
`uMin`	`number`	No	Lower bound of the sampled U interval.
`uMax`	`number`	No	Upper bound of the sampled U interval.
`vMin`	`number`	No	Lower bound of the sampled V interval.
`vMax`	`number`	No	Upper bound of the sampled V interval.
`uSegments`	`number`	No	Number of subdivisions along U.
`vSegments`	`number`	No	Number of subdivisions along V.
`plane`	`"xy" \\| "xz" \\| "yz"`	No	Plane in which 2D procedural geometry is embedded (`xy`, `xz`, or `yz`).
`skipInvalid`	`boolean`	No	Whether cells touching non-finite callback results are omitted.
`doubleSided`	`boolean`	No	Whether indices are emitted for both winding directions.
