WasmGPU.math.vec3.interp

WasmGPU.math.vec3.interp¶

Summary¶

WasmGPU.math.vec3.interp computes a weighted interpolation from a base vector and three scalar weights. Use it for custom blend and basis-combination workflows.

Syntax¶

WasmGPU.math.vec3.interp(v: number[], a: number, b: number, c: number): number[]
const result = wgpu.math.vec3.interp(v, a, b, c);

Precision-Specific Wasm Forms¶

WasmGPU.math.vec3f.interp(out: WasmPtr, v: WasmPtr, a: number, b: number, c: number): void
WasmGPU.math.vec3d.interp(out: WasmPtr, v: WasmPtr, a: number, b: number, c: number): void

These forms use caller-owned pointers to 3-element vector blocks in WasmGPU driver memory: binary32 for vec3f and binary64 for vec3d. Methods with an output pointer write that block instead of allocating a JavaScript array. See WasmGPU.math for allocation, views, aliasing, and release requirements.

Parameters¶

Name	Type	Required	Description
`v`	`number[]`	Yes	Vector input as `[x, y, z]`.
`a`	`number`	Yes	Weight for the x-component contribution in interpolation.
`b`	`number`	Yes	Weight for the y-component contribution in interpolation.
`c`	`number`	Yes	Weight for the z-component contribution in interpolation.

Returns¶

number[] - New 3D vector as [x, y, z].

Type Details¶

type Vec3 = number[]; // expected length: 3 ([x, y, z])

Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const v = [1, 2, 3];
const a = 0.2;
const b = 0.3;
const c = 0.5;
const result = wgpu.math.vec3.interp(v, a, b, c);
console.log(result);
