WasmGPU.animation.createClip

WasmGPU.animation.createClip¶

Summary¶

WasmGPU.animation.createClip creates animation runtime objects used for clip sampling, playback, and skinning.

Syntax¶

WasmGPU.animation.createClip(descriptor: AnimationClipDescriptor): AnimationClip
const result = wgpu.animation.createClip(descriptor);

Parameters¶

Name	Type	Required	Description
`descriptor`	`AnimationClipDescriptor`	Yes	Descriptor object that defines the initial configuration for this runtime object.

Returns¶

AnimationClip - AnimationClip runtime object created for animation workflows.

Type Details¶

AnimationClipDescriptor¶

type AnimationClipDescriptor = {

    name: string;

    samplerCount: number;

    channelCount: number;

    samplersPtr: WasmPtr;

    channelsPtr: WasmPtr;

    startTime: number;

    endTime: number;

    ownedF32Allocs?: ReadonlyArray<{ ptr: WasmPtr; len: number }>;

    ownedU32Allocs?: ReadonlyArray<{ ptr: WasmPtr; len: number }>;

};

AnimationClipDescriptor Fields¶

Name	Type	Required	Description
`name`	`string`	Yes	String input controlling `name` for this operation.
`samplerCount`	`number`	Yes	Numeric input controlling `samplerCount` for this operation.
`channelCount`	`number`	Yes	Numeric input controlling `channelCount` for this operation.
`samplersPtr`	`WasmPtr`	Yes	Wasm pointer to packed animation sampler table data.
`channelsPtr`	`WasmPtr`	Yes	Wasm pointer to packed animation channel table data.
`startTime`	`number`	Yes	Numeric input controlling `startTime` for this operation.
`endTime`	`number`	Yes	Numeric input controlling `endTime` for this operation.
`ownedF32Allocs`	`ReadonlyArray<{ ptr: WasmPtr; len: number }>`	No	Array input for `ownedF32Allocs` used by this API call.
`ownedU32Allocs`	`ReadonlyArray<{ ptr: WasmPtr; len: number }>`	No	Array input for `ownedU32Allocs` used by this API call.

WasmPtr¶

type WasmPtr = number;

Example¶

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

const descriptor = { name: "walk", samplerCount: 0, channelCount: 0, samplersPtr: 0, channelsPtr: 0, startTime: 0, endTime: 1 };
const result = wgpu.animation.createClip(descriptor);
console.log(result);
