animation.createClip

animation.createClip¶

Summary¶

animation.createClip creates a clip over packed Wasm sampler and transform-channel tables. The optional owned-allocation lists transfer responsibility for those exact allocations to the clip; dispose() releases them.

Syntax¶

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

Parameters¶

Name	Type	Required	Description
`descriptor`	`AnimationClipDescriptor`	Yes	Packed sampler/channel tables, clip time range, name, and optional Wasm allocations whose ownership transfers to the clip.

Returns¶

AnimationClip - Clip that borrows or owns the descriptor's packed Wasm data as specified.

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	Human-readable clip name used for debugging, UI, or lookup.
`samplerCount`	`number`	Yes	Number of packed sampler records reachable from `samplersPtr`.
`channelCount`	`number`	Yes	Number of packed animation channel records reachable from `channelsPtr`.
`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	Clip start time in seconds.
`endTime`	`number`	Yes	Clip end time in seconds.
`ownedF32Allocs`	`ReadonlyArray<{ ptr: WasmPtr; len: number }>`	No	Float32 Wasm allocations transferred to the clip and freed by `dispose()`.
`ownedU32Allocs`	`ReadonlyArray<{ ptr: WasmPtr; len: number }>`	No	Uint32 Wasm allocations transferred to the clip and freed by `dispose()`.

WasmPtr¶

type WasmPtr = number;
