    索引buffer的bundle，用于绑定到DC的index buffer 。GLTF使用 index buffer bundle , used for bind index buffer to DC .gltf use

    interface I_indexGPUBufferBundle {
        buffer: GPUBuffer;
        byteSize?: number;
        count: number;
        format: GPUIndexFormat;
        name?: string;

    byteSize?: number
    count: number
    format: GPUIndexFormat
    name?: string

    顶点缓冲区名称 20260316增加，目的动态更新vertex GPUBuffer使用。不推荐使用动态更新vertex GPUBuffer，有写入成本。之后会建立dynamicMesh 类。

    offset?: number
    size?: number

    读取数据的大小，默认=countarrayStride default: countarrayStride
