    outsideInstanceCountOfDefaultStride: number = 4

    外部实例化数组stride数量，默认为4 1、storage和uniform的offset stride都是256byte 2、为什么是4：简单以矩阵为测算依据（每个矩阵16byte，4x4矩阵常用，而且是常用中最大的类型），64*4=256byte，所以4个4x4的矩阵为一个stride。

    Methods

    _destroy

    • 检查相关storage buffer的状态，根据instance数量进行创建、更新或保持。

      1、preUpdate 中调用

      2、目前uniform 和 storage的offset 最小值为256byte

      Parameters

      • bufferList: { byteSize: number; name: string }[]

        buffer list

      Returns void

    • 获取bind group 的binding,固定的与shader中的顺序对应 说明： 1、bufferGPU使用的对象，没有使用Map。原因是需要有通用的占位Storage buffer，直接指向对象可以共享占位GPUBuffer。 2、对象不能保障顺序，所以需要一个单独绑定的顺序。

      Parameters

      • name: string

      Returns number

      number

    • 更新顶点数据， 1、如果是数组形式，直接更新 2、如果是I_vsAttribute，更新data
      3、其他暂时不支持，没有必要

      Parameters

      • name: string

        顶点数据的名称

      • data: number[]

        顶点数据

      • Optionaloption: { stride?: number; type?: "uint32" | "float32" | "int32" }

        顶点数据的类型和步长

      Returns void

    • 1、矩阵操作一般来说： CPU中：SRT(右乘)，行向量列矩阵=行向量 GPU中: TRS(左乘)，列矩阵列向量=列向量

      2、更新矩阵的顺序是先进行线性变换，再进行位置变换。其实是没有影响，线性工作在3x3矩阵，位置变换在[12,13,14]，列优先。

      3、旋转部分，四元数优先，然后后轴旋转。 A、在模型gltf中，旋转使用四元数。

      Returns Float32Array

    • 更新entity的自定义属性 1、更新entity的uniform 通用 2、更新entity的instance buffer 3、更新entity的world matrix buffer 4、更新entity的morphtarget buffer 5、更新entity的joint matrix buffer 6、检查是否有新摄像机，有进行更新 7、检查是否有新光源，有进行更新 8、DCG的uniform更新

      Parameters

      Returns Promise<void>
