setTranslation

setTranslation(pos: Float32Array): void

Parameters
- pos: Float32Array
  :Vec3
Returns void
- Defined in src/we/core/organization/nodeSpace.ts:276

translate

translate(pos: Float32Array): void
在现有matrix（原有的position）上增加pos的xyz，将entity的矩阵应用POS的位置变换，是在原有矩阵上增加

  :Vec3
Returns void

update

update(clock: Clock, updateSelftFN?: boolean, updateAtEndFN?: boolean): boolean
正常更新 1、更新空间属性

2、调用super.update()更新
Parameters
- clock: Clock
  Clock 时钟
- updateSelftFN: boolean = true
  是否调用自身的updateSelf(),默认=true 此参数可以方便子类重载时，决定调用的updateSelf()的时间顺序或是否调用updateSelft()
- updateAtEndFN: boolean = true
  是否调用自身的updateAtEnd(),默认=true
Returns boolean
Overrides RootGPU.update
- Defined in src/we/core/organization/nodeSpace.ts:357

updateMatrix

updateMatrix(): Float32Array
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
