    Interface IV_PointsEntity

    mesh的顶点结构与材质，各有一个，一一对应

    interface IV_PointsEntity {
        attributes: {
            data: {
                indices?: number[];
                vertexStepMode?: GPUVertexStepMode[];
                vertices: { [name: string]: number[] };
            };
        };
        color?: weVec4
        | weVec3;
        cullMode?: GPUCullMode;
        drawMode?: I_drawModeIndexed | I_drawMode;

    顶点属性 和几何体二选一

    Type Declaration

    • data: {
          indices?: number[];
          vertexStepMode?: GPUVertexStepMode[];
          vertices: { [name: string]: number[] };
      }

      顶点数据

    color?: weVec4 | weVec3

    1、颜色，与material互斥 2、顶点着色，需要使用VertexMaterial材质

    cullMode?: GPUCullMode

    剔除面 : "front" | "back" | "all"

    drawMode?: I_drawModeIndexed | I_drawMode

    绘制方式

    dynamicAttribute?: boolean

    是否动态attribute数据 1、默认false。涉及BOL和底层的CPU到GPU数据的传输，如果需要动态更新attribute数据，则需要设置为true。else 2、动态顶点属性的： A、数据的内容在运行时有动态变化； B、数据的长度在运行时有动态变化； 3、drawMode 不可以变化：索引模式或非索引模式 4、属性数据和索引数据只支持 number[] 类型 A、DCG中不适用pointer，而是使用单独GPUBuffer。 B、后续使用setVertexBuffer() 和setIndexBuffer()来重新绑定顶点数据和索引数据。

    emulate?: T_PointEmulate

    模拟的形状

    instance?: I_entityInstance

    内部实例化参数，默认为只有当前entity，无其实例化

    invertNormal?: boolean

    是否反转法线，默认false

    material?: BaseMaterial

    1、材质, 与颜色互斥 2、默认是没有材质，只有在emulate有值的时候才会有材质

    matrix?: weMat4
    name?: string
    position?: weVec3
    primitive?: GPUPrimitiveState

    图元状态

    quaternion?: weVec4
    relation?: T_worldRelationTransmit
    rotate?: weVec4
    scale?: weVec3
    shaderCode?: string

    自定义shader主代码，包括VS和FS

    shaderCodeFunction?: string

    自定义shader 函数代码，包括VS和FS

    shadow?: I_optionShadowEntity

    阴影选项

    size?: number

    1、默认是,webGPU的一个像素(没有emulate的情况) 2、模拟的形状需要尺寸,float

    update?: (scope: any) => any

    自定义更新functon()

    updateAtEnd?: (scope: any) => any

    在最后执行调用
