    Interface IV_MeshEntity

    mesh的顶点结构与材质，各有一个，一一对应

    顶点属性 和几何体二选一

    Type Declaration

    • Optionaldata?: {
          indices?: T_indexAttribute;
          vertexStepMode?: GPUVertexStepMode[];
          vertices: { [name: string]: T_vsAttribute };
      }

      顶点数据 与几何体二选一

      • Optionalindices?: T_indexAttribute

        索引数据

      • OptionalvertexStepMode?: GPUVertexStepMode[]

        顶点步长模式

      • vertices: { [name: string]: T_vsAttribute }

        顶点数据

    • Optionalgeometry?: BaseGeometry

      几何体 与顶点数据二选一

    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。

    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

    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

    update?: (scope: any) => any

    自定义更新functon()

    updateAtEnd?: (scope: any) => any

    在最后执行调用

    wireFrame?: {
        color?: weVec4;
        enable: boolean;
        indices?: number[];
        offset?: number;
        wireFrameOnly?: boolean;
    }

    线框 wireframe

    Type Declaration

    • Optionalcolor?: weVec4

      线框颜色，默认黑色(0,0,0,1) 数值范围：0-1

    • enable: boolean

      是否显示线框

    • Optionalindices?: number[]
    • Optionaloffset?: number

      线与面的偏移量 线框宽度，默认1 数值范围：0.01-10, 计算公式有VS和FS两种，目前为了简单使用的是FS的； VS计算公式在shader/entity/mesh/wireframe.vs.wgsl FS计算公式在shader/material/wireframe/wireframe.fs.wgsl

    • OptionalwireFrameOnly?: boolean

      只显示线框
