    Type Declaration

    • Optionalindices?: T_indexAttribute
    • Optionaluniforms?: GPUBindGroup[] | T_uniformGroups[]

      1、最多4个bind group； 2、如果有system，system的bindGroup是0，还剩3个； 3、entity的bindGroup占用bindGroup1的位置； 4、如果IV_DC,没有定义system，则uniform不考虑system的BindGroup的问题，即raw模式（NDC）

    • OptionalunifromLayout?: GPUBindGroupLayout[] | T_BindGroupLayout[]
    • OptionalvertexStepMode?: GPUVertexStepMode[]
    • Optionalvertices?: { [key: string]: T_vsAttribute }
    dynamic?: { fs?: boolean; vs?: boolean }

    Type Declaration

    • Optionalfs?: boolean

      是否包括动态资源在binding group中 默认：false， 如果true，则需要动态绑定资源

    • Optionalvs?: boolean

      动态更新vs属性 1、attribute的内容，数量不变，内容变化 2、attribute的内容的，数量变化。要求所有属性对应的数量必须相同。

    IDS?: I_DrawCommandIDs

    ID组,TT使用，用于获取entity的Blend参数

    label: string
    render: {
        depthStencil?: false | GPUDepthStencilState;
        drawMode?: T_drawMode;
        fragment?: {
            aliasName: string;
            code?: string;
            constants?: Record<string, number>;
            entryPoint: string;
            targets?: GPUColorTargetState[];
        };
        primitive?: GPUPrimitiveState;
        vertex: {
            code: string;
            constants?: Record<string, number>;
            entryPoint: string;
        };
        viewport?: I_viewport;
    }

    Type Declaration

    • OptionaldepthStencil?: false | GPUDepthStencilState

      是否开启深度测试和深度写入 不需要深度测试的（比如没有depth输出等的），需要设置为：false

    • OptionaldrawMode?: T_drawMode

      drawMode 1、DrawCommand，不需要，其drawMode数据由运行时的renderManager传递给DC。（DC均由entity产生） 2、BaseDrawCommand，需要，由于简单绘制，比如：quad，测试用例等。

    • Optionalfragment?: {
          aliasName: string;
          code?: string;
          constants?: Record<string, number>;
          entryPoint: string;
          targets?: GPUColorTargetState[];
      }

      无,则只有VS渲染

      • aliasName: string

        alias name of fragment shader

      • Optionalcode?: string

        未定义，则FS和VS代码共用

      • Optionalconstants?: Record<string, number>
      • entryPoint: string

        默认："fs"

      • Optionaltargets?: GPUColorTargetState[]

        没有，则去scene中获取

    • Optionalprimitive?: GPUPrimitiveState
    • vertex: { code: string; constants?: Record<string, number>; entryPoint: string }
      • code: string

        shader模板

      • Optionalconstants?: Record<string, number>
      • entryPoint: string

        默认："vs"

    • Optionalviewport?: I_viewport
    renderPassDescriptor?: GPURenderPassDescriptor

    渲染RPD描述符， 1、如果有同级别中的system存在，则按照camera或light，去scene中获取 2、如果没有system： A、若有本项，则使用 B、没有，则去scene中获取NDC的RPD

    system?: {
        material?: I_DrawInputValueMaterial;
        MSAA?: T_rpdInfomationOfMSAA;
        parent?: BaseEntity;
        type: E_renderForDC;
    }

    有system：摄像机或光源模式 没有system：NDC模式

    Type Declaration

    • Optionalmaterial?: I_DrawInputValueMaterial
    • OptionalMSAA?: T_rpdInfomationOfMSAA

      DC的UUID从renderManager运行时获取，可以不设置ID

    • Optionalparent?: BaseEntity

      DC的parent， 1、entity的bindGroup占用bindGroup1的位置； 2、如果存在parent，bindgroup和bindgrouplayout通过parent.getBindGroupAndBindGroupLayout()获取 2、如果没有父实体，则entity的bindGroup使用data中的uniform数据生成bindgroup；同时layout 通过cache获取

    • type: E_renderForDC
    transparent?: GPUBlendState[]

    是否透明渲染,包括alpha 透明，物理透明
