Shader achieves a cutout effect. Shader realizes the preservation of hollow marks (can be used as an eraser or basic fog dispersion function).
Shader实现镂空效果；Shader实现保留镂空痕迹(可做橡皮擦或基础的迷雾散开功能)。有完整的Demo实现。Instructions in EnglishShader achieves a cutout effect.Support changing basemaps, hollow styles, color overlays.The cutout style supports zooming (mouse wheel zooming out has been implemented in the sample).Support mouse drag following, target object following, blend mode (implemented in the sample for reference).Shader realizes the preservation of hollow marks (can be used as an eraser or basic fog dispersion function).Retaining the hollow traces supports resolving modifications, increasing or decreasing the accuracy to achieve different effects.Use Shader to achieve the drawing part, the performance is efficient.Exposed parameter control and detailed annotations are easy to use.The implemented resource scripts are concise and easy to embed.The sample implements a complete set of common functions for easy reference.中文说明Shader实现镂空效果支持更换底图、镂空样式、颜色覆盖叠加镂空样式支持缩放(样例中已实现鼠标滚轮放大缩小)支持鼠标拖动跟随、目标物体跟随、混合模式(样例中已实现可做参考)Shader实现保留镂空痕迹(可做橡皮擦或基础的迷雾散开功能)保留镂空痕迹支持分辨修改，提高或降低精度实现不同效果使用Shader实现绘制部分，性能高效。暴露丰富的参数控制、详细的注释便于使用。实现的资源脚本等简洁方便嵌入。样例实现了完整的常用功能，方便参考使用。Technical details EnglishImplement the function of openwork by using "Res/SmalBoxHollowPlane.prefab".Adjust the parameters in the Inspector of the component MotionMgr to achieve effects such as cutout erase, see the demo in Example.Change the effect by adjusting the material parameters in "Res/SmalBoxHollowPlane.prefab".Overlaycolor Adjust the overlay color.MainTexture adjusts the main display diagram.SubTexture shows the hollow effect according to this map (the transparency of the hollow is determined by the size of the R value in the figure).SubTexture2 eliminates the need for manual assignment and is used to record retention traces.Scale can adjust the size of the cutout effect (example control in Example).Pos can adjust the hollow position (complete mouse and object control example in Example).技术细节 中文通过使用"Res/SmalBoxHollowPlane.prefab"实现镂空的功能。调整组件MotionMgr的Inspector中的参数实现镂空擦除等效果，具体参看Example中的演示。通过调整"Res/SmalBoxHollowPlane.prefab"中的材质参数改变效果。Overlaycolor 调整覆盖颜色MainTexture 调整主要显示图SubTexture 根据此贴图显示镂空效果(根据图中的R值大小决定镂空的透明度)SubTexture2 无需手动赋值，用来记录保留痕迹Scale 可以调节镂空效果大小(Example中有例子控制)Pos 可以调节镂空位置(Example中完整的鼠标、物体控制例子)
