  • An example of polygon conflict detection based on c# implementation

    Time:2021-10-25

    preface Previously, I encountered a problem of polygon conflict detection in the project. Through Baidu, Bing and Google, I found that the existing schemes are either incomplete scene coverage or implemented through third-party class libraries (which can hardly be decompiled). However, the use of third-party class libraries is prohibited in the project, so I implemented […]
