How to use the NFTScan NFT API to develop Web3 applications on the Polygon network
Formerly known as Matic Network, Polygon is a scaling solution that provides tools to speed up and reduce the cost and complexity of transactions on blockchain networks. However, the massive activity on its blockchain has brought Ethereum to near-crippling due to growing transmission costs and congested traffic. The main purpose of Polygon’s birth is to […]

Qt determines whether a point is inside or outside a polygon (supports convex polygon and concave deformation)
The method implemented here is reproduced in https://blog.csdn.net/trj14/article/details/43190653 and https://blog.csdn.net/WilliamSun0122/article/details/77994526 It was implemented and adjusted according to Qt’s rules. There are four implementation methods below. The specific explanation of each method is explained in the reposted blog, and will not be repeated here. Here we only talk about the specific implementation of the code and […]
