Testing ideasThe first thing to do is to convert box to AABB and then determine if the center is in box, using the SATIf the center is inside the box, it must intersect,If it is not within the center of the circle, there are four cases, intersecting the vertices, intersecting with the faces, and intersecting the polygons, where the determination is also determined by the SAT.In two dimensions, if the center is not inside the box, there are a couple of casesJust compare the length of the red line
LeakCanary: simple and crude memory leak detection tool, leakcanary Leak Detection
Almost every programmer may experience memory leakage during development. How can we detect memory leakage in the app? Square introduces LeakCanary, a simple and crude tool for detecting memory leaks.
What is memory leakage?
Memory leakage refers to the failure of the program to release memory that is no longer in use due to

Memory leakage and a simple detection method, memory leakage detection1. What is Memory Leak )? Simply put, a memory space is applied for and is not released after use. Generally, the longer the program runs, the more memory it occupies, and the entire system crashes. A piece of memory applied by the program, and no pointer points to it, the memory will be leaked. 2. Hazard of Memory leakage
From the perspective of user programs, memory leakage does n
