A * is a path search algorithm commonly used in game software development. A * the algorithm is so attractive because it ensures the optimal path between any start point and any end point. We can try to use the * algorithm, except for some special scenarios. For example, if there is no obstacle between the start point and the end point and there is a clear line of sight, the line of sight
In offline rendering, KD, KS, and KT (representing the diffuse reflection coefficient, mirror reflection coefficient, and transmission coefficient of an object respectively) can be used to briefly describe the basic material of an object. For example, we set an object to: Kd = 0, Ks = 0.1, KT = 0.9, that is, after a bunch of light hits the surface of the object, 90% of it is transmitted (refraction ), the other 10% is reflected back by the surface. This means that no matter what angle the light
