Inline vs Indirect Raytracing 微软的DirectX Raytracing API支持通过两种主要方法进行Raytracing。第一种是Inline Raytracing,其中一个大型着色器程序既处理遍历BVH,也处理光线击中或未击中物体时的相应光照计算。第二种是Indirect Raytracing,调用单独的着色器程序来处理光线是否命中。当然这是一个简化的解释,建议查阅微...
AMD FidelityFX进化完全体:RayTracing+FSR效果测试 本测试纯属兴趣使然,欢迎在评论区讨论 一直以来都有AMD fidelityFX效果的争论,因为大部分特效都没有实装游戏,应用得比较广泛的CAS效果也显得一般。但是明显AMD并没有就此放下自家的特效群,6月直接整了一波猛的,公布了自家的SuperResolution,从此A家的超分水平又上了一...
