上面的是没有用raytracing,用的传统CSM(Cascade Shadow maps)动态阴影,跑了52 fps。 同样的场景,同样的视角,Ray tracing 跑了73 fps,可以看出光追在动态阴影表现卓越。 其实可能确定室外,大环境更适合用raytracing,现在主机常见的室外做法是,太阳光产生 动态阴影,环境中可能有多盏点光源不产生阴影,共同作用达到动态...
ray tracing 课程里还未讲到辐射度量学 所以是没有给光线能量定义的 所以认为这些光线能量就是反射点 那个点的颜色值代替能量 当然 如果直接打到光源上,算光源本身能量 那么view空间里 各种点的着色结果怎么算的? 在ray tracing里,没有对空间这些点的着色再次分析,只思考了如何对屏幕着色过程从光线角度分析 所以这些...
4A games是成立于2006年,乌克兰开发商,一直做metro系列游戏,三个大版本,中间两个重制版。 技术上一直metro是比较激进的,是硬件厂商show技术的常客,这次raytracing也没有缺席. 一些细节的效果对比可以看这里: DigitalFoundry聊地铁逃离的光线追踪技术效果_哔哩哔哩 (゜-゜)つロ 干杯~-bilibiliwww.bilibili.com/vid...
