光线跟踪(Raytracing) 选择光线跟踪作为辅助渲染器,这样当主渲染器(扫描线、光栅化器或光线跟踪)检测到需要折射或反射时,它将切换到仅光线跟踪模式。“光线跟踪”(Raytracing)可以产生物理上最为精确的反射、折射、阴影、全局照明、焦散和最终聚集。 反射(Reflections) 光线可以被反射曲面反射的最大次数。 请参...

在Ray Tracing In One Weekend中,构建了一个简单的路径跟踪器。在本期中,将使用BVH添加纹理、体积(如雾)、矩形、实例、灯光和对许多对象的支持。完成后,将拥有一个“真正的”光线追踪器。 光线追踪的一个启发是,大多数优化使代码复杂化,而没有提供多少加速。在这本迷你书中,我要做的是在我做出的每个设计决策...
Laser ray tracing, a technique originally developed to measure ocular aberrations from the deviations of the local ray aberrations as a function of entry pupil, was used to assess cone directionality in 29 normal eyes (seven of which underwent LASIK surgery) and seven eyes after LASIK corneal ref...
To develop a novel algorithm based on ray tracing, simulated visual performance and through-focus optimization for an accurate intraocular lens (IOL) power calculation. Custom-developed algorithms for ray tracing optimization (RTO) were used to combine the natural corneal higher-order aberrations (HOAs...
Ray Tracing vs Rasterization Conventional 3D rendering has typically used a process called rasterization since the 1990s. Rasterization uses objects created from a mesh of triangles or polygons to represent a 3D model of an object. The rendering pipeline then converts each triangle of the 3D models...
O Ray Tracing tem sido o santo graal dos gráficos há décadas porque é singular em sua capacidade de fornecer fidelidade realista a tudo o que acontece na tela. O único problema é o desempenho: são necessários milhões de operações de Ray Tracing por frame para obter resultad...

[Miller 1994] maps and scales directly with real-time ray tracing: ▪ Integral of the visibility function over the hemisphere Ω for the point p on a surface with normal nො with respect to the projected solid angle ▪ Games often approximate this in screen-space ▪ With RT, more ...
