Originally published at: From Rasterization to Full Real-Time Path Tracing: The Evolution of Graphical Rendering Techniques | NVIDIA Technical Blog
Video game artists have become highly capable at pushing the limits of rasterization, but it remains a complicated, time-consuming process, ubiquitous only because it’s computationally cheap. There are some challenges that simply can’t be overcome through sophisticated work-arounds. “The problem here is that most lighting interactions are not local. Most interesting lighting interactions turn out…
