Whitted-style Ray Tracing • Turner Whitted introduced ray tracing to graphics in 1980 • Combines eye ray tracing + rays to light and recursive tracing • Algorithm: 1. For each pixel, trace primary ray in direction V to the first visible surface. 2. For each intersection trace secondary rays: • Shadow in direction L to light sources

Basic Raytracing. In this chapter, we’ll introduce raytracing, the first major algorithm we’ll cover. We start by motivating the algorithm and laying out some basic pseudocode. Then we look at how to represent rays of light and objects in a scene. Finally, we derive a way to compute which rays of light make up the visible image of each of ...

The ray-tracing algorithm takes an image made of pixels. For each pixel in the image, it shoots a primary ray into the scene. ... The beauty of ray-tracing, as one can see, is that it takes just a few lines to code; one could certainly write a basic ray-tracer in 200 lines. Unlike other algorithms, such as a scanline renderer, ray-tracing takes ...

Writing a Basic Ray Tracer. ... Because this lesson is just an introduction to the ray-tracing algorithm, this topic is too complex to be explained in detail. ... Conclusion: Forward ray-tracing (or light tracing because we shoot rays from the light) makes it technically possible simulate the way light travels in nature on a computer. However ...
