Ray tracing is a rendering technique that can realistically simulate the lighting of a scene and its objects by rendering physically accurate reflections, refractions, shadows, and indirect lighting. Ray tracing generates computer graphics images by tracing the path of light from the view camera (which determines your view into the scene), through the 2D viewing plane (pixel …

Ray tracing algorithm is used when the cost to implement is not an issue and time to render is tolerated. This is because ray tracing algorithm needs high costs and also time to render the image is relatively very high. Hence, this algorithm can be implemented in film/television visual effects as they need high definition and the best quality videos.

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 ...

As a graphic technology, ray tracing allows for the fluid simulation of lighting effects. An algorithm emits rays in the form of a 3D graphic, traces the rays’ paths and then calculates a realistic lighting model. Anyone that is familiar with computer games and graphics cards will inevitably be familiar with ray tracing too, as it is usually used with these technologies.

8.1.2 Recursive Ray Tracing. Basic ray casting can be used to compute OpenGL-style rendering and, with the addition of shadow rays, to implement shadows as well. More features can be implemented by casting a few more rays. The improved algorithm is called ray tracing. Consider specular reflection. In OpenGL, specular reflection can make an object look shiny in the sense …

Basic Ray-Tracing • Ray tracing proceeds as follows: – Fire a single ray from each pixel position into the scene along the projection path (a simple ray-casting mechanism) – Determine which surfaces the ray intersects and order these by distance from the pixel – The nearest surface to the pixel is the visible surface for that pixel
