In computer graphics, ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects. The technique is capable of producing a high degree of visual realism, more so than typical scanline rendering methods, but at a greater computational cost. This makes ray tracing best suited for applications where taking a relatively long time to render can be tolerated, such as in still computer-generated images, and film and television visual effects (VFX), but more poorly suited to real-time applications such as video games, where speed is critical in rendering each frame.
“This is a simple ray tracer written in uLisp, running on a colour TFT display. The scene contains five spheres and a plane.”
“ello! This is part one of a short series of posts on writing a simple raytracer in Rust. I’ve never written one of these before, so it should be a learning experience all around. So what is a raytracer …
