Ray-tracing is a powerful method that has been used for decades to create realistic images by trying to simulate how light bounces around a scene.
Here is a 1980s-era example of a ray traced scene created on a home computer.
Tariq's talk will focus on gently introducing the basic concepts and algorithm for ray-tracing, but also give a taste of more sophisticated methods used in modern rendering:
• the core idea - following rays and their reflections
• some of the simple algorithms and maths
• simple Python code to demonstrate the core idea
• a short discussion of some additional methods - reflections, haze, texture
• free open source tools you can use yourself to create raytraced scenes - e.g. povray, blender
• a taste of modern approaches to rendering realistic scenes, such as radiosity
Here is a modern rendering of an image generated by more sophisticated simulation of light, sourced from more incredible examples here. Really, this scene is not a photo, it is generated entirely algorithmically!
The talk will start at 7pm, you can arrive from 6.30pm.
