We will be implementing a simple toy ray tracer in this course. Ray tracing is a very important 3D graphics rendering technique. We normally emulate how light works: we emulate the fresnel effect, emulate bounce lighting, emulate global illumination, and so on. With ray tracing we “simulate’light: we follow light how it actually operates in the real world (but with a twist). As such we get a lot of effects for free:- Colour Bleed- Bloom-Ambient Occlusion- Realistic Shadows- Shadow Fallout- Diffuse MaterialsAll of these would take a lot of code to emulate but as you will see in this course, these can be implemented very easily using ray tracing. In this course we will be doing the following:1)Implement a triangle primitive (you can use this to render OBJmeshes as a challenge)2) Implement sphere primitive3) Implement area lights4) Implement direct lighting for diffuse materials5) Implement indirect lighting for diffuse materials6) Render a variation of the famous Cornell Box sceneIf you love making things from scratch, you will love this course. In a little over an hour, you will make your own ray tracer from scratch. This course is oriented towards beginners and so should be easily picked up by anybody.
