Ray tracing [C++ & SDL2] - Episode 4 - Light...

Ray tracing [C++ & SDL2] - Episode 4 - Light...

In this episode we extend our code to allow support for multiple objects and add support for simple point lights, going on to produce an image of the red sphere shaded by the light of a single point source. We will go on to build on this in later episodes, adding greater complexity as we go, but we are already producing an image that is starting to look a bit more interesting!

As with all of my videos, I show the code that I have developed to solve the particular problems that I need to solve, with the hope that it may provide sufficient background and inspiration to allow you to go on to develop your own code if you wish to. My code may not be the most appropriate solution to the problem you are trying to solve, so I urge you to consider the problem carefully and decide for yourself on the most appropriate solution. I make every effort to ensure that my code works as it should and is free of bugs, but of course I cannot provide any guarantees. If you use my code as shown, I strongly encourage you to make sure that you test it thoroughly to ensure that it works as you need it to. If you find a bug, do please let me know in the comments!
