One of the main delays was getting the sample code out of my engine, and cleaning it up so it can be used as a learning tool. Unfortunately most of the code was hacked on as I fixed issues in the LPP renderer, and added features.

I have a fair bit of the article written, however recently I was implementing shadows and realised that I never thought about how they would integrate into the system, so I decided to rewrite my own renderer (which should not take long) and at the same time keep the code clean so it can serve as a sample as well.

This means I will probably also have Directional Light shadows in the sample. This then allows me to write about point lights, and spotlights later on, and include shadows for both.

So again, sorry for the delay, I am working hard to get it out soon.

As an aside, I noticed that Game Programming Gems is getting an 8th Edition, something I was not expecting, so with that, GPU Pro, and Game Engine Gems, I might be able to find some more cool things to write about.

Thank You for your patience.

As this implementation and sample is a part of my own engine, I need to split the code from the main project and ensure it is readable and in a suitable educational state. This should not take too long, so if you are watching this blog, I will post when this code is available, and link to it in the original article as well.

Sorry for any inconvenience, I hope the article will satisfy your LPP needs in the meanwhile. As usual if you have any questions, post them in the comments of the respective article and I will answer them as soon as possible.
