Hi, nice post. Are you doing something bigger using this technique, or is this just an educational sample? Also what kind of shadowing are you going to implement? Looking forward to your next post on this.

Thanks
This is currently the core of my own engine’s renderer, however from this point onwards I have split the codebase so that I can show off different ways of doing things.

This is just the first of multiple samples/articles that will build upon this, and as I add features to my engine, if they relate to this I will probably write about them.

As for shadowing, I am not sure at this time, I may do an article on adding basic shadowing to this system, or just go straight into whatever technique I will use myself.

Nice article!

Maybe you don’t need to implement a forward renderer for transparent objects. Read this article:

(in particular “Reverse Depth Peeling”).

Yeah that is true, there are alternatives that do not require a separate renderer for transparent objects. Another technique is using stippling to “alternate” between layers.

That is something I plan to look into for my own engine, and certainly write about if everything works out.
