I have been deciding to participate in Challenges for quite long time, mainly because I personally wanted to. And when DOOM was voted in, I decided I had to participate.
Of course I have to start somewhere (I made a road map, which is something I'm trying to hold to - and throughout the challenge I'm going to switch between working on art and working on source code). So let's consider this as first post, and let's see what I will manage to finish in the end. A little sneak peek into how the project is looking at current stage.
Some of you may have recognized that this is Sponza Atrium model (it is not easy to recognize it though - as the image is actually showing barycentric coordinates in red/green channel and distance traveled along the ray in blue) which I'm using for testing, as I'm working on using a custom GPU real time ray tracer as renderer (it is DOOM after all, which originally used a ray caster - so for me, it was natural to use a ray tracer).
