Things have been a little slow recently. I’ve been generally reading about other aspects of graphics programming as well as generally being busy and now I’ve come down with something. Blocked ear, runny nose, bad headaches, dizziness and more. My best excuse for not getting as much programming done has to be that I’ve given coffee a bit of a hiatus for a while just to get some of the benefits of caffeine back. Good for the health though! … :P I’ve still managed to get the majority of the ray…

Finally got around to adding those few lines of code to add textured walls to the ray caster. A few details: The texture isn't mine, I merely found it via Google Images with the term "wall texture" and it has the filename Wall_Texture_by_shadowh3.JPG There's still a problem with the corners of the grids having a weird fringe. It's better than it was, but still not right. Haven't tracked that down yet, but have some ideas The somewhat hybrid mix (Courtesy of XNA) of performing the ray casting…

Just a little more to add. I have shadows working but there's a bug or two in there that I can't seem to shift, but here's what I've got anyway:

Two updates in one day. This is probably a first on my blog :) Here's an image of a single reflective sphere in the middle of three other spheres of various colours with lighting and shadows: Here's a quick look at all of the spheres featuring reflectivity and how they look when recursively casting off one and another:

Here's what I have so far: Of course, it's still very much some ways off the high quality rendering that ray tracing can be known for, but it's a good learning experience all the same.
