What is Sgt. Conker? It is the new website for games development related articles, news, gossip and whole lot more.
Whenever you want to see something new on the XNA development front, give us a visit, or just subscribe to the site’s RSS feed.
I also take this opportunity to announce one of the upcoming features on Sgt. Conker, the Shader Challenges, where we’ll be challenging you to finish an incomplete shader, or fix a broken one, which we hope will be an interesting way for you to improve your HLSL skills. Stay tuned for this, because it’s comming in the near future, together with a whole lot more!
Adding softness to shadows
Oct 1st
In my efforts to make the shadows soft, based on the formulas for penumbras, I finally realized that my method does not support physically correct penumbra softness, but I will explain the reason for this when I do the tutorial.
Until then, here’s what I came up with, after applying some Gaussian blur to the final shadow image. (variable degree of softness)
Even if it’s not physically correct, I still think the softness looks good enough.
There’s also an interesting looking result when the radius of the Gaussian Blur depends on the distance from the light…
