Okay, I’ll state this up front: I’m probably not going to use this approach in my own engine because of many issues inherent with Variance Shadow Mapping. However, I think I did end up with some interesting results to play with, so if VSM with fixed penumbra sizes (or just for filtering) is working well…
Introduction It’s been a while since last time, when I promised a general method for depth reconstruction regardless of projection type. I had told myself to do it “soon”. Due to lack of time partly caused by moving to Ghent and other random occurrences “soon” changed into “sooner or later” and finally we’ve arrived at…
Introduction [edit] To start things off more easily, I decided to limit this post to perspective projections and move on to the generalization (including orthographic projections) in a next blog post. When doing deferred shading or some post-processing effects, we’ll need the 3D position of the pixel we’re currently shading at some point. Rather than…
Albeit with trembling knees, I’m very excited to announce I’ll be speaking at FMX this year, ‘Europe’s most renowned conference on digital entertainment’. It’s an intimidating place to be, with many of my heroes either in the organisation or in the speaker list! Luckily I won’t be alone; the session will be part of the…

As mentioned in the release post, one of the new features is “multipass shading”. If you’re not into 3D rendering programming,…
