A New Host, Server and Site Generator

And we are back! It must be a year now since my old site donw.org went dark for many reasons, including being busy working on my own game. There’s some big changes with this new setup: I own the domain donw.io this time round. I’ve gone through a bunch of domains – donw.org, donw.co.uk, etc. – that I used to pay somebody else to manage for me. That was obviously not the right way of going about this as I no longer own them.

Quaternions and Dual Quaternion Skinning

For some reason I like quaternions. I fell in love with complex numbers back in school when I found out that they made more sense than real numbers. While it might not exactly be helpful to visualise quaternions as an extension of complex numbers, there’s something in there that just grabs at me. Unlike previous posts, I’ve managed to update to D3D11 so I’ll be discussing implementation details in terms of HLSL (Shader Model 4, as I also have a D3D10 dev machine).

Reflection in C++, Part2: The Simple Implementation of Splinter Cell

The first part in this series on Reflection in C++ gave a high level overview of many of the possibilities open to you when adding reflection to your games. In this second part I’m going to go into details and cover the system used to aid the rendering engine in Splinter Cell: Conviction (SC5). The motivation for the development of the SC5 engine was a clean break from the past. We were working with a very, very large code base that used Unreal 2.5 with many years of modifications and rewrites.

Reflection in C++, Part 1: Introduction

If there was one job I’d love to do other than writing games it’d be writing compilers. This probably explains my obsession with the subject of reflection; a topic I’ve been hammering away at for almost 10 years now. Having written a few compilers in the past, it became glaringly obvious to me that reflection would be quite simple to add to C++ – if you’re willing to place some limits on it – and that the language has suffered from its absence.
