The Games Developer Conference starts on Monday, so Sunday gives a good opportunity to try to get over the jet lag and wander round the city. That’s exactly what we did. After starting at the shops in fisherman’s wharf we walked towards the bridge, which was obscured by a heavy fog, then up the hill and back round towards the city. I think we covered about nine miles in all. After that we walked down to the convention centre to register before heading back to the hotel.

Monday saw the start of the conference. I mostly switched between sessions on the math and the graphics tracks. I learnt all about Grassmann Algebra, which is a more generalised version of vector algebra that I’m more familiar with. Then I learnt about some important considerations when introducing randomness into games, and then rotations using quaternions.

In the afternoon I deviated a little to see a session on using OpenCL for AI, and then I spent the rest of the day in the graphics track, covering shader optimisation in DirectX, optimizing DirectX, tessellation, volumetric rendering for shadows and god rays, and hair and fur shaders.

It was a busy day, but then it always is at GDC. There’s just too many great sessions on at a time!
