We didn’t have a proper 3D television at that time and we had to use paper anaglyph red-and-green (or cyan to be exact) glasses to see the 3D image on our monitors. We had the first 3D version of SSHD running in autumn 2009. Previously, every asteroid chunk and every enemy was in a separate drawcall in the stereo version they go out in a few fell swoops. We solved the issue by moving vertex processing from GPU to SPU and merging as many objects as possible to one drawcall. Polygons – we have lots of objects with lots of polygons and massive particle effects. The main challenge of making stereoscopic SSHD was mainly drawcalls and Luckily, we had 50 per cent of the SPU power left, so we tapped into that. That was, of course, just the beginning: after that we had to optimize a lot, as we now had 8.3ms instead of 16.7ms to render a frame. As the engine is highly modular it was mainly a matter of adding stereoscopic cameras and configuring the engine to render everything twice. We had been working on our next version of our game engine for over a year and replaced the core engine with a newer one.
So, we got to work and thought about how on earth we are going to be able to render TWICE the amount of stuff than before as now we basically needed to get the refresh rate from 60fps to 120fps to produce stereoscopic pictures.įor the more technologically inclined people reading this blog, here’s some insight on what we had to do.

The first one was that we were really concerned over whether we would be able to develop a proper 3D version of the game without compromising full 60 frames per second gameplay.Īlso, we hadn’t personally seen proper 3D images in action and the premier of Avatar was half a year away.
Our first reaction was that it sounded interesting, but we were doubtful whether 3D would ever work or be even possible to do for SSHD for a couple of main reasons. We first heard of Sony’s 3D plans when our producer, Phil Gaskell, asked us to think about a stereoscopic 3D version of our PSN hit Super Stardust HD (SSHD) in summer 2009.
