NVidia® OptiX™ at SIGGRAPH 2009

NVIDIA announced it’s OptiX real-time ray tracing engine at SIGGRAPH 2009, yesterday. You may recall my previous article on how GPU-based ray tracing may become the future of 3D graphics in games with the release of the GT300 family of GPUs. The fact remains, rasterised graphics ARE currently much faster than ray traced rendering, so much more powerful GPUs will be required for real-time ray tracing in games.

As David Kirk of NVIDIA put it, “Ray tracing is the technology of the future and it always will be!”

The new APIs/Engines that NVidia revealed at SIGGRAPH include additional support for applications programmers. The OptiX interactive engine is a ray tracing pipeline which will allow developers to use the C programming language in order to leverage ray tracing in their applications.

DirectX 11 Goodness!

The day has finally arrived. NVidia’s much-awaited GT300 sporting DirectX11 and a slew of new capabilities has finally taped out. If these chips pass the final foundry tests, they are expected to them some out of manufacturing by November 2009, but it will be be March 2010 before mass production will be in  full force. ‘GT300’, while not the official name, is what ‘everyone’ seems to be calling the new Nvidia GPU these days. NVidia has previously revealed GT300 to be a new cGPU architecture which is radically different from previous generation G200, G92 and the G80 GPUs. The new the cGPU designs further the general-purpose processing design that the last generation brought to market. cGPUs are quite literally GPUs imbued with CPU capabilities,  bringing graphics processors ever closer to their role as general-purpose computational devices. NVidia’s Adrianne must be looking very happy now… and maybe a little less creepy.

Necessity and Desperation

If necessity is the mother of invention then desperation is its great grandmother. I remember my first computer very well: an 80386 DX @ 40 Mhz with a 170MB Hard Disk, 2MB of RAM and a whopping 1MB SVGA Trident graphics card. We didn’t know it at the time but ‘Prof Computers’, the retailer who sold us the system, had loaded up the PC with old unreliable parts. What a bunch of charlatans and thieves! So naturally that computer would constantly break down and we’d have to take it in for service regularly.

They barely kept the system running through its warranty and as soon as that was over the system just decided to quit for good. And so my brother and I would often joke about what we believed ought to be their motto – “Prof – We keep it running.” All things considered I loved that computer to bits. It had a 7-segment LED display on the front of the case  with a Turbo button. At the default setting the 7-segment display would read 40 in bright green, but pressing the turbo button would slow down the system to 20Mhz. There was a massive Power button marked 1 and 0, a hard reset button and, get this – a lock for a computer key. Yup, as many who’ve used old systems would rememeber, most of them came with a key that you could use to lock the system. Booting up with the system locked would lead to an error message during the POST.

Growing up, I wasn’t much for gaming. Most of my time was spent programming in BASIC, Pascal and running innovative MS DOS scripts. Some of my favourites were processing command-line parameters in the form of “%1”, “%2”, … “%n”, and of course the ultimate single line command which would typically read something like:

for %t in (file1.ex1 file2.ex2 file3.ex4 somefile.exe another.dat makeEmUp.bat gorilla.bas nibbles.bas autoexec.bat config.sys)  do if not exist a:\somedir\%t copy %t ..\

At this point in time, I have three laptops. How did this happen?! I was always a desktop person, but in the last three years it seems I somehow… lost… my way. Now I’m kicking myself wondering why I kept buying more laptops. Surely any old laptop would have served my portability needs. The last two Dell and HP-Compaq systems that I paid £750 and £500 for (respectively) would have been money better spent on a desktop. But that was when I moved around a lot and another laptop made sense to me… at the time.

So here it is, my most powerful machine… Rather crap for gaming. While i’m planning to get myself a real juiced-up desktop soon, I thought it would be fun to start squeezing this baby for all it’s worth.
