Exercising the GPU

I’m currently torturing the GeForce FX 5650GO card in my laptop with something it is not used to. As exam project for a course I am implementing a ray tracer almost entirely on the GPU and after several days of on-and-off work I have finally produced my first proper screenshot: I am using the technique described by Timothy Purcell in his Ph.D. dissertation from March 2004. To produce the screenshot I use 32MiB videoram in 13 32bit floating point textures and has a grand total of 14 Cg programs loaded. Nearly 500 lines of Cg code are used. Many of these numbers would be significantly reduced on a pixel shader model 3.0 card (the GeForce 6800 to name one), and I could really need multiple render targets, but hey, that is life.On other “news” I returned to Ã…rhus yesterday from my 9 days stay at my parents. My dad and sister gave me a lift and we ended up in IKEA where I bough a new bookcase which I assembled in the evening, now all I need is to fill it with all my books and junk.
