Perfect timing! I just got a new machine with a Quadro RTX4000 card, and I've been looking for example code to see what it can do.
It still blows my mind that Mandelbrot fractals (and now ray tracing) that would take 10s of minutes to render at 640x480 on my first computer, now render at 60fps on a 4k display with real-time panning/zooming.
- thdrdt 6y agoIt is true that hardware became very fast. But is also amazing raytrace algorithms improved over time. So both hardware and software make real-time raytracing possible. A very nice 'guide' for papers that make software improvements possible is the YouTube channel 2 minute papers.
- hyperpallium2 6y agoDon't Mandelbrot fractals take longer the more you zoom in, because more iterations are needed to distinguish detail? (IIRC correctly from when I played with implementing them)
- saagarjha 6y agoCould you "shortcut" it by taking advantage of the fractal nature?
- ChrisLomont 6y agoNot really. They’re self similar, not self identical, so determining detail takes increasingly more computation as you zoom in.
