The effect happens in a real room with a strobe light going, but that's the same phenonemon - low persistence. It also happens in other virtual settings with lower contrast and brighter overall illumination (although it's less pronounced), so it's not just a matter of a dark environment and bright lines. It doesn't happen in the exact same virtual Tron-like room if persistence is set to full, and it's reduced at half persistence. So it does appear to be an artifact of low persistence.
- mdrejhon 13y agoYes, this effect shows up when you view http://www.testufo.com/#test=eyetracking http://www.testufo.com/#test=eyetracking on a CRT, then again on a common LCD. If you're running "ToastyX Strobelight" (easy lightboost programming utility) on a 120Hz LightBoost-compatible monitor -- hit Control+Alt+Plus to enable LightBoost strobing, then Control+Alt+Minus to disable LightBoost strobing. Control+Alt+1 will program the strobing to 1.4 milliseconds, while Control+Alt+0 will program the strobing to 2.4 milliseconds (oscilloscope measurements). The 1.4ms-vs-2.4ms is actually noticeable in the castle at the top of http://www.testufo.com/#test=photo&pps=1440 http://www.testufo.com/#test=photo&pps=1440 It's a very interesting exercise in hacking LightBoost 2D as a programmable-persistence computer monitor (100% software hack; no hardware modifications needed; no 3D kit needed)
