Snow Drift
| Drift speed X |
<0.01 px/frame |
MEDIUM |
Below 30fps resolution |
| Drift speed Y |
<0.01 px/frame |
MEDIUM |
Below 30fps resolution |
| Estimated speed |
<0.3 px/s |
LOW |
At 30fps, true speed may be higher |
| Drift direction |
None consistent |
HIGH |
No directional bias observed |
Interpretation: Snow particles are either static or
moving so slowly that motion falls below detection threshold at 30fps.
At 60fps capture (or on actual RG hardware), particle motion may be
visible.
