Hang on, measuring monitor refresh rate...

Explanation: The direction, α, of this camera's motion is in the interval [ π/4 + γ, π/2]. Our method therefore chooses the middle solution from the three below.

Left: always using the middle-left transition in Figure 9
Middle: always using the middle-right transition in Figure 9
Right: always selects tile pattern (bowtie/hourglass) randomly

Note: The left sequence shows a lot of flickering on, for instance, the bar. The right sequence shows less aliasing, but appears grainy due to the random patterns. These issues are much less prevalent in the middle sequence.

Desired frame rate:
