Hang on, measuring monitor refresh rate...

Explanation: The direction, α, of this camera's motion is in the interval [0, π/4 - γ]. Our method therefore chooses the left-most 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 middle sequence shows a lot of aliasing in the shadow. The right sequence shows less aliasing, but appears grainy due to the random patterns. Neither of these issues are present in the left-most sequence.

Desired frame rate:
