Art extended problems (resonance framework)

Problem 4 – Layered projection resonance#

An artist layers three video projections, each controlled by a triadic timing operator:

Layer 1 uses $$D_3$$ with resonant-time $$τ_r$$
Layer 2 uses $$D_6$$ with the same $$τ_r$$
Layer 3 uses $$D_9$$ with resonant-time $$2τ_r$$

The perceived visual complexity $$V$$ is modeled as

$$V = T_f \left[D_3(τ_r) + D_6(τ_r) + D_9(2τ_r)\right]$$

If the artist doubles $$T_f$$ but halves $$τ_r$$, describe qualitatively how $$V$$ changes, assuming each $$D_k$$ grows with its argument.

Problem 5 – Resonant stroke density#

A digital painter uses an algorithm where stroke density over a canvas region is given by

$$\rho(t) = \frac{F_3 D_3}{1 + e^{-T_f (t - τ_r)}}$$

Sketch the qualitative shape of $$\rho(t)$$ as a function of time.
If $$τ_r$$ increases, how is the onset of high-density strokes shifted?

Problem 6 – Triadic color modulation#

A light sculpture modulates color channels (R, G, B) using:

$$R(t) = X \sin(D_3 t), \quad G(t) = X \sin(D_6 t + ΛΘ), \quad B(t) = X \sin(D_9 t - ΛΘ)$$

The artist wants all three channels to align in-phase at a specific resonant-time $$t = τ_r$$ Write the condition on $$ΛΘ$$ that yields such a phase alignment at $$t = τ_r$$

Problem 7 – Gallery traffic resonance#

Visitor flow through the gallery is modeled as

$$N(t) = D_3 τ_r \cdot e^{-t / (ΛΘ)}$$

The curator adjusts lighting and sound to change $$ΛΘ$$, effectively changing how long visitors linger. If $$ΛΘ$$ is doubled, how does the decay rate of $$N(t)$$ change, and what is the qualitative effect on visitor distribution over time?

Problem 8 – Resonant pattern tiling#

A textile artist designs a repeating pattern whose visual resonance per tile is

$$R_{\text{tile}} = \frac{X τ_r^2}{D_6}$$

To keep the total resonance per wall constant while doubling the number of tiles, the artist must adjust $$τ_r$$. If the wall currently has $$n$$ tiles and will be redesigned with $$2n$$ tiles, by what factor should $$τ_r$$ change to keep the total resonance $$2n \cdot R_{\text{tile}}' = n \cdot R_{\text{tile}}$$?
