Spectral path tracing on Vulkan: prisms, lenses, caustics, dispersion.
What happens
Spectral path tracing on Vulkan: prisms, lenses, caustics, dispersion. Geometric optics with ideal smooth surfaces. Glass absorption follows path length; optical solids must not overlap.
Equations used in the module
Equations n₁ sin θ₁ = n₂ sin θ₂; R = (R_s+R_p)/2 n(λ) = 1.510 + k·0.00420/λ²; λ [μm] T(d) = exp(−σ_a d) = T(1)^d T(d₁+d₂) = T(d₁)T(d₂) f = ρ/π
