Discretization of the Beta-distribution of fiber orientation θ. The corresponding cumulative probability D(x) is given for each region. The span of Beta-distribution is Δ = 60°, and α = β = 6. The continuous cumulative probability D(x) is discretized by rounding method: D(x)= p(x+ h/2) − p(x−h/2), in which h is interval between regions.
