Examples

Hyperbolic Spiral

X(t) = (100 * Cos(t * PI)) / t Y(t) = 0.0 Z(t) = (100 * Sin(t*PI)) / t t-Min = 1.0 t-Max = 5.0 Samples = 50

Epizycloide

X(t) = (90 +30) * Cos(t * PI) - 40 * Cos(((90 + 30) / 30) * t * PI) Y(t) = 0.0 Z(t) = (90 + 30) * Sin(t * PI) - 40 * Sin(((90 + 30) / 30) * t * PI) t-Min = 1.0 t-Max = 3.0 Samples = 65

Rect

X(t) = 100 * t Y(t) = 0.0 Z(t) = if(t % 1.0 > 0.5, 0.0, 100.0) t-Min = 0.0 t-Max = 5.0 Samples = 80
