Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Function torus computes the X, Y and Z arrays to visualize a torus with model Torus. The left image below shows a torus with ri=0.5 m and ro = 0.2 m. The right images below shows the torus with the additional parameter settings:

opening    =   45 degree
startAngle = -135 degree
stopAngle  =  135 degree

Syntax

(X, Y, Z, C) = torus(nu, nv, multiColoredSurface, ri, ro, opening, startAngle, stopAngle)
