r operation

Syntax

• r(xAngle, yAngle, zAngle)
• r(center, xAngle, yAngle, zAngle)

Parameters

1. xAngle, yAngle, zAngle—float
   Angle in degrees to rotate about each axis.
2. center—selector
   • scopeOrgin—Default. Rotates around the scope origin (scope.t).
   • scopeCenter—Rotates around the scope center.

Description

The r operation rotates the current shape around the pivot-axes in xyz order (it adds the given angles to scope.r). If the rotation center is scopeCenter, it also updates scope.t to keep the center fixed.

Note:

r(x,y,z) is the same as rotate(rel,pivot,x,y,z)

Examples

Rotation centers

In this example, a mass model is split in vertical direction and the slices are rotated around the scope.t. Each slice's scope is shown, note how the y-axes denote an axis of symmetry. height = 18 dy = 2 Lot--> extrude(height) split(y) { dy : r(0, 360*split.index/split.total, 0) X }*
The same example as above, but this time the rotations are around the scope center. height = 18 dy = 2 Lot--> extrude(height) split(y) { dy : r(scopeCenter, 0, 360*split.index/split.total, 0) X }*
