r operation

Syntax

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

Parameters

1. xAngle—float
   Angle in degrees to rotate about x- axis.
2. yAngle—float
   Angle in degrees to rotate about y- axis.
3. zAngle—float
   Angle in degrees to rotate about each z- axis.
4. center—selector
   { scopeOrgin | scopeCenter }—The rotation center. scopeOrgin is the default. (used if no center selector is given).

Description

The r operation rotates the scope of the current shape around the pivot-axes in xyz order. The center of rotation is either the scopeOrigin(scope.t) of the current shape or the scopeCenter of the current shape.

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 }*
