t

Syntax

  • t(tx, ty, tz)

Parameters

  1. txfloatAmount to translate in the x direction.
  2. tyfloatAmount to translate in the y direction.
  3. tzfloatAmount to translate in the z direction.

Description

The t operation translates the scope by the vector (tx, ty, tz), i.e. the vector is added to scope.t. If the scope rotation is non-zero, then the passed translation vector is rotated around the pivot first, with angles (scope.rx, scope.ry, scope.rz). In other words, the translation is relative to the scope axes.

The relative operator ‘ permits a convenient notation relative to the scope size: t(‘tx,0,0) is equivalent to t(tx*scope.sx, 0, 0).

Note: t(x,y,z) is the same as translate(rel, scope, x, y, z). 

Examples

Translate – rotation concatenation

This is the initial shape we start with. 
A--> primitiveCube()
Initial shape
First a translation of two units along the x-axis. 
A--> primitiveCube() t(2,0,0)
Translation of two units along x-axis
Then a rotation of 30 degrees around the y-axis. 
A--> primitiveCube() t(2,0,0) r(0,30,0)
Translation with rotation of 30 degrees around the y-axis
And another translation of 2 units along the x-axis.
Translations are along the scope’s x-axis, i.e. the rotation changes the global translation direction.The relative operator ‘ is used – here it does not make a difference because scope.sx is 1.
A--> primitiveCube() t(2,0,0) r(0,30,0) t('2,0,0)
translation of 2 units along the x-axis
