t operation

Syntax

  • t(tx, ty, tz)

Parameters

  1. txfloat
    Amount to translate in the x direction.
  2. tyfloat
    Amount to translate in the y direction.
  3. tzfloat
    Amount 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).

This is the initial shape we start with.

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.
