t operation

Syntax

• t (tx, ty, tz)

Parameters

1. tx—float
   Amount to translate in the x direction.
2. ty—float
   Amount to translate in the y direction.
3. tz—float
   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).

Examples

Translate - rotation concatenation

This is the initial shape we start with. A--> primitiveCube()
First a translation of two units along the x-axis. A--> primitiveCube() t(2,0,0)
Then a rotation of 30 degrees around the y-axis. A--> primitiveCube() t(2,0,0) r(0,30,0)
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.
