convert function

Syntax

float convert(coordinate, fromSystem, toSystem, type, x, y, z)

float[] convert(fromSystem, toSystem, type, coordinates)

Parameters

• coordinate (selector)

  x, y, z

  Coordinate component to convert.

• fromSystem (selector)

  scope, pivot, object, world

  Coordinate system from which to convert.

• toSystem (selector)

  scope, pivot, object, world

  Coordinate system to which to convert.

• type (selector)

  pos, orient

  Choose interpretation of the coordinates array or the (x, y, z) tuple as coordinates or angles.

• x, y, z (float)
  coordinates (float[])
  Position (coordinates) or orientation (angles in degrees) in the fromSystem to convert to the toSystem.

Returns

The selected coordinate component of the tuple (x, y, z) or the coordinates array, converted from the fromSystem coordinate system to the toSystem coordinate system. The coordinates can either describe angles or a position.

Description

The convert function converts positions and orientations between different coordinate systems.

Example

Init --> extrude(3) t('0.2, 0, '0.7) s('0.5, '1, '0.5) r(-10, 70, 0) // position of scope origin in world coordinates print(convert(scope, world, pos, [0,0,0])) // (3)[1.0452611297369,0,2.183733612298965] // x-position of scope origin in world coordinates print(convert(x, scope, world, pos, 0, 0, 0)) // 1.0452611297369 // position of scope origin in pivot coordinates print(convert(scope, pivot, pos, [0,0,0])) // (3)[0.3999996185302735,0,-0.6000001430511476] // orientation of scope origin relative to world axes print(convert(scope, world, orient, [0,0,0])) //(3)[-10,23.45978546142578,0] // position of scope center in world coordinates print(convert(scope, world, pos, [scope.sx/2,scope.sy/2,scope.sz/2]))
