3D Objects
Using the Manipulators

Using the Manipulators

A 3D diamond being moved around the Viewport using Manipulators.

Use the Manipulators to quickly change your object's:

  • Position - to choose where your object is placed within the scene.
  • Scale - to make your object appear bigger or smaller.
  • Rotation - to rotate your object.

These are known as transformations. You can also edit these properties in the Inspector.

Using the Manipulators

The Manipulators are at the 3 icons at the top of the Viewport:

A screenshot from Spark AR Studio. The manipulator icons at the top of the screen have been highlighted.

Select the first icon to change an object's position, the second to rotate the object and the third to change the scale.

When you've selected an object and a Manipulator, you'll see axis or arrows appear on that object in the Viewport:

The Viewport is shown. Arrows have appeared, originating from the 3D diamond object.

Click and drag these axes, or the object itself, to transform the object.

In the example below, we selected a 3D object that looks like a diamond and clicked the first Manipulator icon - for position.

We then dragged the green axis to change the position of the object, moving it along the Y axis so it's no longer in the box:

The 3D diamond has been raised, as seen in the Viewport and Simulator.

You can also change the position or size of an object across all axes by clicking and dragging the yellow cube in the center of the object:

Or, click and drag the red, blue or green square to scale the object on 2 axes only.

If part of the manipulator is greyed out, it means you can't change that transformation for the object you've selected.

Local or Global coordinates

When an object is a child of another object, it can either be transformed:

  • In relation to its parent object's co-ordinates, which might not be the same as the Global co-ordinates - this is called Local.
  • Based on the fixed X, Y and Z axis - this is called Global.

In the the image on the left we've selected Global co-ordinates. On the right we've selected Local. The axis has changed, because the position is set based on where the object is positioned within its parent:

In the left example, the arrows point up and to the side at right angles relative to the scene. In the right example the arrows point up and to the side at right angles relative to the object's parents.

Pivot points

Choose Pivot or Center to switch between manipulating an object around its own pivot point, or a central pivot point.

You'd usually use this feature to transform multiple objects, either around their individual pivot points or a central point.
