📐Transforming Content

Learn how to move, scale, and rotate 3D content in Scene Viewer.

Moving 3D Content

Move the model by tapping the screen with one finger and moving the finger around the screen.

Scaling 3D Content

Using Touch Screen Gestures

Scale the model by pinching the screen with two fingers.

Using Metadata

You can use metadata to persistently transform 3D content.

If the content is too big or too small, go back to the console and add metadata to affect its transformation. After adding or changing metadata refresh the browser and relaunch the experiences for the changes to take effect.

The following keys are words the system uses as pre-defined metadata keys to control transformations:

Keyword	Type	Options	Effect
scale	float	Any positive number. Default value is 1.	Grows or shrinks the hologram uniformly

Refresh the browser and relaunch the experiences after adding metadata with WebAR experiences for the changes to take effect.

Rotating 3D Content

Using Touch Screen Gestures

Rotate the model by placing two fingers on the screen and moving them in a circular motion.

You can also use two thumbs and move them up and down, each thumb in the opposite direction.

Using Metadata

You can use metadata to persistently transform 3D content.

If you can add metadata to further adjust the starting rotation of the model. After adding or changing metadata refresh the browser and relaunch the experiences for the changes to take effect.

The following keys are words the system uses as pre-defined metadata keys to control transformations:

Keyword	Type	Options	Effect
xAngle	float	Any positive or negative number. Default value is 0.	Rotates the model on the x-axis
yAngle	float	Any positive or negative number. Default value is 0.	Rotates the model on the y-axis
zAngle	float	Any positive or negative number. Default value is 0.	Rotates the model on the z-axis

Remember to relaunch the experience after adding metadata with Scene Viewer experiences for the changes to take effect.

Adding Text to 3D Content

If you'd like to annotate the content, go back to the console and add metadata to add text. After adding metadata, relaunch the experience.

The following keys are words the system uses as pre-defined metadata keys to add and design text:

Keyword	Type	Options	Description
annotation<NAME>_content	string	Any string.	Text to appear with the 3D content
annotation<NAME>_position	float,float,float	Any triplet of positive or negative numbers.	Position of the text relative to the 3D content
annotation<NAME>_normal	float,float,float	Any triplet of positive or negative numbers.	Normal vector defining the "front" of text relative to the 3D content

For example:

Key	Value
annotationName1_content	Empire State
annotationName1_position	1,1,1
annotationName1_normal	-0.1,0.5,0

Remember to relaunch the experience after adding metadata with Scene Viewer experiences for the changes to take effect.

Can't see the text? The original size of the model might affect the annotations' coordinate system and displace the location of text. We recommend placing your annotations at 0,0,0 first and then fine tuning the coordinate of each axis.

Controlling 3D Animations

Controlling animations requires that you to upload pre-animated 3D assets that have a built-in animations list.

If you'd like to control built-in animations of the content, go back to the console and add metadata to control animations. After adding metadata, relaunch the experience.

The following keys are words the system uses as pre-defined metadata keys to control built-in animations:

Keyword	Type	Options	Description
autoplay	boolean	Either 'true' or 'false'. Default value 'true'.	Play the default animation automatically.
animationsTrigger	string	Either 'click' or 'after'. Default value 'click'.	Play the next animation by clicking the model or automatically after the previous animation.
animation<X>_name	string	Any string that matches a name of an existing built-in animation in the asset's pre-defined animations list.	The animation's place in the sequence of the animations that is presented.
animation_loop	boolean	Either 'true' or 'false'. Default value 'false'.	Play the animation once or in a loop. This option is available only if 'animationsTrigger' is not set to 'after'.

For example:

Key	Value
animation1_name	walking
animation2_name	running

Remember to relaunch the experience after adding metadata with Scene Viewer experiences for the changes to take effect.
