===== 3D model =====

vrdoro enables the combination of 360-degree panoramas with 3D models and VR spots. This allows interactive three-dimensional virtual worlds to be modelled.

A 3D model can be placed in a VR room and then blends seamlessly into the panoramic image for the viewer. 3D models can optionally be activated in the view and then controlled.

==== Activate 3D model ====

If a 3D model can be activated, it can be clicked on by the viewer and brought into focus. The user can then rotate and scale the model. Activated elements are located in an activation sphere, which can be seen in the image as a green semi-transparent sphere around the model.

During activation, the model can be interacted with using the controls. The model can ...
  * closer or further: Use the scroll wheel of the mouse or a pinch gesture
  * be rotated:
    * Grab the model near the centre and move it in one direction (click-and-drag). This rotates the model around the X and Y axes.
    * If you hold down the CTRL and SHIFT keys at the same time, you can rotate the model around the axis pointing towards you (Z axis).
  * can be moved: To do this, grab the model with the right mouse button.

For touch displays, the corresponding gestures supported by the device apply.
