3D Venue

In the visualization area, the 3D VENUE displays the positions of all the virtual objects.

By default a Speaker is represented with its 3D model, whereas a Virtual Source is represented by default with a sphere.

Only the Mono, Stereo and Multichannel objects are represented in the 3D VENUE. They can be moved across and positioned directly in the 3D VENUE view: the spatialization algorithms rely on the position of the sources and the speakers to perform the automatic source panning.

Use the 3D Venue Options Bar to control the display options such as background opacity or object size.

Right-Click Menu

From a right-click in the 3D Venue, you can perform multiple tasks:

  • Add or remove sources or buses,
  • Change the Grid display options,
  • Select a transformation mode (see Objects Manipulation)
  • Open the 'Venue Parameters' window

Multiple Selection

To select multiple objects in the 3D VENUE, click and drag a selection box around the area containing the objects to select or hold down the ‘SHIFT’ key and click on the objects you want to select.

When editing the parameters of objects in a multiple selection, they will all be set to the same value.

The selected objects can also be moved together. To persistently move a selection of objects together and link their parameters, create a group in the Groups View.

Objects Manipulation

HOLOPHONIX offers a unique transformation tool, for advanced positioning options.

To position a Source or a Speaker in the 3D Venue, select it, then it can be positioned freely when placing the cursor at the center of the object.

Select an axis of the transformation tool to move the Source or Speaker only in that axis. Thanks to this tool, you can keep control of the source position, even if the 3D Venue is displayed with a 3D angle.

You can also move the source only in a specific plane: place your cursor on the square that is between axis, then move the source. For example, if you place your cursor on the square corresponding to the horizontal plane, when you move the source, only it X and Y or Azimuth and Distance coordinates will change. No elevation will be applied to the source.

From the right-click menu, you can choose multiple transformation modes, detailed below.

Transform Modes

Translation mode

This is the default transformation mode, described in this section.

Scaling mode

This transformation mode is only useful when multiple sources or speakers are selected. It allows changing the scaling of the selection.

Use the different axis to scale the multiple selection, or use the plane scaling by clicking on the square in between two axes.

Rotation mode

The rotation mode allows applying 3D rotations to a source (when the transformation reference is set to the center), or to a group of objects.

Use red, green and blue circles to move the sources or speakers along a specific rotation axis.

The external yellow circle applies a rotation in the display plane (controlled by the Venue Orientation). If you are set to the Top View, then the rotation will occur in the (x,y) plane. However, if you are set to the perspective vie or to any 3D-viewing angle, the yellow external circle will apply a diagonal, oblique rotation.

Transform references

From the right click menu, you can change the translation reference to the center of the selection ('Local'), or to the center of the venue ('Center').

For example:

  • To position a single source with the translation mode, set the transform reference to 'Local',
  • To apply a scaling to a multiple selection of sources, use the scaling mode with reference set to 'Local',
  • To apply a rotation around the venue to a source or a multiple selection of sources, use the rotation mode with the reference set to 'Center'.
