Inspector Workflow

An object can be duplicated in Inspector by creating either an instance or a copy of it. An instance will share the same transforms, geometry and materials of the original. Duplicating in this way conserves memory. Any change to one object (e.g. color) will change the other as well. A copy will have its own transforms, geometry, and materials. Twice the memory is used but changing the appearance of one will not affect the other.

For this exercise, we'll create a second instance of the Vizard logo. To follow along load the logo.osgb file found in the Vizard resources folder. The scene graph and model are shown below:

Create new transforms

First we'll create two transforms to hold the two logos. This will allow us apply transformations to the logos individually.

From the Create tab in the toolbar, select Transform.
Select the new transform in the scene graph to change it's name in the properties pane. Change the name to logo1:

Repeat the two steps above. Change the name of the second transform to logo2.

The scene graph is shown below:

Create an instance of the logo

Right click the logo.osgb transform in the scene graph and select Copy.
Right click the logo1 transform and select Paste Instance. There are now two identical logo objects listed in the scene graph. The two logos have the same position and orientation so only one logo is visible in the viewport.
Right click the logo.osgb transform directly under the Scene node and select Cut. Right click the logo2 transform and select Paste Instance.

The scene graph is shown below:

Position the logos

Select the logo1 transform and activate Translate mode. Set its X value to -1.0 using the type-in control in the toolbar.

Set the X value of the logo2 transform to 1.0. The two logos now appear side by side in the viewport:

Save the logos to a new file

Select File > Save As and name the file logos.osgb. The modified file can now be loaded in Vizard.
