Calibration of the 3D projector

Displaying the points in the projection

In the 3D Scenes panel, select the Pico Projector and ensure that the Show wire option is Enabled.

For a better view of the points in the projection, dim the master fader of the timeline currently displaying the pattern on the castle.

Remember the castle’s material is currently displaying the Render Surface.
If the timeline with the pattern is entirely faded out, the castle will be all black in the 3D Viewer panel because the associated Render Surface is not displaying any media.
You may chose to leave a little opacity on the timeline to see the castle better in the 3D Viewer.

Move your interface so as to display the 3D Viewer panel and the Warp panel simultaneously.

In the Warp panel, enable the 3D mode option:

In the V-Nodes panel select the proper Output and in the Editor panel open the 3D mapping subtab.

Enable the Display option.

Tick the next to the for all points options to blind all the points.

*Note: You must be in Show 2D mode for this option to be available. If you are in Show 3D mode click on the Show 2D button.

Select the first point in the list and unblind it with the button.

By default, all 2D points have a position of (0.0 ; 0.0) and are in the top left corner of the Warp panel.

Select the point and move it to align its position in the projection with the position of the corresponding point placed on the 3D model.

Repeat this operation for all the points previously created.

3D Projector calibration

Once all the points have been correctly placed in the projection, click on the button to compute the projector’s position.

Notice that the position of the projector in the 3D Scenes and 3D Viewer panels is automatically updated to reflect the computed projector’s position.

*Note: Take care that all the points are enabled when first computing the projector’s position.

Untick the Display option to remove the points from the output.

Now that the 3D projector is positioned relative to the 3D model the same way the projector is to the real model, we can directly output the 3D projector’s view from the 3D scene in our Output.

*Note: The ability to select/unselect points gives the user the possibility to re-calculate the 3D projector’s position while excluding certain points to obtain a more precise positioning.
The Live option enables to move a point’s position in the Warp panel and automatically adjust the 3D projector’s position to reflect the changes and make some minor tweaks in the projection.
These two options require to be viewing the projector’s view in the output first.

!Warning: When using the 3D mapping feature, take care to avoid any lenses on the projector that produce significant distortions in the image such as short throw or ultra-short throw lenses.
