10.1.2 Projector selection and edit
As discussed previously, the base action for inserting a cue was taken to be:
click on a projector to select it, and click on a 2D interface to change a parameter.
Thus, selection of a projector by clicking is the primary means of projector interaction
accounted for in this version of the user site. It chiefly relies on the 2D Picking BB in
Virtools to determine whether the mouse pointer of the user is hovered over a
projector. If that is the case, a left click on the mouse selects the projector. Multiple
projector selections are handled by holding shift on the keyboard, and clicking on a
different projector. An “empty” click cancels a projector selection (deselects) – and an
empty click in this context, is defined as a click anywhere in the 3D view, which is not
on an area covered by a 2D interface element, and is not a projector model.
To follow the different stages in this process, the following indication is
implemented:
- Mouse hover over a projector – 3D model, representing a green
rotating circular curve appears, surrounding the projector (hereafter
called “selector”) – lasts as long as the hover
- Projector selected – a selector representing a white curve appears, along
with text in 3D, aligned towards the user. At the same time, the
projector edit panel (hereafter called “right”) appears, either in
collapsed or expanded state.
