1. Having added a light to the scene (see Adding lights to the scene, double click on it, or right click and
choose Edit... from the context menu, to open the Light Editor, (see Section 26.4, “ Editing Lights ”).
2. Point, distant, spot and projector lights have a Location parameter. Distant and spot lights
additionally have a To parameter. You can type in x-, y-, and z- coordinates for these, or alternatively
use the Pick button to interactively pick a point in the scene where the light and/or target is located.
The light is represented by a 3D wireframe sun icon in the scene and the target by a wireframe
sphere. The currently selected light is drawn in the selection color (see the section called "Selection
Options" in chapter called "Selecting Items" in the Roamer book for more information on this).
Note
JetStream does not allow you to pick a point in empty space so you must pick a point on the
model.
3. Lights can be positioned interactively. The 3D wireframe sun icon, representing the light, has six bars
extending out along the x- axis, y- axis and z- axis. Hover the mouse cursor over one of the bars. The
cursor will change to a hand and the bars will extend further along that axis. Hold the left mouse
button down to hold on to the light and move it in either direction, along the extended bar. Release
the left mouse button to release the light in its new position. This can be performed for all three axis.
4. Lights can also be positioned in the current location of the camera, which can be anywhere in the
scene. Navigate to the location where you wish the light to be positioned. Right click on the light in
the palette (right hand pane of the Lighting tab) and choose Position as Camera from the context
menu.
Note
Not only will this position the light in the same location as the camera, if the light has a To
parameter, this will also be set to the focal (or Look At) point of the camera.
