ScanlineRender nodes
Reflection maps tend to be full panoramic images, usually 360 degrees. That's exactly
what you have in this imported panorama. It consists of 15 still frames shot on location
witha24-degreerotationfromframetoframe.Alltheseframesaresittingin3Dandform-
ing a rough circle, producing a 360-degree panorama.
However, this is only a panorama in the 3D world, not the 2D one. You need to convert
this into a 2D panorama for a reason explained later.
Nuke's ScanlineRender node usually outputs whatever the camera that's connected to it
sees, but its Projection Mode property's drop-down menu (which sets the type of output
mode) has other options. One of those is called Spherical, which is what you are after.
Let's connect a ScanlineRender node to the panorama. But first let's look at the panorama
in the 3D Viewer.
1. Double-click Scene2 (the Scene node at the end of the panorama script you just
brought in).
2. Hover your mouse pointer over the Viewer and press the Tab key to switch to the
3D Viewer. If you are already in the 3D Viewer, there's no need to do this.
3. Navigate back and up in the 3D Viewer by using the + and − keys and by holding
Alt/Option-drag. ( FIGURE 10.26 ) .
