140 Chapter 4 Using Proxies
You can combine this setting with the useProxy setting if the script you’re creating is
exceptionally slow to render. For example, setting useProxy to P1 lowers the overall
processing resolution to 1/2 by default. If you set the interactiveScale setting to 1/4,
parameter interactivity will be very fast, and you won’t have so long to wait when you
release the parameter control to let the image render at the current proxy setting.
The following is an example of how to use the interactiveScale parameter:
1 To follow along, use a FileIn node to read in the saint_fg.1-5# file, located in the $HOME/
nreal/Tutorial_Media/Tutorial_05/images directory.
2 Apply a Filter–RBlur (not Blur or IBlur).
3 Set your oRadius to approximately 300 (note the very slow RBlur).
4 Open the Globals tab, then set the interactiveScale to 1/3.
5 In the Viewer, drag the center control around. Notice that the image drops to a
temporary lower resolution while you make this adjustment. When you release the
mouse button, the Viewer image returns to its original resolution.
