Example – Display Spotlight Data

By

This scene shows how ICE can be used to display custom information about aspects of a scene. In this case, the cone of a spotlight is displayed, with an option to display a projection of the spotlight on the surface of geometry. A second example shows how the same setup can be used for a near and far attenuation display.

One great thing about ICE is how easy it is to re-use and re-task your “code.” In this example, it is simple to save the null containing the ICE operator as a model. Any time you need this display, import the model and give it your spotlight’s name, and you’re done. Or better, write a script which does this for you so all you have to do is pick the light. – AM

Update

Petr Zloty sent me a useful tip… when you place the ICE operator on an empty pointcloud rather than a null, the results display properly in any viewport. This is an important realization which is really good to know. In fact, the problem with ICE display attributes on nulls only appearing with wireframes is an annoyance which I’ve bumped against more than once. Thanks Petr!

Thanks Petr for the tip and the screenshot!
