Select a few polygons, for example, press q, and then give those panes of glass a
specific name and color. Deselect, then select some other panes, surface, color,
and so on. The Glass object in the Chapter 14 folder of this book??™s DVD has this
already done for you.
Exercise 14.3 Shattering Glass
This next exercise will shatter the glass window object built in the previous exercise. It is
similar to the earlier hard-body exercise, but with a few differences in settings.
1. Load the GlassWindow_Setup scene from this book??™s DVD.
This is a glass window,much like the one created in Exercise
14.2, with its surface polygons unwelded. The main difference
between this model and the window created in the previous
exercise is that it contains a white-to-blue background, which
won??™t appear until you render your scene.
The dynamic collisions that will shatter the window object
in this exercise require the window object??™s polygons to be
unwelded??”converted to discrete, self-contained polygons that
share no points or segments. Recall that we used the Unweld
command in Exercise 14.2 to separate the window??™s surface
polygons into ???shards??? that can be animated independently.
