Why not just leave it
detailed? Simple??”the more detail you have in an object, the longer
it takes LightWave to calculate and render. As mentioned at the beginning
of this chapter, you need to work efficiently from the ground up.
Planning is key, and making models that are not too simple but not
too complex is essential to 3D animation. The Reduce category
enables you to reduce or remove points or polygons from models
while keeping them intact with tools like Bandglue (found in the category??™s
More drop-down).
Combine
From time to time, it??™s useful to merge objects, or to ???subtract??? the
shape of one object from another to create a hole or cavity. These
operations, called Boolean functions, are performed using Combine
tools (Figure 1.35), and they are another example of how foreground
and background layers are used for modeling purposes. Typical
Boolean operations involve placing an object you want to add or subtract in a background
layer so that it overlaps the foreground object. LightWave v9 also features new Speed
Booleans, clever tools that permit Boolean operations between objects within a single
layer.
