You might want to take a look at "3D User Interfaces with Java 3D"
chapters 5 and 6, which discuss callouts/tooltips and visual attributes
for them in 3D, chapter 20, which describes how to construct a basic
callout from a transparent texture, and chapter 21, which describes how
to make the callout display-facing, constant-size, and display overlaid.
