Pr ocedur es
To create V R ML97 files:
1.
Create the objects that ma ke up the scene.
2. IntheCreatepanel,chooseHelpers.

The VRML97 exporter suppor ts the following:
Lights—All VRML97 lig ht types: direct, omni, and
spot.
Cam eras—Free and t argeted cameras.
Primitives—Sphere, cone, box, and cylinder
primitive objects. These objects export as
VRML97 primitive objects. This helps reduce the
size of VRML97 files.
Animation—All position, rotation, a nd scale
animation on objects, as well as animated
hierarchies, inv erse kinematics, and all controller
types. Select
Coordinate Interpolators (page

VRML97 Tips
The following tips will help you make your work
look as good as possible and display and move as
fast as possible.
Geometr y
Use sma ll texture maps, and use them spar ingly.
Keep the poly gon count of your ob je c ts down
to achieve good per formance. Acompletescene
w ith a maximum of 5,000 to 10,000 polygons is
manageable for most computers. The
Level of
Detail (page 3–651)
helper lets you manage the
polygon count of objects in the scene. You can also
use the software’s Optimize modifier to simplify
objects before exporting them to VRML97.
