Generate group
Turning on any of these options increases the size of the VRML97 file generated
by the export process.
Normals Generates real normals for objects. Some browsers need normals
to do smoothing properly. Check this box if you are exporting geometry that
uses smoothing groups in 3ds Max, to see the correct shading. Default=off.
Coordinate Interpolators Exports animation effects that involve actual
modifications of the mesh objects, and not just move, rotate, and scale.
Examples include the Taper, Bend, and Twist modifiers, and space warps. This
option can generate large files, because the exporter has to calculate the
position of every vertex for this kind of animation.
If your animations aren't exporting correctly, try exporting with this option
chosen. An example of animation motion requiring Coordinate Interpolators
is a stick figure made up of simple rectangular boxes that have bones Linked
to the boxes as a skeleton. Even though these boxes move through space
without any noticeable shape morphing, their motion will not be exported
without the use of Coordinate Interpolators, because their motion isn't derived
from simple transforms. Any animation achieved using the modifier stack or
object parameters needs Coordinate Interpolators. This includes animated
XForm modifiers.
Certain types of animations are not possible with Coordinate Interpolators;
for example, when the mesh being animated changes size between frames.
An example of this is animating the number of segments in a sphere. 3ds Max
warns you if it detects this type of animation on export.
Indentation Indents the VRML97 source code so it is easy to read. Default=on.
Export Hidden Objects Exports hidden objects. Default=off.
Primitives Exports VRML97 primitives, which reduces the file size because
these primitives are described very simply (for example, a sphere is described
by its radius). To see how many polygons are in the scene, turn off this box
to export 3ds Max primitives, which have an indexed face set for each object.
Default=on.
Flip-Book Exports the scene to multiple files. The sample rate is set in the
in the Flip-Book section of the Sample Rates dialog. The file name you specify
becomes the base for the sequence of files. For example, if you specify the file
name test.wrl, choose one file per animation frame, and have five frames, 3ds
Max exports the following:
test.txt contains general info, start/stop times, and number of frames.
