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 modifiers whose parameters can be animated.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. 7294 | Chapter 23 Managing Scenes and Projects
