Export VRML World File Dialog, File Options Tab

Sets the export file specifications.

Version The version of VRML (1.0 or 2.0) into which the design is converted.
Live3D Extensions Netscape's Live3D browser supports several extensions to the VRML 1.0 specification. This feature is for VRML 1.0 only.

If on, the VRML Publisher exports these extensions for background color, background image, and flashlight settings. The background image display feature may not be fully functional in some versions of Live3D, but should be completely supported in future versions.

Orthographic Cameras Orthographic (non-perspective) cameras are not completely supported in many VRML browsers. If on, non-perspective (camera setting off) views are exported as camera views with a small camera angle. This feature is for VRML 1.0 only.
Linear Geometry Most browsers support only surface and solid geometry and do not support linear geometry such as lines, arcs, line strings and open curves. If on, the Export Linear Geometry is exported as VRML “Indexed Line Sets.” If off, it is omitted.
Surface Normals Surface normals provide a VRML browser with information to more accurately display curved surfaces, particularly when smooth shading is used.

If on, the normals are included in the VRML file and the display of curved surfaces is greatly improved (however, the resulting file will be substantially larger).

Higher Order Surfaces VRML can export primatives such as sphere, cone and cylinder. This setting uses these primatives rather than stroking the elements out to triangles.
Drop Cells If off, VRML instancing is used for cells and shared cells. This essentially involves defining the cell geometry once only, and then referencing the definition for each cell occurrence. This significantly reduces the size of the VRML file but may not be fully supported by all browsers.
Drop Text If on, text is converted into a series of line elements rather than text letters.
Y Axis Up The navigation logic of some VRML browsers (such as CyberGate from Black Sun Interactive) expect VRML geometry to be oriented with the Y axis up, rather than the Z axis, as in Promis.e . If on, the Y Axis Up function rotates the geometry 90 degrees about the X axis, so that navigation works correctly with these browsers.
Indented Output If on, the VRML output file is generated with each "Separator" node indented by a single tab stop. This makes the file much easier to read, but can marginally increase the file size. Because browsers ignore tabs and other spacing, an unindented ASCII file is more difficult to read but is more compact and essentially identical.
Compress Output File If on, the output file is compressed as a "Gzip" compatible file. Although this can reduce the file size greatly, not all browsers can directly read compressed files. Live-3D automatically detects a compressed file with the .wrl extension, and decompresses it. Other browsers may only recognize compressed files with the .gz extension and may need to be configured for handling these files as VRML worlds.
Tolerance (pixels) The tolerance value specifies the maximum difference in screen pixels between a curved surface or polygon and the faceted approximation generated in the VRML file. The default value of .5 works well in most instances. A smaller tolerance value produces a more finely meshed but larger VRML file, while a large tolerance produces a more coarsely meshed, smaller file. Stroke tolerance values can range from .001 to 100.
Decimal Precision Decimal precision controls the number of decimal places generated for coordinate data in the VRML file. Larger values increase the precision of the coordinate data but increase the file size. Decimal precision values can range from 1 to 10.
