VRML (.vrml, .wrl) Import/Export

VRML (Virtual Reality Modeling Language) is a standard file format for representing 3-D interactive vector graphics, designed particularly with the World Wide Web in mind. It has been superseded by X3D.

Import

To open, import, insert, and attach a file as a worksession

1. From the File menu, click Open or Import.
2. In the Open dialog box, select the supported file type.
3. If the import can be configured, click Options to specify import settings.
4. Click Open, or press Enter.

Note: When Rhino opens a non-3dm model, the title bar reflects the name of the model that was opened. When the model is saved for the first time, this model name is entered as the file name.

Note

● Only VRML 2 files can be imported.
● Spotlights, point lights and directional lights import.

Export

另存或导出 Rhino 模型

1. 从文件功能表选择导出选取的物件或另存文件。
2. 在弹出的对话框的文件类型栏位清单会列出可以导出的文件类型。
3. 在文件类型栏位选择文件类型。
4. 在文件名称栏位输入文件名称。
5. 设定保存的方式。

最小化保存

清除渲染、分析网格虽然可以让文件变小，但下次打开该文件时需要较多的时间重新计算渲染网格。

仅储存几何图形

只储存几何物件，不储存图层、材质、属性、附注与单位设定。

这个选项和导出物件很类似，使用这个选项储存时必需另存文件，储存的文件也不会成为目前 Rhino 打开的文件。

Save Textures

Embeds external textures used by materials, environments and decals into the model.

6. 如果导出的文件类型有选项设定，可以按选项按钮做设定。
7. 如果导出的文件类型只能储存网格物件时，会弹出将 NURBS 转换为网格的网格转换设定对话框。

VRML Export Options

Version

Try 2.0 first. If it does not work with your VRML viewer, try 1.0.

1.0

2.0

Options

Vertex normals

Only the polygon mesh vertex normals calculated from the NURBS surfaces export to the VRML file. This may improve the appearance of the objects in the viewer, and it will make the file much larger.

Texture coordinates

The uv texture mapping coordinates are exported to the VRML file.

Vertex colors

In order to get vertex colors to export select a mesh with vertex colors such as a mesh imported from VRML or an mesh with the ExtractAnalysisMesh command.

Always use these settings. Do not show this dialog again.

Saves the current settings and turns off the dialog display.

恢复弹出设定对话框

4 Click Options in the appropriate Save, Export, Open, Import, or Insert dialog box.

Note

● The default Top view is exported.
● Render color, shine, and transparency determine the render material properties exported to the VRML file.
● The render background color exports as a background color to VMRL2.
● Spotlights, point lights and directional lights export.
● Material names assigned to objects in Material Properties export.
● Some VRML clients are incompatible with the material shininess (specularity) set to zero. Using Cortona and Cosmo Player, objects with shininess set to zero shade completely white. If the shininess is zero, Rhino sets the shininess to something bigger than zero (we used 1, but the value does not matter) and the specular color to black. The Black specular color results in a matte surface in the VRML viewer.
● Texture assignments are not exported.
