VRML world files

VRML world files can be read by JetStream Roamer.

Supported Entities

• All 3D geometry including cuboids, cylinders, cones, spheres, elevation grids, extrusions, face and line sets, and points.

• All grouping nodes - however some limitations exist on certain types of group node (see below).

Partially Supported Entities

• VRML2 Billboard nodes - children will be loaded but no billboarding will take place.

• VRML2 Collision nodes - children will be loaded but no specification of collision detection occurs.

• VRML1 WWWAnchor and VRML2 Anchor nodes - children will be loaded but any referenced VRML world will not be loaded upon clicking objects.

• VRML1 and VRML2 LOD nodes - the most detailed (i.e. first) child will always be loaded.

Unsupported Entities

• All ROUTE definitions.

• All sensor nodes.

• All interpolator nodes.

• Textures specified within the VRML file (VRML2 PixelTexture nodes and the image component of VRML1 Texture2 nodes).

• VRML2 Script nodes.

• VRML2 MovieTexture nodes.

• VRML2 Fog nodes.

• VRML2 AudioClip and Sound nodes.

• All text-related nodes (VRML1 AsciiText and VRML2 Text nodes, and FontStyle nodes).

VRML File Reader Options

Setting the VRML file reader options

1. Go to Tools, Global Options, VRML

   The VRML options dialog is displayed

   

2. Select the Default Units dropdown combo box to alter the default units for any loaded VRML world.

3. Check the Override Normals check box if you want to override any provided normals and force auto-generation within JetStream Roamer.

4. Check the Override Orientation check box if you want to override any specified orientation of vertices and force all to be assumed to be counter-clockwise.

5. Check the Override Switch Statements check box if you want to override the standard behaviour of switch statements. Often VRML authors will use switch statements to contain geometry selectable by scripts. Since Navisworks has no support for scripting, this option will allow some aspect of that geometry to be exposed, although results are unlikely to be precisely as the author intended.

6. Click OK to set these options or Cancel to exit the dialog without setting them.
