Importing VRML Files 591

Co mpress numbers—

When on, trailing zeroes are

eliminated from decimal fractions. This makes

the exported file smaller without sacr i ficing any

precision, but can cause compatibility issues when

importing with certain programs. If you’re unable

VRML Files

Impor ting V RML Files

File menu > Import > Select File To Import dialog > Files

Of Type > VR M L (*.WRL, *.WRZ)

You can import VRML 1.0, VRBL, and VRML

2.0/VRML 97 files into 3ds Max. 3ds Max imports

geometry, materials (including diffuse texture

maps), lights, perspect ive cameras and view points,

transformations, and grouping nodes created by

other VRML tools. Once they are in the scene file,

you can edit, mod ify, and animate these objects.

3ds Max also imports basic transform animations,

such as position, rotation, and sca le. Also included

are animated color and light. These correspond to

the basic animation that is exported by t he VRML

1.0/VRBL and VRML97 exporters. Helper objects

are not created upon i mport. Lighting effects are

somewhat simplified from the full VRML lighting

model.

• VRML97 files don’t indicate the duration of

an animation. If you import animation from

aVRML97file,youmightwanttosetthe

animationlengthin3dsMaxmanually.

• More elaborate forms of animation

and simulation, including Script nodes,

MovieTexture nodes, and sensor nodes, are not

supported.

• The VRML 1.0 WWW Inline works only if the

URL refers to a local file residing in the same

folder as the .WRL file. Internet URLs are not

supported.

Interfa ce

Reset Scene—Deletes any existing scene upon

import. If you turn off this option, the imported

VRMLworldismergedintothe3dsMaxscene.

Turn to 3DS Coordinat es—Rotates the imported

VRML world from Y, which is "up" in VRML,

to Z, which is "up" in 3ds Max. If you turn off

thisoption,VRMLX,Y,andZcoordinatesare

imported without change.

Create Primitives—C onverts the VRML

Box/Cube, Cone, Cylinder, and Sphere nodes to

corresponding 3ds Max primitives, if possible. If

the V RML object has a texture on it, or if only

partoftheVRMLobjectistobecreated,ageneral

triangular mesh object will be created i nstead.

If you turn off this option, 3ds Max will convert

these objects to t riangular mesh objects.

Expor ting to V RML97

File menu > Export > Sele ct File To Expor t dialog > Save

As Type > VRML97 (*.WRL)

3ds Max scenes can be exported to VRML97 file

format.
