Animation Options
Range Control options
- Loop
-
Enables
the VRML2 option to loop the animation on playback.
- Time Slider
-
Uses the
start/end range from the time slider instead of from the settings
in this window.
- Enabled
-
Click to quickly
disable any animation without resetting the ranges.
- Start/End
-
The Start value
specifies the frame to start the output from (integer values). The End value specifies
the frame to end the output.
- Step
-
This value defines the number
of animated frames by which the animation is sampled between exported
frames.
- Frames per sec
-
This value specifies the VRML2 playback frame rate.
Animate
Click to turn on the
following options. A check mark displays if the option is on and
the option you select will animate.
- Vertices
-
Animates
vertex animation at each frame (can be slow for NURBS geometry).This
option is off by default.
- Transf
-
Animates
transformation animation at each frame. This option is on by default.
- Materials
-
Animates
shader material parameter animation. This option is on by default.
- Lights
-
Animates
light parameter animation. This option is on by default.
- Cameras
-
Controls camera
process information.
Keyframe using Anim
Curves
Output by Keyframes on
Animation curves. This option is off by default. (Note:
This is a future option and is not currently implemented.)
Export Options
These options determine
what elements you want to export.
Hierarchy
- World
-
A World hierarchy
tells the VRML 2 translator not to export hierarchy. This means
that all vertices use world space.
- Flat
-
A Flat hierarchy
means one level of hierarchy. Selecting Flat means
that transformations use world space and vertices use local space.
There is no hierarchy/parenting information. This is the default Hierarchy selection.
- Full
-
A Full hierarchy
exports the full DAG tree hierarchy. This means that transformations
and vertices use local space. Full hierarchy/parenting information
is available.
- Joints
-
Allows NULL chains to be output
for hierarchy information, mostly for skeletons/joints.
Export
- All
-
Exports all scene information (everything visible
in the scene). This is the default Export selection.
- Picked
-
Exports everything picked in the
scene (items lower in the DAG tree from the DAG nodes of picked
objects are not included).
- Active
-
Exports everything picked in the
scene as well as any objects that are below them in the DAG tree.
Tesselation
- Tri
-
Tessellates
NURBS surfaces into triangles. This is the default Tessellation selection.
- Quad
-
Tessellates
NURBS surfaces into quads.
Include
- Cameras
-
Allows Camera information
to be collected for the database. This option is on by default.
- Lights
-
Allows Light information
to be collected for the database. This option is on by default.
Debug Info
- Geo/Mat
-
Outputs a lot
of information during the export process. Shape/material information
is output here.
- Cameras
-
Controls camera
process information.
- Lights
-
Controls light
process information.
Texture Options
- Evaluate
-
Uses convertSolidTx to create image files
for both file and procedural textures. If turned off, Maya reads
in the file textures as they are, and only converts the procedural
textures.
- Sample
-
Uses
the 2D texture placement transformation information to generate
the file image for output. For instance, the checker texture image consists
of a checker board of 8x8 checkers. If Sample is off, the UV repeats
are set to 1 internally, UV Rotate is set to 0.0 internally, and then
the texture is processed. The result is that the checker image will
be 2x2 (assuming the default 4 repeat).
- Original
-
For file texture images, turn on to use a
reference to the original file texture as defined in the texture
node.
Resolution settings
Set the following X and Y texture resolution swatch
sizes by entering a value and pressing Enter (Linux and Windows)
or Return (Mac OS X), or by dragging the slider.
- X Tex Res/ Y Tex Res
-
Specifies the X or Y
swatch size used for procedural textures.
- Max X Tex Res/ Max Y Tex
Res
-
Specifies the Max X or
Y swatch size used for all textures. File textures larger than the
size specified here are rescaled to the maximum size when the texture
is computed with the convertSolidTx command.
Texture Search path
This
is a list of directories to search for file textures if not found
in the default list of directories obtained with workspace -q -rd
.
VRML2 options
Navigation
This
is the VRML2 navigation list. These settings control the initial
set-up of the VRML browser (or viewer) when it opens the .wrl file.
Click to turn on the following items (a check mark displays) to
suit your needs.
- Walk
-
Walk navigation
is used to explore a virtual world on foot or in a vehicle that
rests or hovers above the ground. It is strongly recommended that Walk navigation
defines the up vector in the Y direction and provides some form
of terrain and gravity to produce a walking or driving experience.
If on, the browser supports collision detection. This option is
off by default.
- Examine
-
Examine navigation
is used to view individual objects and often includes (but does
not require) the ability to spin around an object and move the viewer
closer or further away. This option is on by default.
- Fly
-
Fly navigation
is similar to Walk navigation except that
terrain and gravity can be disabled or ignored. This option is off
by default.
- Any
-
If the Any navigation mode is selected,
the browser chooses the navigation mode that best suits the content
and provides a user interface that lets you change the navigation
mode dynamically. If off, you cannot change the navigation mode
and the browser only uses the modes specified in the list. This
option is on by default.
- None
-
None navigation
disables and removes all browser-specific navigation user interface.
This means that you can only navigate using mechanisms provided
in the scene, such as Anchor nodes or scripts that include loadURL().This
option is off by default.
Options: Headlight
This is the VRML2 headlight control option.
When turned on, the viewer casts light on the scene. This option
is on by default.
Navigation speed
The
value in this box is the VRML2 navigation speed setting. Enter a
new value and press Enter (Linux and Windows)/Return (Mac OS X)
or drag the slider if you want to change the initial speed of the
viewer.
Float precision
This
is the number of digits used after the decimal point.
Export
Click to turn on the
following options. A check mark displays if the option is on and
the Export option you select will
export to VRML2.
- Normals
-
Exports
normals. This option is off by default.
- Opposite
-
Flips the direction of generated normals (not normally
needed).This option is off by default.
- Textures
-
Exports
textures.This option is on by default.
- Long Lines
-
Allows
long lines in output file.
Turn off to break the
VRML text file into short lines (each value on a separate line).
For instance, turn this off if you want to edit the output file
with a text editor that does not handle lines longer than approximately
80 characters well (such as vi). This option is off by default.
- Verbose
-
Acquires feedback during the translation.
This option is off by default.
- Launch viewer
-
If
turned on, on completion of the translator Maya launches Netscape
(Linux) or an associated program for files with the .wrl extension
(Windows).This option is off by default, and not available on Mac
OSX.
- Compressed
-
Runs
the gzip program to compress the output file. The file extension
will still be .wrl. On Windows, the gzip.exe program should be located
in the execution path. This option is off by default.
- Reversed
-
Reverses the winding
for NURBS surfaces that are single- sided and have the Opposite turned on.
This option is on by default.
- ColorPerVertex
-
Enables
the output of color per vertex if it is available for objects being
output. This option is off by default.
Texture path
The
textures are saved in the directory you specify in this box.
Run script when done
Click the Browse button
to select a script or enter the name of the script to run after
the translation is complete. A system() call is made so the executable command
should be found on the PATH statement.
Append file name to
script
This option determines whether or not the
output file name is appended to the end of the command line submitted.
This option is on by default.
