3D Parameters

To stay out of trouble, specify all the 3D parameters, even if you want to use what you think are the default values. It takes a little practice to learn what the default values really are. The best way to create a set of parameters is to use the [B] command on an image you like and then use an editor to modify the resulting parameter file.

3D=Yes or 3D=Overlay

Resets all 3d parameters to default values. If FILENAME= is given, forces a restore to be performed in 3D mode (handy when used with 'batch=yes' for batch-mode 3D images). If specified, 3D=Yes should come before any other 3d parameters on the command line or in a parameter file entry. The form 3D=Overlay is identical except that the previous graphics screen is not cleared, as with the [#] ([shift-3] on some keyboards) overlay command. Useful for building parameter files that use the 3D overlay feature.

The options below override the 3D defaults:

PREVIEW=yes

Turns on 3D 'preview' default mode

SHOWBOX=yes

Turns on 3D 'showbox' default mode

COARSE=nn

Sets Preview 'coarseness' default value

SPHERE=yes

Turns on spherical projection mode

STEREO=n

Selects the type of stereo image creation

RAY=nnn

selects raytrace output file format

BRIEF=yes

selects brief or verbose file for DKB output

USEGRAYSCALE=yes

use grayscale as depth instead of color number

INTEROCULAR=nn

Sets the interocular distance for stereo

CONVERGE=nn

Determines the overall image separation

CROP=nn/nn/nn/nn

Trims the edges off stereo pairs

BRIGHT=nn/nn

Compensates funny glasses filter parameters

LONGITUDE=nn/nn

Longitude minimum and maximum

LATITUDE=nn/nn

Latitude minimum and maximum

RADIUS=nn

Radius scale factor

ROTATION=nn[/nn[/nn]]

Rotation about x,y, and z axes

SCALEZYZ=nn/nn/nn

X,y,and z scale factors

ROUGHNESS=nn

Same as z scale factor

WATERLINE=nn

Colors nn and below will be "inside" color

FILLTYPE=nn

3D filltype

PERSPECTIVE=nn

Perspective distance

XYSHIFT=nn/nn

Shift image in x and y directions with perspective

LIGHTSOURCE=nn/nn/nn

Coordinates for light-source vector

SMOOTHING=nn

Smooths images in light-source fill modes

TRANSPARENT=min/max

Defines a range of colors to be treated as "transparent" when [#]Overlaying 3D images.

XYADJUST=nn/nn

This shifts the image in the x/y dir without perspective

Below are new commands as of version 14 that support Marc Reinig's terrain features.

RANDOMIZE=nnn (0 - 100)

This feature randomly varies the color of a pixel to near by colors. Useful to minimize map banding in 3d transformations. Usable with all FILLTYPES. 0 disables, max values is 7. Try 3 - 5.

AMBIENT=nnn (0 - 100)

Set the depth of the shadows when using full color and light source filltypes. "0" disables the function, higher values lower the contrast.

FULLCOLOR=yes

Valid with any light source FILLTYPE. Allows you to create a Targa-24 file which uses the color of the image being transformed or the map you select and shades it as you would see it in real life. Well, its better than B & W. A good map file to use is topo

HAZE=nnn (0 - 100)

Gives more realistic terrains by setting the amount of haze for distant objects when using full color in light source FILLTYPES. Works only in the "y" direction currently, so don't use it with much y rotation. Try "rotation=85/0/0". 0 disables.

LIGHTNAME=[filename]

The name of the Targa-24 file to be created when using full color with light source. Default is light001.tga. If overwrite=no (the default), the file name will be incremented until an unused filename is found. Background in this file will be sky blue.

MONITORWIDTH=[nnn]

This parameter allows you to specify the width in inches of the image on your monitor for the purpose of getting the correct stereo effect when viewing RDS images. See Random Dot Stereograms (RDS) .
