ldglite − Display (LEGO) brick models

ldglite [ −xpq ] [ −aorientation ] [ −eoffset ] [ −fh ] [ −fs ] [ −itype ] [ −lparser ] [ −mmode ] [ −ox,y ] [ −ux,y ] [ −vsize ] [ −wwidth ] file ... | --

ldglite reads a file (or standard input if ‘‘−−’’ is specified) containing a (LEGO) brick model i LDRAW DAT format and displays the model.

ldglite takes the following options

−aorientation

Nine comma-separated floating point numbers, which make up a matrix used for scaling and rotating the presented model. The default is <1,0,1,0.5,1,-0.5,-1,0,1>.

−eoffset

Fixes polyline offset driver errors. Try -e0.95 if lines look bad.

−fh

Turns on shading mode.

−fs

Turns off stud drawing. (l3glite only)

−isize

Picks output image type.

1 for PNG.
2 for transparent PNG.
3 for BMP8.
4 for BMP24.
5 for PPM.
Prefix the number with a − to turn off cropping.

−lparser

Select parser, use d for the ldlite parser, or 3 for the l3 parser. e starts the program in LEDIT emulation mode, E starts the program in LEDIT emulation mode with soild moving pieces. −ledit or -LEDIT do the same but with draw-to-current and stud-as-line on.

−mmode

Picks operation mode.

p for pause at each step.
c for continous rendering of the whole model.
s for save an image of each step.
S for save an image of each step with off-screen rendering.
The default is p.

−ox,y

Changes the centre of the picture. The value for <x> moves across and the value for <y> moves down.

−p

Turns on polling mode.

−q

Quality lines (antialiased)

−ux,y

Saves a huge output image from window sized tiles. (see notes below)

−vsize

Picks the window size.

-2 for fullscreen gamemode (no menus).
-1 for fullscreen with no decorations.
0 for 320×200 pixels.
1 for 640×200 pixels.
2 for 640×350 pixels.
3 for 640×480 pixels.
4 for 800×600 pixels.
5 for 1024×768 pixels.
6 for 1600×1200 pixels (should only be 1280×1024).
The default is a full-screen window.

−wwidth

Set line width.

−x

Displays the x,y,z axis.

You should set the environment variable LDRAWDIR to a directory containing the basic ldraw files.

A click on the right mouse button gives a menu.

Use -uX,Y on the command line to build and save an image larger than the screen made out of several tiles, each the size of the ldglite window. This can be used in combination with the -w option for wide lines and/or the -q switch for antialiased lines to generate high quality instructions. Currently this dumps PPM files instead of BMP files. PNG works, but transparent backgrounds and cropping are not supported in tiled mode. Ldglite automatically exits after saving the images (much like the -MS mode). The following command renders the model in double size and saves a 2000 by 2000 PNG file. It uses the l3 parser so it only has to parse the mpd file once for the multiple rendering passes required for the tiles.
