NAME

vars - With no arguments, will list all the MGED variables and their values.

CONTENTS

SYNOPSIS

vars [variable=value]

DESCRIPTION

With no arguments, will list all the MGED variables and their values. If a variable=value string is included on the command line, then that value is assigned to the specified variable. Note that no spaces are allowed around the “=”. The available variables are as follows:

o

o autosize -- if nonzero, then MGED will set the view size whenever it draws to an empty display.

o

o rateknobs -- if nonzero, then the knobs and sliders act as rate adjustments; otherwise, they act as absolute adjustments.

o

o sliders -- if nonzero, the sliders are displayed.

o

o faceplate -- if nonzero, the MGED faceplate is displayed.

o

o orig_gui -- if nonzero, the “viewing” menu is displayed.

o

o linewidth -- indicates how wide to draw lines.

o

o linestyle -- set line style of wireframe shapes. Currently not being used.

o

o hot_key -- the X11 keysym definition for the key to toggle the send_key value. The default is “0xFFC6” (65478 decimal), which is the F9 key. The keysym values are defined in the X11 file named keysymdef.h.

o

o context -- if nonzero (the default), then primitive editing parameters entered via the p command will be applied to the edited shape in the context of the combination tree above it in the displayed hierarchy. This means, for example, a translation applied to a shape will translate the shape to some point such that when the transformation matrices for that path are applied, the edited shape will appear at the specified location. If context is set to zero, then the primitive edit operations will be applied directly to the edited shape. This means that a translation to a specific point may result in the edited shape being drawn at a point different from that specified (due to transformations in the combination tree above it). Note that this only affects primitive edit operations that use the p command.

o

o dlist -- if nonzero, use display lists.

o

o use_air -- if nonzero, use air while raytracing.

o

o listen -- if nonzero, listen for connections to MGED’s built-in fbserv.

o

o port -- port for the built-in fbserv to use.

o

o fb -- if nonzero, then framebuffer is active.

o

o fb_all -- if nonzero, use entire geometry window for the framebuffer; otherwise, use only the rectangular area.

o

o fb_overlay -- if nonzero, overlay framebuffer image over geometry; otherwise, draw geometry over the framebuffer image.

o

o mouse_behavior -- see the following list of mouse behaviors:

  o

o c -- fire ray for combination edit selection.

  o

o d -- default behavior (i.e., as found in classic MGED).

  o

o m -- fire ray for matrix edit selection.

  o

o p -- paint rectangular area.

  o

o q -- fire query rays.

  o

o r -- raytrace rectangular area.

  o

o s -- fire ray for primitive edit selection.

  o

o z -- zoom rectangular area.

o

o coords -- see the following list of coordinate systems to use for transformations:

  o

o m -- model coordinates.

  o

o v -- view coordinates.

  o

o o -- object coordinates.

o

o rotate_about -- see the following list of centers of rotation:

  o

o v -- view center.

  o

o e -- eye.

  o

o m -- model origin.

  o

o k -- keypoint.

o

o transform -- see the following list of things to transform:

  o

o a -- transform the angle distance cursor if active; otherwise same as v.

  o

o e -- apply transformations to the edit.

  o

o v -- apply transformations to the view.

o

o predictor -- if nonzero, the predictor frame will be displayed.

o

o predictor_advance -- the number of seconds into the future to advance the predictor frame.

o

o predictor_length -- not currently used.

o

o perspective -- if greater than zero, this is the perspective angle in degrees; otherwise, perspective is turned off.

o

o perspective_mode -- if nonzero, turn perspective on; otherwise, turn it off.

o

o toggle_perspective -- used to toggle among the four canned perspective angles (i.e., 30, 45, 60, and 90).

o

o nmg_eu_dist -- when the -u option to the ev command is used, the NMG edgeuses are drawn this distance (mm) away from the actual edge.

o

o eye_sep_dist -- if greater than zero, this is the eye separation distance (mm) for stereo viewing; otherwise, stereo is off.

o

o union_op -- not currently used.

o

o intersection_op -- not currently used.

o

o difference_op -- not currently used.

EXAMPLES

The example shows the use of the vars command with an argument.

Example 1. Display the sliders.

mged>vars sliders=1

Turns on the sliders.
