|
[Purpose:]
|
|
|
|
VCR-style GUI for 3d interactive OpenGL visualization.
|
|
|
|
[Description:]
|
|
|
|
The vcr tool displays a GUI to do 3d interactive visualization of
|
|
LAMMPS snapshots or data files. It is a wrapper on the "gl"_gl.html
|
|
tool which draws the individual images in OpenGL windows
|
|
|
|
The vcr constructor creates the GUI. Note that multiple OpenGL
|
|
windows can be run by the same GUI so that multiple views of the same
|
|
data set can be manipulated simultaneously (or views of different data
|
|
sets so long as they have the same # of snapshots).
|
|
|
|
The view can be controlled by the GUI widgets or by invoking the tool
|
|
methods: play(), stop(), axis(), etc. The frame slider can be dragged
|
|
to view a desired frame. The mouse can also be used in the OpenGL
|
|
window to translage, rotate, or zoom the scene. The clipping sliders
|
|
or methods can be used to narrow the view of displayed data, though
|
|
their interactivity can be slow for scenes with lots of data.
|
|
|
|
The reload() method is needed if you change the selection attributes
|
|
of the underlying data assigned to the "gl"_gl.html tool, such as via
|
|
the "dump"_dump.html tool's methods. These changes will not be
|
|
visible in the OpenGL windows until the data is reloaded.
|
|
|
|
The save() method will save the current OpenGL window contents
|
|
to a PNG file. If multiple OpenGL windows are being used, multiple
|
|
files will be created. The save-all checkbox or method will store one
|
|
file per snapshot if the Play or Back buttons are used to start an
|
|
animation.
|
|
|
|
[Usage:]
|
|
|
|
v = vcr(gl1,gl2,...) start vcr GUI with one or more gl windows
|
|
v.add(gl) add a gl window to vcr GUI :pre
|
|
|
|
Actions (same as GUI widgets): :pre
|
|
|
|
v.first() go to first frame
|
|
v.prev() go to previous frame
|
|
v.back() play backwards from current frame to start
|
|
v.stop() stop on current frame
|
|
v.play() play from current frame to end
|
|
v.next() go to next frame
|
|
v.last() go to last frame :pre
|
|
|
|
v.frame(31) set frame slider
|
|
v.delay(0.4) set delay slider
|
|
v.q(5) set quality slider :pre
|
|
|
|
v.xaxis() view scene from x axis
|
|
v.yaxis() view scene from y axis
|
|
v.zaxis() view scene from z axis
|
|
v.box() toggle bounding box
|
|
v.axis() toggle display of xyz axes
|
|
v.norm() recenter and resize the view
