Sample image of yaplot.
(Visualization of 3-dimensional bond percolation.)
Yaplot is an easy 3D modeller and animator for visualizing the results of computer simulation.
You can browse the motion of the 3 dimentional wire frame model with text labels and some marks on the cheap PC based X terminals.
Data format is simple and intuitive.
It can also open and render several files in windows at a time.
It is useful to watch spaciotemporal data.
It is the least beautiful and not durable for presentation, but enough quick and smooth for daily use. (Do not expect much to yaplot!)
Yaplot requires gtk.
First, get the source code and expand. On linux, compile them with the following commands.
prompt% ./configure prompt% make
If configure fails even when gtk is installed correctly, try the following.
prompt% aclocal prompt% autoconf prompt% ./configure prompt% make
When it is compiled successfully, install them to the appropriate places.
prompt# make install
On windows, edit Makefile.dos and try "make". Some features of yaplot are missing on Windows.
usage : yaplot [options] infile [infile ...] -e x,y,z Set the coordinate of the eye point. -l x,y,z Set the coordinate of the look point. -u x,y,z Set the up-vector. -c filename Specify palette file. -q n Specify n frames are cached in memory.(default=1) -d Debug mode. infile Yaplot command file.
Currently all options are unavailable on DOS.
Yaplot has the concept of layers. It has 12 layers by default. You can show/hide each layer by function keys.
When "-" is specified as the command file name, commands are read from standard input.
When multiple command files are specified, they are rendered in different windows. There are two modes of control, which are synchronous mode and asynchronous mode. When the mouse focuses to a windows in synchronous mode, your control (with mouse or keyboard) are reflected to all other windows. In asynchronous mode, on the other hand, your control are reflected only to the window where mouse is focusing.
You can alter modes by "s" key. All the windows are in synchronous mode by default.
If no command file is specified, help file is displayed.
By specifying "RECORD" option in Makefile, recording feature becomes available. When "r" key is pressed, hardcopies of the windows are saved in yaplotxx_yyyyy.gif(xx is window No.、yyyyy is frame No.) To stop recording, press "r" again.
If "u" is pressed, current view information (eye position, field of view, etc.) is saved in ".yapviewstack" file of the current directory. If "o" is pressed, last view information is recovered from ".yapviewstack" file. It is useful to share the view information on multiple yaplot. (This feature is not available on DOS)
When no palette file is specified, yaplot searches the palette file in the following order:
Several sample command files are included in source code package.
You can control yaplot by mouse and keys.
Key assignments are listed below.
Commands marked with "!" mark are "repeatable commands". Pressing number keys before repeatble command key makes the same effect as pressing the command key repeatedly. For example, pressing "5" "N" is the same as pressing "NNNNN" (animate in 5fps).
When you mistype the number, press ESC key to escape.
All the repeatable commands ( except "g" and "f" ) are relative, i.e., pressing "10N5P" is the same as "5N".
One line of the command files corresponds to one command. A command consists of a single command character followed by parameters separated by at least one space character, Any parameters are not omittable.
Each line of the palette file specifies the Red, Green and Blue intensity of the pallete. First line describes the color for palette 0. As the palettes 0 to 2 are reserved for system color (Black, Gray, and White), you should not modify them.
