3d - java.lang.NoClassDefFoundError: javax/media/opengl/GLException at processing.opengl.PGraphicsOpenGL -


i writing program in processing on raspberrypi(raspbian), import 3d stl image file. working on microsoft (windows7) & linux(ubuntu) platform struggling run same program on raspberrypi (raspbian) platform.

i getting below error @ size(600,600,p3d) when run program on raspberrypi...

coding

import toxi.geom.*; import toxi.geom.mesh.*; import toxi.processing.*; trianglemesh mesh; toxiclibssupport gfx; void setup() {   size(600,600,p3d);   mesh=(trianglemesh)new stlreader().loadbinary(sketchpath("check.stl"),stlreader.trianglemesh);   gfx=new toxiclibssupport(this); }  void draw() {   background(51);   lights();   translate(width/2,height/2,0);   rotatex(mousey*0.01);   rotatey(mousex*0.01);   gfx.origin(new vec3d(),200);   nostroke();   gfx.mesh(mesh,false,10); }

error

the issue processing there no 3d implementation because raspberry pi needs opengl_es renderer. can render in 2d (e.g. size(200,200,java2d);).

there opengl_es renderer in processing it's android mode , has dependencies on android sdk. far know, there isn't processing opengl_es renderer can use on raspberry pi @ moment(if knows of one, please let me know). in theory how ever, should possible strip out android dependencies android pgraphics class, feels risky move (especially if have tight deadline).to started may want egl in java running on rasperry pi.

i recommend using openframeworks instead in case, if displaying stl file need. i've modified existing stl addon openframworks , tested it: performance great on raspberry pi. although it's c++, project inspired processing , lot of functions sound familiar.

once setup openframworks can download ofxstlmodel , compile example(i've updated run on raspberry pi). press key toggle wireframe view.

update there experimental raspian image including processing 3 3d support. check out this thread

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
