javascript - calculation to arrange spheres in a ring -


i'm trying arrange 10 spheres in ring. calculation have put far, not working

            var bubblegeo = new three.spheregeometry(300, 20, 20);             var bubblemat = new three.meshlambertmaterial( { color: 0x888888 } );             var numbubbles = 10;             var bubblemesh;             var bubbles = [];             var startx = 0;             var starty = 500;             var spacing = 80 * math.sin( angle );             (var i=0; i<numbubbles; i++) {                 bubblemesh = new three.mesh(bubblegeo, bubblemat);                 console.log("bubble" + i);                 var angle = 360/numbubbles*i*math.pi/180;                 bubblemesh.position.set((startx + math.cos(angle)*bubbler) + spacing,                                          (starty + math.sin(angle)*bubbler) + spacing,                                          100                                         );                 scene.add(bubblemesh);                 bubbles.push(bubblemesh);             }

i don't know math. if folks there see have went wrong, appreicated. thanks!

            var bubbler = 400;             var bubblegeo = new three.spheregeometry(bubbler, 10, 10);             var bubblemat = new three.meshlambertmaterial( { color: 0x888888 } );             var numbubbles = 5;             var bubblemesh;             bubbles = [];             var startx = 1000;             var startz = 1000;             (var i=0; i<numbubbles; i++) {                 bubblemesh = new three.mesh(bubblegeo, bubblemat);                 var angle = 360/numbubbles*i*math.pi/180;                 bubblemesh.position.set((startx + math.sin(angle)*bubbler) * 2,                                           1000,                                           startz + (math.cos(angle)*bubbler) * 2                 );                 scene.add(bubblemesh);                 bubbles.push(bubblemesh);                    }

for reason, if add array scene after loop, doesn't work. wish in new three.group, position whole group, doesn't seem work @ moment either

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
