remove part of iso_surface in mayavi -


i trying find hints in documentation of mayavi without success.

in visualization of complex data remove part of computed iso_surface. e.g., have code 

field =  mlab.pipeline.gaussian_splatter(data) iso = mlab.pipeline.iso_surface(field, contours=[0.07])

i may remove part of iso_surface explicitly explaining data limited along x, y or z doing 

field.filter.model_bounds = array([-1.,  1., -1.,  1., -1., 1.])

but can not find way explain arbitrary directed plane. instance, limit data (1,1,1) direction.

is there way this?

you can use data_set_clipper clip data. clipper either interactive or non interactive. demonstrate non interactive version:

fld = mlab.pipeline.scalar_field(data) clip = mlab.pipeline.data_set_clipper(fld) clip.widget.widget_mode='implicitplane' clip.widget.widget.enabled=0 clip.widget.widget.normal=(1,1,1) clip.widget.widget.origin=(20,20,20) #(0,0,0) not centre corner iso = mlab.pipeline.iso_surface(clip, contours=[0.07])

if want clip more have put clipped data data_set_clippe:

clip2=mlab.pipeline.data_set_clipper(clip)

however, not satisfied approach uses lot of resources. if has better solution glad see it.

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...

i'm working on adding multiple querystring , doesn't seem work. i've found codes seems work others might i'm missing something. i want like: http://mydomain.com/board/?getyear=2013&getsometext2=sometext to http://mydomain.com/board/2013/sometext/ i added code below functions.php file. doesn't seem work should though. this works. echoing querystring gets both variable without problem. http://mydomain.com/board/2013/sometext/ but doesn't. tested querystring vis isset() seems nothing being set/get http://mydomain.com/board/2013/ function add_query_vars($vars) { $vars[] = "getyear"; $vars[] = "getsometext2"; return $vars; } add_filter('query_vars', 'add_query_vars'); function add_rewrite_rules($arules) { $anewrules = array('board/([^/]+)/([^/]+)/?$' => 'index.php?pagename=board&getyear=$matches[1]&getsometext2=$matches[2]'); $arules = $a...
