mesh - Reconstruct surface from 3D triangular meshes -

-

i have 3d model, consists of 3d triangular meshes. want partition meshes different groups. each group represents surface, such planar face, cylindrical surface. surface recognition/reconstruction.

the input set of 3d triangular meshes. output mesh segmentations per surface.

is there library meets requirement?

if want go lots of mesh processing, point cloud library idea, i'd suggest cgal: http://www.cgal.org more algorithms , loads of structures aimed @ meshes.

lastly, problem describe solved on own:

  1. enumerate vertices
  2. enumerate polygons
  3. create array of ints size of number of vertices in "big" mesh, initialize 0.
  4. create array of ints size of number of polygons in "big" mesh, initialize 0.
  5. initialize counter 0
  6. for each polygon in mesh, @ vertices , value each has in array. if values each vertex zero, increase counter , assign each of values in vertex array , polygon array correspondingly. if not, relabel vertices , polygons higher number smallest, non-zero number.

the relabeling can done table. might save lots of issues interfacing code library you're not interested in.

django - How can I change user group without delete record -

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

java - Need to add SOAP security token -

-
i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
