graphics - Drawing millions of segments on screen -

-

i draw millions of line segments screen. of time user see area of "universe", user should have ability "zoom" out see line segments @ once.

my understanding primitive "triangle", have express line segments triangles. millions of triangles.

is xna right tool job, or slow?

additional detail:

  1. this not game, modeling program of processes.
  2. i not care language use (xna recommended me)

p.s.: please let me know if need additional detail.

my understanding primitive "triangle", have express line segments triangles. millions of triangles.

incorrect, xna can draw lines in following manner:

graphicsdevice.drawindexedprimitives(primitivetype.linelist, vertexoffset, 0, numvertices, startindex, primitivecount);

(or primitivetype.linestrip if end vertex of line1 start vertex of line2).

is xna right tool job, or slow?

xna "a tool", , if you're drawing lot of lines definately going faster gdi+ , easy implement c++ in combo unmannaged d3d. drawing line cheap operation. advice install xna , quick prototype see how many lines can draw @ same time. (my guess @ least 1 million). see if need use advanced techniques described other posters.

also "polyline simplification" technique suggested felice pollano doesn't work individual lines, models made of triangles (you can exchange lot of small triangles few bigger once increase performance decrease visuals, if you're zoomed out pritty far nobody notice) won't work "thickened lines" because consist of 2 triangles. (unless if allow bended lines).

java - SNMP4J General Variable Binding Error -

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

Determine if a XmlNode is empty or null in C#? -

-
the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
