suppose, near , far values of gluperspective 1 , 100 respectively. want clip portion of triangle having z values greater (-near) or less (-far) , divide remaining polygon 2 triangles following images. considering far plane: considering near plane: another case: i have calculated intersection points in following way: z_clip=-far (for considering far plane) or z_clip=-near (for considering near plane) for example: f consider edge between (x1,y1,z1) , (x2,y2,z2), then: co-efficient = (z_clip - z1) / (z2 - z1) xc = x1 + co-efficient * (x2 - x1) yc = y1 + co-efficient * (y2 - y1) zc = z_clip (xc,yc,zc) point of intersection. similarly, can calculate point of intersection other edge. example: edge between (10, 0, -50) , (0, 0, -150) cut in point (5, 0, -100). original triangle: 0 0 -150 10 0 -50 0 10 -50 after clipping: triangle1: 0 10 -50 5 0 100 0 5 -100 triangle2: 10 0 -50 0 5 -100 0 10 -50 am right in calculation procedure or there wrong in procedure?

i developing c++ project in prj_cpp.h starts as // prj_cpp.h #include "lib_cpp.h" extern "c" { #include "lib_c.h" } where lib_cpp.h , lib_c.h header files of external c++ , c libraries respectively. external c++ library lib_cpp.h uses lib_c in following way. // lib_cpp.h namespace some_weird_namespace { extern "c" { #include "lib_c.h" } } because lib_c.h prevents double inclusion, turns out objects in lib_c.h reside in some_weird_namespace has nothing project prj_cpp . on other hand if header file looks like // prj_cpp.h extern "c" { #include "lib_c.h" } #include "lib_cpp.h" i break external c++ project because there nothing under some_weird_namespace because include lib_c.h first. i not allowed modify neither lib_cpp.h nor lib_c.h is there can in prj_cpp.h resolve such issue? i not using some_weird_namespace in project because namespace has nothing it. moreover, num

i trying see hex representation of floating point numbers , compiled code gcc-4.9.2: #include <stdio.h> int main() { double = 100; printf("%f %x\n", i, (double)i); return 0; } i surprised find everytime ran code hex value printed out changed. going on? how can safely print hex representation of floating point number? the %x format specifier requires argument of type unsigned int . you're giving argument of type double . behavior undefined, means far c standard concerned anything can happen -- including changing output other specifiers in same format string. to print hex representation of floating-point number, copy array of unsigned char , print elements of array.

i underline issue in cordova-plugin-mfp-jsonstore during investigation notice in method sendresourcerequest on pushinstance data not sent resourcerequest = new wlresourcerequest('adapters/' + invocationdata.adapter + '/' + invocationdata.procedure, wlresourcerequest.post); resourcerequest.send().then(ipopts.onsuccess, ipopts.onfailure); according me should become: resourcerequest = new wlresourcerequest('adapters/' + invocationdata.adapter + '/' + invocationdata.procedure, wlresourcerequest.post); resourcerequest.sendformparameters({ "params":"['" + json.stringify(collectiondocument) + "']" }); i need use in important project, possible fix possible? regards. daniele if require changes/fixes in jsonstore plug-in ibm need open pmr ibm correct , provide ifix.

i using plotly create stacked bar chart below df <- data.frame( var1 = c("ny", "ny", "ny", "sfo", "sfo", "sfo"), var2 = c("low", "medium", "high", "low", "medium", "high"), value = c(10,15,20,10,20,25) ) df$var2 <- factor(df$var2, levels = c("low","medium","high")) # sort factor table df <- arrange(df, var2) col <- list( color = ifelse( df$var2 == "low", "steelblue", ifelse( df$var2 == "medium", "darkorange", "olivedrab" ) )) # plot plot_ly( df, x = ~ var1, y = ~ value, color = ~ var2, marker = col, type = "bar" ) %>% layout(barmode = "stack") there 2 issues facing: first legend not coming correctly (see image) . second since have dynamic table, there possibility there 1 value in var1 ,

in spark application, have aws credentials passed in via command line arguments. spark.sparkcontext.hadoopconfiguration.set("fs.s3.awsaccesskeyid", awsaccesskeyid) spark.sparkcontext.hadoopconfiguration.set("fs.s3.awssecretaccesskey", awssecretaccesskey) spark.sparkcontext.hadoopconfiguration.set("fs.s3.impl", "org.apache.hadoop.fs.s3native.natives3filesystem") however, in cluster mode explicitly passing credential between nodes huge security issue since these credentials being passed text. how make application work iamrole or other proper approach doesn't need 2 lines of code in spark app: spark.sparkcontext.hadoopconfiguration.set("fs.s3.awsaccesskeyid", awsaccesskeyid) spark.sparkcontext.hadoopconfiguration.set("fs.s3.awssecretaccesskey", awssecretaccesskey) you can add following config in core-site.xml of hadoop conf , cannot add in code base <?xml version="1.0"?> <?xml-stylesh

i want reuse series of regular expression replacements regularly. in plain emacs, record keyboard macro, entering more useful regular expressions provided spacemacs, recording stops automatically after first replacement step. how can this, , more general macro recording? also, 2 recording mechanisms (the emacs , vim one) implemented same under hood, or coexist? thanks

i'm writing trying learn flex / bison. i've got basic c examples now, i'd move on doing c++ ast tree. c++ makes type of object oriented program easier c. however, there seems issue c++ generation flex , i'm unsure how resolve it. want add methods warning/error reporting going inherit yyflexlexer , in '.l' file call stuff warning(const char* str) , error(const char* str) appropriate. however, 'yyflexlexer redefinition' error among others when try perform inheritance in way believe documentation says this. lexer.l %option nounistd %option noyywrap %option c++ %option yyclass="nlexer" %{ #include "nlexer.h" #include <iostream> using namespace std; %} %% [ \t]+ \n { return '\n';} [0-9]+(\.[0-9]+)? { cout << "double: " << atof(yytext()) << endl;} . {return yytext()[0];} %% int main(int , char**) { nlexer lexer; while(lexer.yylex() != 0) { }; return 0; } nlexer.h #ifn
