c++ - Cartesian to quaternion glm -

-

i have vector pointing in direction need rotate, need convert quaternion first. cannot find converting cartesian coordinates quaternions in glm. such function exist?

maybe these out. can found on website in api documents v0.9.6:

glm_func_decl tvec4<t, p> glm::rotate( tquat<t,p> const &q, tvec4<t,p> const &v )     rotates 4 components vector quaternion.     see glm_gtx_quaternion     glm_func_decl tquat<t, p> glm::rotation( tvec3<t,p> const &orig, tvec3<t,p> const &dest )  compute rotation between 2 vectors.     param orig vector, needs normalized param dest vector, needs normalized     see glm_gtx_quaternion

and

template<typename t, precision p>   glm_func_decl tvec3<t,p>  rotate( tquat<t,p> const &q, tvec3<t,p> const &v )   template<typename t, precision p>   glm_func_decl tvec4<t,p>  rotate( tquat<t,p> const &q, tvec4<t,p> const &v )   template<typename t, precision p>   glm_func_decl tquat<t,p>  rotation( tvec3<t,p> const &orig, tvec3<t,p> const &dest )   template<typename t, precision p>   glm_func_decl tquat<t,p>  shortmix( tquat<t, p> const &x, tquat<t, p> const &y, t const &a )   template<typename t, precision p>   glm_func_decl tquat<t,p>  squad( tquat<t,p> const &q1, tquat<t,p> const &q2, tquat<t,p> const &s1, tquat<t,p> const &s2, t const &h )   template<typename t, precision p>   glm_func_decl tmat3x3<t,p>  tomat3( tquat<t,p> const &x )   template<typename t, precision p>   glm_func_decl tmat4x4<t,p>  tomat4( tquat<t,p> const &x )    template<typename t, precision p>   glm_func_decl tquat<t,p>  toquat( tmat3x3<t,p> const &x )   template<typename t, precision p>   glm_func_decl tquat<t,p>  toquat( tmat4x4<t,p> const &x )

within these list of functions; there functions allow rotate using quaternion using 2 vectors returns quaternion, convert , matrix3x3 or 4x4 , other useful functions.

i'm building custom apache module. how retrieve variable apache configuration inside module? see variable "some_var_config_from_apache_or_htaacess" inside apache module: /* source: http://people.apache.org/~humbedooh/mods/examples/mod_example_1.c */ /* include required headers httpd */ #include "httpd.h" #include "http_core.h" #include "http_protocol.h" #include "http_request.h" static void register_hooks(apr_pool_t *pool); static int example_handler(request_rec *r); /* define our module entity , assign function registering hooks */ module ap_module_declare_data example_module = { standard20_module_stuff, null, // per-directory configuration handler null, // merge handler per-directory configurations null, // per-server configuration handler null, // merge handler per-server configurations null, // directives may have httpd register_hoo

when debug code , read line mocklessonplannerafactory creation error: constructor arguments cannot passed interface mocks. var mockschoolclasscodeservice = new mock<ischoolclasscodeservice>(); var mockdateservice = new mock<idateservice>(); var mocklessonplannerafactory = new mock<ilessonplannerafactory>(mockdateservice.object); var mocklessonplannerbfactory = new mock<ilessonplannerbfactory>(mockdateservice.object); var service = new timetableservice(mockunitofwork.object, mocklessonplannerafactory.object, mocklessonplannerbfactory.object, mockschoolclasscodeservice.object); my timetableservice accepts instances of interface type only. mocklessonplannerafactory , bfactory... want in constructor idateservice passed. what wrong code? the clue in error message "constructor arguments cannot passed interface mocks." the mock created interface have default constructor because interfaces don't have constructor. remember mockin
