  1. Thanks! That's really helpful
  2. I am making some fractal which is needed Complex Numbers. I use Python Module's Complex Method. => complex(1, 2) = 1+2j But I want to know using Complex Numbers via VEX Language. According to SideFX's Houdini Documents, vector2 : Two floating point values. You might use this to represent texture coordinates (though usually Houdini uses vectors) or complex numbers. But I cannot know how to express the complex numbers in VEX.
  3. I really appreciate of your answer, Illusionist. Thanks! I will try right now.
  4. Are there any reference of OpenGL Context for houdini? like vex context(P, Cd, ....)
  5. Hi, there. I have some HDAs that use an external python module. I'd like to package the module into the HDAs so that external files are not necessary to use them. Currently I am embedding the python module using the “Custom Script” event handler, and I want to read file from “Extra Files” Tab. I want to write & read files from HDA's Extra Files Tab. Because I don't want to write & read files from External Directory. If I changed computer, I should move not only HDA asset but related External Files. I want to embed all files related to HDA. The Extra File is just txt file or json file. I already ask same question to sidefx forum. But, I receive some useful tips. I try HDADefinition Module but I cannot find to write in HDA. I spend about two weeks.. otl OTL Is there any way to write in the HDA's Extra Files? Link I asked same question
  6. Thank you ! Thanks you! Nowadays, I study in compatible environment and I successfully implement Dijsktra Function on my own VEX function!
  7. I am a beginner who studied HDK. I use VC14(visual studio 15), Houdini 15.5. I study many examples in SOP folder and etc... There are two questions. First, GA_PointGroup * mygroup; GEO_Point * ppt; GR_FOR_ALL_GPOINTS_NC(gdp, GEO_Point, pt) { mygroup->add(ppt->getNum()); } This Code should be fixed by reference HDK Documents(Geometry Porting Cookbook) http://www.sidefx.com/docs/hdk/_h_d_k__g_a__porting.html#HDK_GA_PortingCookbook_Simple_Name_Translation /* *Adding To A Group * *GB Code *group->add(prim->getNum()) *==> *GA Code *group->add(*prim); *group->addIndex(prim->getNum()); */ GA_PointGroup * mygroup; GEO_Point * ppt; GR_FOR_ALL_GPOINTS_NC(gdp, GEO_Point, pt) { mygroup->add(*ppt); mygroup->addInex(ppt->getNum()); } I changed like this. But mygroup->add(*ppt); still error... Is There any way? Second, I have one more question about GEO_PointList For the Documents, GB_ElementList GB had arrays of pointers to objects. As these objects no longer exist, code using element arrays should likely be re-written to be more efficient. The GA version of element lists return by value (not by reference). // GB Code GEO_PointList &pnts = gdp->points(); ==> // GA Code GEO_PointList pnts = gdp->points(); But there is no GEO_PointList.. I check it existed 13.0 not 15.0 I traverse 13.0 HDK Documents related GEO_PointList.. It's so difficult to find out the replacements. I search for Major Changes and HDK Forums, Documents. I cannot find. I want use points() function.. OTL
  8. Okay That works perfectly. Thank you!
  9. Thank for answering kindly. Yes, I change output directory like this. In Visual Studio 2015, Property Pages - Linker - General - Output File : C:\Program Files\Side Effects Software\Houdini 15.5.480\houdini\vex\myprint.dll But, Windows 10 needs Administor authorization to access or modify in C drive especially, Program Files. So, I solve this program by window mount using mklink.
  10. VEX_example.C cannot print Vectors. So, I modified function. it works! it's fun. Thank you for answering again. Could I ask one more question? This is VEXdso file in $HFS/houdini/vex. #ifndef __HFS_VEXdso__ #define __HFS_VEXdso__ // // VEXdso // // This file contains the definitions for VEX plug-in functions. // // There is currently one dynamic loaded VEX instructions. // // Please see $HH/vex/dso/VEX_VexOp.html for more details. // // // Since Windows dynamic objects have a different file extension than // most unix platforms, we define a macro which makes the correct // filename. We also simplify the path construction a little. // #if defined(WIN32) #define DSO_FILE(filename) filename.dll #elif defined(MBSD) #define DSO_FILE(filename) filename.dylib #else #define DSO_FILE(filename) filename.so #endif // Define VEX plug-ins here DSO_FILE(vex/VEX_OpRender) DSO_FILE(FLU_Filament) DSO_FILE(vex/myprint) // This Line is I added. // Make sure to undefine the macro before doing any further includes #undef DSO_FILE // // When copying this file to other locations in the HOUDINI_PATH, // please uncomment the following line (or change it) so that any // other VEXdso files get processed. Also, you'll have to change the // #ifndef/#define at the top of this file. // // #include "$HFS/houdini/vex/VEXdso" #endif I add the line : DSO_FILE(vex/myprint) myfunc.dll is in $HFS/houdini/dso/vex. But, In my Setting : When I compile VEX_example.C using Visual Studio 2015, The myfunc.dll file is generated in $HOME/houdini15.5/dso So I have to move again again whenever I recompile. How Could I modify VEXdso when houdini starts up scanning $HOME/houdini15.5/dso. I try to modify like DSO_FILE($HOME/houdini15.5/dso/myprint) or DSO_FILE(/c/Documents/.../.../houdini15.5/dso/myprint), it doesn't work. This is vector print out example.
  11. I successfully compiled VEX_example.C (code is at below the link) http://www.sidefx.com/docs/hdk15.5/_v_e_x___example_8_c.html I understand this produces Build-In VEX function like lerp(), geoself(), addpoint().... How could I use produced function in VEX? I refer to see http://www.sidefx.com/docs/hdk15.5/_v_e_x___example_8vfl_source.html. Make VEX operator and try to use function, but I can't.. Is there any example?
  12. Thank you for answering. I use Cop and finally I use instance I solve! Thank you!
  13. Thank you. But it's the using pre-maked map.pic. I mean the object applied shop's shader(.vfl code) and extract the Color Value From that.
