Here are two videos for showing using the web app on this website to smooth local parts and delete cells of the mesh objects. Web App : https://www.weiy.city/functions/3D-Model-Editor/ youtube – local area edit youtube – local area edit bilibili – local area edit bilibili – local area edit
Here are two videos for showing using the web app on this website to fill the holes on the mesh and generate convex hull for a model. Web App : https://www.weiy.city/functions/3D-Model-Editor/ youtube – fill hole youtube – convex hull bilibili – fill hole bilibili – convex hull
Here are two videos for showing using the web app on this website to decrease the resolution of mesh and clip 3D model by plane. Web App : https://www.weiy.city/functions/3D-Model-Editor/ youtube – decimate data bilibili – decimate data youtube – clip 3D model bilibili – clip 3D model
Add file chooser in html. <input type=”file” id=”file-input” style=”color:white;” /> Choose file and convert the data to uint array, use FS library provided by Emscripten to write it to wasm virtual file system. Note: we have to add FS in EXPORTED_RUNTIME_METHODS in CMakeLists.txt for CPlusPlus project. javascript code: function readSingleFile(e) Read more…
The post shows a simple way how to download the 3D Model from web page which constructed by wasm. I assume that you have a 3D model in the scene. Now you want download the mesh from the web page to local disk. Write a CPlusPlus interface to convert mesh Read more…
I will show a way to export CPlusPlus algorithm to javascript code. Write Pollard’s rho algorithm in class Resolver for integer factorization. resolver.h #include <string> typedef long long LL; class Resolver { public: Resolver(); ~Resolver(); std::string GetResolvedResult(int x); protected: void find(LL n,LL c); bool Miller_rabin(LL p); LL Pollard_rho(LL n,LL c); Read more…
Create a file GetPrimers.c which has a simple math function. #include <stdio.h> // export the function. #ifdef __EMSCRIPTEN__ #include <emscripten.h> EMSCRIPTEN_KEEPALIVE #endif int compute( int a, int b ) { int ans = 1; for( int i = 0; i < b; ++i ) { ans = ans * a; Read more…
Somtimes the user’s browser is not the newest version. It may not support WebAssembly or a few functions. So we have to test it before using. Is WebAssembly Supported? Import a WebAssembly module and create an instance of it. Track this process to see if any problems arise. <!doctype html> Read more…
Create a small program by computer language C, it print primers in range (1, 6000). Let’s compile it by emcc and generate a template html file. #include <stdio.h> const int N = 6000; int primer[N],count; char visit[N] = { 0 }; void GetPrimers() { count = 0; for (int i Read more…
