The article shows how to create a simple vtk render window project and show it in the web browser. We need emscripten tool and the visualization toolkit installed. emscripten : https://emscripten.org/docs/getting_started/downloads.html VTK: https://vtk.org/ Build the VTK source to get JS library before our coding. This example uses C plus plus Read more…
Here are two videos for showing using the web app on this website to show imported points and do linear transform for the mesh object. Web App : https://www.weiy.city/functions/3D-Model-Editor/ youtube youtube bilibili bilibili

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…
