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
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…
The post shows a template about how to send file to our remote server. We need to prepare html page, javascript and php script. HTML Page Write a web page and import front.js that contains submit event. front.html: <!DOCTYPE html> <html> <body> <div key=”uploadMeshContent” id=”content”> <input type=”file” id=”uploadMesh” name=”uploadMesh”/> <progress Read more…
Open File By Browser The FileReader object lets web applications asynchronously read the contents of file. You can feel the effect at: https://www.weiy.city/web-test/open-file/ <!doctype html> <html lang=”en”> <head> <title>Test</title> </head> <body> <input type=”file” id=”file-input” /> <h3>Contents of the file:</h3> <pre id=”file-content”></pre> <script> function displayContents(contents) { var element = document.getElementById(‘file-content’); element.textContent Read more…
The math formula can be rendered successfully if the relative code had been written when load HTML page. Example: jsbin.com But it would fail if we change math formula code after loaded page sometimes. So we need to update the target html elements manually. Note: if you can’t access the 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…
We will render math Formula in browser by Js engine MathJax. Download the mathjax package to host it from our own server. git clone https://github.com/mathjax/MathJax.git mj-tmp mv mj-tmp/es5 <path-to-server-location>/mathjax rm -rf mj-tmp Write a JS file which import mathjax to analyze string which contains latex math code. check-for-tex.js: (function () 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…
