PhysX WASM for Webaverse client

Introduction

Webaverse uses a WebAssembly Build of PhysX, a C++ open-source realtime physics engine middleware SDK developed by Nvidia. It is compiled with EMSDK.

Setup Requirements

Get Webaverse PhysX Build (APP-WASM)

• Fork and clone it to your prefered directory.

Get Emscripten SDK

• Clone it and then run these commands inside the emsdk directory: ./emsdk install latest ./emsdk activate latest

Compilation

• Within app-wasm point to the emsdk directory using this command: source /home/user/emsdk/emsdk_env.sh change it to your own path.

• Now inside app-wasm run this to compile: ./compile.sh

• Congrats! If it compiled without errors the finished build should be in app-wasm/bin

Use it in Webaverse

• Copy the geometry.js and geometry.wasm files from app-wasm/bin
• Paste them into app/public/bin in the Webaverse app
• Done! Now reload the Webaverse app and try out your own PhysX configuration!
