Simple viewer with SDL2

This viewer uses NanoRT(SW ray tracer) to render the model and display it using SDL2 (So no OpenGL dependency)

Status

W.I.P.

Requirements

  • C++14 compiler
    • external library imgui_sdl requires C++14
  • cmake
  • X11 related package(Linux only)
  • SDL2

Setup

You may use system installed SDL2, but we recommend to build SDL2 from source codes. Please download SDL2 source package and unpack it to ../common/ See ../common/README.sdl2 for details.

Build

$ mkdir build
$ cd build
$ cmake ..
$ make

Run

$ ./usdz_view <input.usdz>

WebAssembly demo

Setup emcc, then

$ ./bootstrap-emscripten-linux.sh
$ cd build_emcc/
$ make

Then run http server(e.g. python -m http.server) and open usdz_view.html.
