MVP Transform Visualizer

"The engines don’t move the ship at all.

The ship stays where it is and the engines move the universe around it."

— Futurama

A raylib demo to visualize the Model, View, and Projection (MVP) matrices.

This project is a C rewrite of @diskhkme's MVP Transform Visualizer with additional features, for the "Computer Graphics" (1214-3005) course at Chungnam National University.

Feel free to try the WebAssembly version here!

Building

Compiling for Windows

w64devkit

Download the latest release of w64devkit from here, extract the .zip file to your working directory, and run w64devkit.exe.

$ wget -O raylib.zip https://github.com/raysan5/raylib/archive/refs/tags/5.5.zip
$ unzip raylib.zip && mv raylib-5.5 raylib
$ make -C raylib/src

$ wget https://github.com/jdeokkim/mvp-demo/archive/refs/heads/main.zip
$ unzip main.zip && mv mvp-demo-main mvp-demo
$ make -C mvp-demo -f Makefile.mingw

Compiling for GNU/Linux

Debian / Ubuntu

$ sudo apt update && sudo apt install libasound2-dev libgl1-mesa-dev \
  libglu1-mesa-dev libx11-dev libxrandr-dev libxi-dev libxcursor-dev \
  libxinerama-dev libxkbcommon-dev
$ git clone https://github.com/raysan5/raylib ~/raylib && cd ~/raylib/src
$ make PLATFORM=PLATFORM_DESKTOP GLFW_LINUX_ENABLE_WAYLAND=OFF && make install

$ git clone https://github.com/jdeokkim/mvp-demo
$ cd mvp-demo && make

Compiling for the Web (LLVM-to-WebAssembly)

Debian / Ubuntu

Compiling for the Web requires installation of the Emscripten SDK.

$ git clone git clone https://github.com/emscripten-core/emsdk && cd emsdk
$ ./emsdk install latest
$ ./emsdk activate latest
$ source ./emsdk_env.sh

Then, you must recompile raylib for the Web:

$ git clone https://github.com/raysan5/raylib && cd raylib/src
$ make -j`nproc` PLATFORM=PLATFORM_WEB GRAPHICS=GRAPHICS_API_OPENGL_ES3 -B

Finally, in order to build this project, do:

$ git clone https://github.com/jdeokkim/mvp-demo
$ cd mvp-demo && make -f Makefile.emcc

Cross-compiling from GNU/Linux to Windows (WSL2)

Debian / Ubuntu

$ sudo apt install mingw-w64
$ git clone https://github.com/raysan5/raylib && cd raylib/src
$ make CC=x86_64-w64-mingw32-gcc AR=x86_64-w64-mingw32-ar OS=Windows_NT

$ git clone https://github.com/jdeokkim/mvp-demo
$ cd mvp-demo && make -f Makefile.mingw
