Requirements

• Execute on the web browser platform using WebGL.
• Execute on the Microsoft Windows platform using DirectX.
• Use the C++ programming language.
• Use existing open source libraries when possible.
• Identify a library for 3D graphics rendering.
• Identify a library for audio output and sound mixing.
• Identify a library for input processing of mouse, keyboard, and touch.
• Identify a library for matrix math associated with 3D graphics.
• Identify a library for the main application window.
• Identify a library for user interface controls.

Result - Sokol is Great!

https://github.com/floooh/sokol

https://github.com/floooh/sokol-samples

• Using Sokol for 3D graphics rendering (sokol_gfx.h).
• Using Sokol for audio output (sokol_audio.h).
• Using Sokol for input processing of mouse, keyboard, and touch (sokol_app.h).
• Using Sokol for the main application window (sokol_app.h).

Result - Dear ImGui is Great!

https://github.com/ocornut/imgui

• Using Dear ImGui for user interface controls.

Result - OpenGL Mathematics (GLM) is Great!

https://github.com/g-truc/glm

• Using GLM for matrix math associated with 3D graphics.

Result - Write Some Code

• Using our own source code for sound mixing.

Notes on Sokol Build FIPS

• FIPS is a custom build system for Sokol library.
• FIPS build uses the Python script language. https://www.python.org
• FIPS build uses the git version control. https://git-scm.com
• FIPS build uses the CMake build tool. https://cmake.org

On Windows - Windows Build Debug DirectX 11 (Microsoft Visual Studio)

• Make a directory "build_debug".
• Copy the CogDemoImgui source code into the directory "build_debug".
• Start a Windows PowerShell shell.
• Change directory to "build_debug/CogDemoImgui" (in shell).
• Execute "./fips set config sapp-d3d11-win64-vstudio-debug" (in shell).
• Execute "./fips build" (in shell).
• Result is "build_debug\fips-deploy\CogDemoImgui\sapp-d3d11-win64-vstudio-debug\CogDemoImgui.exe".

On Windows - Windows Build Release DirectX 11 (Microsoft Visual Studio)

• Make a directory "build_release".
• Copy the CogDemoImgui source code into the directory "build_release".
• Start a Windows PowerShell shell.
• Change directory to "build_release/CogDemoImgui" (in shell).
• Execute "./fips set config sapp-d3d11-win64-vstudio-release" (in shell).
• Execute "./fips build" (in shell).
• Result is "build_release\fips-deploy\CogDemoImgui\sapp-d3d11-win64-vstudio-release\CogDemoImgui.exe".

On Windows Subsystem for Linux Ubuntu - Web Browser Build (Emscripten)

update packages

• Start a Windows Subsystem for Linux Ubuntu shell.
• sudo apt update
• sudo apt upgrade
• sudo apt install git
• sudo apt install make
• sudo apt install cmake
• sudo apt install ninja-build
• sudo apt install python3
• sudo apt install python-is-python3

redo drive mount for git chmod problem

• sudo umount /mnt/f
• sudo mount -t drvfs F: /mnt/f -o metadata

build .html .wasm .js

• Make a directory "build_wasm".
• Copy the CogDemoImgui source code into the directory "build_wasm".
• Change directory to "build_wasm/CogDemoImgui" (in shell).
• Execute "./fips setup emscripten" (in shell).
• Execute "./fips set config sapp-webgl2-emsc-ninja-release" (in shell).
• Execute "./fips build" (in shell).
• Result is "build_wasm\fips-deploy\CogDemoImgui\sapp-webgl2-emsc-ninja-release\CogDemoImgui.html".
• Result is "build_wasm\fips-deploy\CogDemoImgui\sapp-webgl2-emsc-ninja-release\CogDemoImgui.wasm".
• Result is "build_wasm\fips-deploy\CogDemoImgui\sapp-webgl2-emsc-ninja-release\CogDemoImgui.js".
• Deploy to a web server.
