What is

Simple graphics engine created for educational purpose.

Features:

• aim on code readability and extensibility
• cross-platform (tested on Windows, Ubuntu and MacOS)
• abstraction layer for different graphical APIs:
  • OpenGL 4.5 renderer
  • Metal renderer powered by Apple Metal-cpp library (WIP, by state of 19.01.2022 could render only one example)
• two IO abstraction backends:
  • GLFW
  • SDL
• resource (textures, models, shaders) loading
• semiautomatical state managing
• c++20

Examples:

• examples - contains just one example with rotating cube, but thinking as set of examples/tests
• sandbox is a playground for testing engine features
  • deferred renderer over simple scene graph
  • simple procedurally generated terrain with tesselaton
• test_task is a program that demonstates some UI and plot rendering (pretty obsolete)

Dependencies:

Needs last version of C++20 compiler (may build under Visual Studio 16.10, XCode 13 and Clang 13)
Also check if you have Conan package manager - almost* all should be installed automatically.

The only exception is MacOS-specific Metal-cpp which has no official repository and requires small patch from here [will be automated soon]

Uses libraries:

• GLFW / SDL
• glm
• stb
• assimp [optional]
• gtest [optional]
• glad
• nlohmann-json
• fx-gltf
• Metal-cpp [optional, Mac only]
