SimpleRenderEngine
The goal of SimpleRenderEngine (sre) is to provide easy way to get started with graphics programming in 2D or 3D without a deep knowledge about the low-level graphics APIs like OpenGL, DirectX and Vulkan.
SimpleRenderEngine currently depends on Simple Direct Layer 2.x (SDL2), SDL2-image, OpenGL Mathematics (GLM), and OpenGL 3.3 (or higher), Dear ImGui and runs on both Windows, macOS and Linux.
sre provides:
- Virtual camera (perspective and orthographic)
- Texture support (JPEG, PNG)
- Cube map support
- Mesh support (with custom vertex attributes)
- Shaders (PBR, Blinn-Phong, unlit, alpha blending, and custom shaders)
- Enforces efficient use of OpenGL
- Forward rendering
- Full C++14 support
- Support for 2D or 3D rendering
- GUI rendering (using Dear ImGui)
- Emscripten support (allows cross compiling to HTML 5 + WebGL)
- VR support (OpenVR)
- Bump mapping
- Shadowmap
To keep sre as simple and flexible as possible the following features are not a part of sre:
- Scenegraphs
- Deferred rendering
- Dynamic particle systems
Getting started
First clone the library (git clone --recurse-submodules https://github.com/mortennobel/SimpleRenderEngine.git). You can use of the examples as starting point.
If you want to create new projects using SimpleRenderEngine you can use SimpleRenderEngineTemplate as a simple project template.
Also look into SimpleRenderEngineProject as starting point, which bundles all/most dependencies for Windows and macOS.
Examples
Example usage can be found in the examples folder.
Documentation
API documentation is defined in header files.
