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.
