Vivid is a modern C++ 3D engine using OpenGL4+.
It is written using Visual C++ 2022, and relies on several open source projects to achieve it's goal of making it easy and run to make modern games with it.

Features

• GPU Accelerated Skeletal animations for actors.
• Unified lighting and shadows.
• Post-Processing with both GL Compute, and OpenCL realized acceleration.
• Full Scene Graph system to make it easier to realize your goals.
• Clever 2D renderer, that batches and speeds up rendering of thousands of images per frame.
• SmartMeshes - Using bindless textures to reduce whole scenes to a single draw call.
• Octree scene acceleration.
• Full synced video+audio playback, supporting many formats including MP4+Mov+Mkv+Avi
• Real time environment mapping and refractions.
• AssImp importer, that lets you import over 40+ formats into engine compatible nodes.
• State system, allows you to easily structure advanced applications.
• Easy to use material system, with support for different material types.
• Normal Mapping for per pixel realistic lighting.
• Terrain system with two forms of terrain generation using height-maps.
• Multiple light sources.
• Full physics based on Nvidia Physx 4.1, including all common types including tri-meshes.
• Component system to easily argument the engine's scene with custom game logic.
