-Aardvark.Rendering is part of the open-source [Aardvark platform](https://github.com/aardvark-platform/aardvark.docs/wiki) for visual computing, real-time graphics and visualization. This repository heavily builds on datastructures and tools from [aardvark.base](https://github.com/aardvark-platform/aardvark.base). The engine can be used standalone or using [aardvark.media](https://github.com/aardvark-platform/aardvark.media) which provides purely functional ELM style application abstraction.
+The Aardvark.Rendering engine is a high-performance engine that tries to bridge the gap between efficiency and high-level easy-to-use abstractions. The engine is used in applied research and industry as well as basic research, and heavily embraces incremental computation. It tracks all changes in the scene description and automatically updates affected parts in the incrementally maintained optimization data structures. The engine currently has two backends: OpenGL and Vulkan, runs on netstandard, and is basically platform independent. It was born in 2006 and was mostly written in C#, but later moved towards functional programming. Now, most of the code is written in F#. Supported platforms are windows, linux, macOS. Render backends exist for OpenGL and Vulkan.

-The aardvark rendering engine was the vital spark which finally led to the complete ecosystem of libraries, we now call aardvark-platform. The engine as such was born in 2006. At that time, the engine was written mostly in C# (which was rather unusual in a world of highly optimized C++ engines). Later we more and more moved  towards functional programming. In various rewrites we modernized the engine over and over again. Now most code is written in F#. The unique features of the engine are:
- - The engine tries to bridge the gap between *efficiency* and *high-level easy to use abstractions*. We used a lot of energy to get out good performance for a lot cases. We did a lot but we look forward to getting better and better in this regard. [This video](https://www.youtube.com/watch?v=QjVRJworUOw) demonstrates the rapid prototyping features of aardvark.
- - It is used in applied research and industry but it is also used as vehicle for basic research.
- - The engine heavily embraces *incremental computation*. Rendering engines typically use some form of scene description which is then interpreted by the rendering kernel. The interpretation of large scenes quickly becomes a [bottleneck](https://www.cg.tuwien.ac.at/courses/RendEng/2015/RendEng-2015-11-16-paper2.pdf). Aardvark by contrast tracks all changes in the scene description and automatically updates affected parts in the *incrementally maintained optimization datstructures*. The approach was published in a paper [An Incremental Rendering VM](https://www.vrvis.at/publications/pdfs/PB-VRVis-2015-015.pdf). The scene graph concept and implementation is published in the paper [Attribute Grammars for Incremental Scene Graph Rendering](https://www.vrvis.at/publications/pdfs/PB-VRVis-2019-004.pdf).
- - The engine currently has two backends: OpenGL and Vulkan, runs on netstandard and is basically platform independent
- - Not like classic rendering engines, the aardvark rendering engine does not provide any tooling such as level editors etc. but lives from the aardvark platform as whole which provides tools to *create customized tooling for various needs*. 
- - Aardvark does not understand light, shadows or particular material workflows as in most game engines. Instead, the codebase provides a *rich set of tools* to customize those features to fit the needs.
- - For application and UI programming we recommend to climb the abstraction ladder up towards [aardvark.media](https://github.com/aardvark-platform/aardvark.media) which provides easy-to-use ELM style API to both UI and high-performance computer graphics.

+Aardvark.Rendering is part of the open-source [Aardvark Platform](https://github.com/aardvark-platform) for visual computing, real-time graphics, and visualization. Aardvark.Rendering is a stand-alone rendering engine that builds on basic data structures and tools from [Aardvark.Base](https://github.com/aardvark-platform/aardvark.base). It is also integrated into [Aardvark.Media](https://github.com/aardvark-platform/aardvark.media), which provides web-based user interfaces and ELM-style application development. [Aardvark.Algodat](https://github.com/aardvark-platform/aardvark.algodat) provides advanced geometry tooling and algorithms, including out-of-core point cloud rendering and PolyMesh processing algorithms.
