# Viz2D
Viz2D is a 2D visualization library based on OpenCV.
It features OpenGL/OpenCL/VAAPI interoperability.
It should be included in OpenCV-contrib once it is ready.
# Demos
The goal of the demos is to show how to use Viz2D in conjunction with interop options on Linux to create programs that run mostly (the part the matters) on the GPU. Until the [necessary changes](https://github.com/opencv/opencv/pulls/kallaballa) are pulled into the official repository you need to build my fork of OpenCV 4.x.
Viz2D is a 2D visualization library based on OpenCV. It features OpenCL/ OpenGL, OpenCL/VAAPI interoperability and a GUI based on nanogui. It should be included in OpenCV-contrib once it is ready.

There are currently eight demos. The shader-demo, font-demo, optflow-demo and beauty-demo can be compiled to WebAssembly using Emscripten but for now you have to figure out how to do it yourself :).
## Online Demos
Please note that the following online demos are slower and/or have less features than the native versions.

# Requirements
* Support for OpenCL 1.2
* Support for cl_khr_gl_sharing and cl_intel_va_api_media_sharing OpenCL extensions.

## beauty-demo
Face beautification using face landmark detection (OpenCV/OpenCL), nanovg (OpenGL) for drawing masks and multi-band (OpenCV/OpenCL) blending to put it all together. Note: There are sometimes little glitches because face landmark detection is not very accurate and has rather few points.
