VERA is powerful C++14 and OpenGL/WebGL framework designed for creating and displaying real-time visual application in a big variety of surfaces and devices.
VERA brings low level support for moder CG techniques such us:
- GLSL Shaders affordances for: hot-reloading, libraries (ex: LYGIA) and define flag injection
- Geometry generation and manipulation (2D/3D)
- Camera controls (orbit, first-person, etc)
- Transform stack (push/pop)
- Basic 2D/3D drawing API (points, lines, shapes, meshes, etc)
- Textures loading and manipulation
- Offscreen Framebuffers
- Double buffering (ping-pong)
- Post-processing effects
- Pyramid algorithms (ex: poisson fill)
- Flood algorithms (ex: jump flood for sdf generation)
- FXAA Anti-aliasing
- 3D Models loading and rendering, including: PLY, OBJ, GLTF/GLB and STL formats.
- GSPLAT loading and rendering
- PBR Materials
- HDRI Environments and Lighting
- Dynamic Atmospheric Lighting
- Shadow Mapping
- TTF Font loading and rendering
- Audio input analysis (FFT, Amplitude)
- Video input/output (ffmpeg based)
- Histogram Equalization
- Centralize asset management (shaders, textures, models, fonts, lights, etc)
VERA applications can be compiled as:
- native OpenGL/ES app on Linux, Windows and MacOS (with support for ARM and x86 architectures)
- console OpenGL/ES app for embebed systems (such us Raspberry Pi, Nvidia Jetson Nano, Khadas VIM4, etc) with out window manager
- browser WASM/WebGL2 app
VERA brings support for more novel displays and surfaces such us:
VERA is the merge between, ADA (a minimal library to create OpenGL ES & WebGL apps) and HILMA (a 2D/3D geometry library).
VERA have an App class and a drawing API similar to P5js's API that could be use for more novel artist that are searching to improve the performance of their art works or displaying them in a bigger set of formats, devices or displays. This doesn't mean P5js code, addons and plugins will work out of the box in VERA, but mostly that app.h and ops/draw.h will provide functionality familiar and (when possible) width identical behavior. At the end of the day C++ is a different programing language with specific and unique sintax. Hopefully VERA can also serve for generative or novel artist already familiar to Processing and P5js that desire to adventure into C++. It can be provide a nice transition to OpenFrameworks and Cinder.
Ultimatelly VERA is designed to let artist code their works once and display them in a biffer range of surfaces. From native apps to custom displays powered by embebed systems such us Raspberry Pi; or from holographic screen like those from Looking Glass Factory, sandboxed web app (like generative NFT projects ) to AR/VR experiences through WebXR protocol.
By sponsoring VERA development or contribute by helping to:
- fix bugs
- improve the documentation
- create more examples
- bring support for more devices and type of displays (specifically embebed systems such us Raspberry Pi, Nvidia Jetson Nano, Khadas VIM4, etc)
- expand the drawing API (
ops/draw.h) to better match P5js API - migrate the underlying graphic API to WebGPU
