VisPy is a scientific visualisation library designed to make effective use of graphics hardware when displaying large or rapidly changing datasets. It supports interactive two-dimensional and three-dimensional graphics through OpenGL.
The library is suitable for applications requiring responsive visual interaction with complex scientific information. Examples include large point clouds, volumetric measurements, image data, geometric models and continuously updating numerical displays.
VisPy provides several abstraction levels. Developers can work directly with graphics resources through its gloo interface, construct reusable visual objects or assemble complete interactive scenes. This flexibility allows applications to balance performance, control and development complexity.
This is free and open source software.
Key Features
- Hardware-accelerated rendering using OpenGL.
- Interactive 2D and 3D visualisations for scientific datasets.
- Display large collections of points, lines and other graphical primitives.
- Render triangle meshes, surfaces and volumetric data.
- Scenegraph system for combining visual objects within interactive views.
- Visual objects provide reusable components for images, markers, meshes and other data representations.
- Gloo interface provides object-oriented access to OpenGL resources.
- Custom shader support for specialised rendering techniques.
- Coordinate transformations for positioning and manipulating graphical objects.
- Interactive cameras for navigating two-dimensional and three-dimensional scenes.
- Colour maps and visual styling facilities for scientific displays.
- Support for frequently updated visualisations and real-time data.
- Integration with supported graphical interface toolkits.
- Event handling for mouse, keyboard and canvas interactions.
- High-level plotting and scene interfaces for applications that do not need direct OpenGL control.
- Facilities for embedding accelerated visualisations within scientific interfaces.
