javafxgraphics

JavaFX graphics, often referred to as javafxgraphics, denotes the rendering and scene-graph subsystem of the JavaFX platform. It provides the tools for building rich user interfaces with both 2D and 3D graphics.

The core concept is the scene graph, a hierarchical collection of Nodes such as Group, Region, Shape (Rectangle, Circle, Path), ImageView, and Canvas. Applications lay out and render UI by composing nodes, applying transforms, effects, and CSS-based styles.

Rendering is handled by the Prism pipeline, which leverages hardware acceleration on supported GPUs and falls back to software rendering if necessary. Glass handles windowing and input. The JavaFX graphics stack is implemented in OpenJFX, the open-source reference implementation.

2D rendering covers shapes, images, text, clipping, and effects; 3D adds SubScene, meshes, lighting, and materials. The Canvas API provides immediate mode drawing via a GraphicsContext, while the scene graph handles retained rendering.

The graphics subsystem supports animation, CSS styling, property bindings, and interoperability with other Java UI toolkits. It runs on Windows, macOS, and Linux, and can be embedded in Swing applications through JFXPanel.
