viewport-lib

viewport-lib is a gpu-accelerated 3D viewport library for rust. The library gives you a renderer, camera, picking-tools, light sources, gizmos and scene primitives.

Whichever gui library you choose to use (winit, eframe, Iced, Slint, etc.), the integration model stays the same in each case:

• your application owns the window, event loop, and tool state;
• viewport-lib owns rendering and viewport-side maths.

WARNING: viewport-lib has only recently been extracted as a stand-alone library from a separate project and the API is still somewhat unstable.

Core features

• mesh, point cloud, polyline, and volume rendering
• directional lighting, shadow mapping, and post-processing
• material shading, normal maps, transparency, outlines, and x-ray views
• clip planes, section views, scalar coloring, and colormaps
• arcball camera, view presets, framing, and smooth camera animation
• CPU/GPU picking, rectangle selection, transform gizmos, and snapping
• annotations, axes indicators

Examples

The examples/ directory contains working integrations for several GUI frameworks.

• winit-viewport: the most basic setup: raw winit + wgpu with no GUI framework. Start here if you want to understand the minimal integration.
• eframe-viewport: a straightforward example of embedding the viewport inside an egui/eframe application using egui_wgpu callback resources.
• winit-showcase: several more advanced rendering options in 9 showcases

Other examples:

• iced-viewport, slint-viewport, winit-showcase, gtk4-viewport

Run examples with:

cargo run --release --example winit-viewport
