CUDA-native NEXRAD workstation with live Level 2 ingest, national mosaics, 3D volumes, archive playback, warning overlays, and color-table support.
cursdar2 is a CUDA-native NEXRAD workstation focused on fast live Level 2 ingest, responsive 2D/3D radar rendering, archive review, and warning-overlay analysis. It is being built as a standalone successor to cursdar: same GPU-first mentality, much cleaner operator workflow, and a repo that can evolve independently.
This release ships the live-loop overhaul and compare-pane follow-through work.
Highlights:
- Unified bottom live-loop transport bar and scrub timeline
- Progressive loop loading with newest-first backfill and visible progress states
- Quad-pane loop playback now follows loop history instead of only current live data
- Live-loop crash fixes around progressive loading, scrubbing, and view changes
- Local-history loop refreshes on pan/zoom and product changes
Known issue:
- Loop play state does not always carry forward across every tilt/product change yet; that fix is next.

Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
