Changelog

This file records user-visible VisPy2 changes. The project is not yet published; the version below describes the current experimental candidate rather than a package-index release.

Unreleased

Protocol architecture

  • Emit identity-only GSP panels plus explicit full-target panel layout intent.
  • Move clipping policy to visual attachments through Axes.set_clip_scope.
  • Expose typed local EmissionFeature values for textured-unlit mesh and linear-filter emission; these values are non-wire producer information and never session capabilities.

Documentation

  • Reconciled historical qualification reports with subsequent owner acceptance.
  • Expanded the user guide to cover the complete public 2D surface, scalar images, color scales, colorbars, guides, lighting, output, sessions, and limitations.
  • Added a compact public API reference plus installation and development guidance.

0.2.0a1 — unpublished candidate

Added

  • Backend-neutral Figure, Axes, and Axes3D producers for typed GSP scene snapshots.
  • Points, markers, pixels, segments, paths, vectors, bounded primitives, text, meshes, and images.
  • Scalar color scales, scalar point/marker encoding, image mapping, and colorbar guide intent.
  • Semantic axes labels, titles, explicit ticks, grids, ranges, and canvas size.
  • Perspective and orthographic View3D cameras with fit, orbit, pan, zoom, and reset reducers.
  • DATA-space spheres, vectors, primitives, pixels, and screen-facing text billboards in View3D.
  • Bounded mesh textures and flat-Lambert lighting with ambient and directional light state.
  • Explicit caller-owned GSP sessions, resolved-layout forwarding, and bounded query forwarding.
  • Matplotlib one-shot savefig and blocking show conveniences.
  • Cross-backend galleries, live paired review, exact-wheel validation, and portable evidence.

Boundaries

  • Scene execution currently accepts exactly one 2D or 3D axes.
  • VisPy2 imports gsp-core but no concrete adapter.
  • Non-blocking and interactive execution requires an explicit caller-owned session.
  • Datoviz DATA-space scalar images and linked colorbars are supported on the qualified retained View2D path; image-texel readback and comprehensive 3D/item/glyph queries remain unsupported.
  • Live Datoviz View3D navigation remains experimental and opt-in.
