0.6.1

Minor bug fix release to address some lingering issues from 0.6.0, primarily in transfer function rendering and standalone scene export.

Changes

Bug Fixes

• Fix tf conversion for high dynamic ranges, fix blank fragments in max intensity projections of regions with all-zero values (https://github.com/yt-project/yt_idv/issues/302) by @matthewturk in https://github.com/yt-project/yt_idv/pull/304

• Address transfer function issues by @matthewturk in https://github.com/yt-project/yt_idv/pull/303

New Features

• Add units to standalone scene export by @matthewturk in https://github.com/yt-project/yt_idv/pull/306

Project Maintenance

• bump to next dev version by @chrishavlin in https://github.com/yt-project/yt_idv/pull/301

• add unyt as an explicit dependency by @chrishavlin in https://github.com/yt-project/yt_idv/pull/307

Full Changelog: https://github.com/yt-project/yt_idv/compare/v0.6.0…v0.6.1

0.6.0

Highlights

• Releases now ship pre-built wheels for linux (x86_64, aarch64) and macOS (x86_64, arm64) on python 3.10-3.14, attached to the GitHub release and uploaded to PyPI alongside the sdist (https://github.com/yt-project/yt_idv/pull/200).

• imgui is now an optional dependency: install it with pip install yt_idv[gui] for the interactive GUI. A plain pip install yt_idv supports headless rendering only, which allows using yt_idv with python 3.13+ (see https://github.com/yt-project/yt_idv/issues/256, https://github.com/yt-project/yt_idv/pull/268).

• Volume rendering now supports geographic and internal_geographic coordinate systems, and spherical rendering uses full volume element intersections (https://github.com/yt-project/yt_idv/pull/278, https://github.com/yt-project/yt_idv/pull/239).

• The camera gained an orthographic projection option, scenes can be serialized, and data values can be extracted from rendered block scenes (https://github.com/yt-project/yt_idv/pull/265, https://github.com/yt-project/yt_idv/pull/283, https://github.com/yt-project/yt_idv/pull/251).

• Headless rendering is now tested in CI on osmesa, egl and pyglet across linux and macOS, and tests can be run against any of these backends locally (https://github.com/yt-project/yt_idv/pull/257, https://github.com/yt-project/yt_idv/pull/258, https://github.com/yt-project/yt_idv/pull/259, https://github.com/yt-project/yt_idv/pull/260).

• Rendering can now be composited into larger external scenes: an external depth buffer can be supplied to truncate rays at a fixed depth, the EGL context works for external callers, and the long-standing seams at block boundaries and non-unity aspect ratio issues are fixed (https://github.com/yt-project/yt_idv/pull/247, https://github.com/yt-project/yt_idv/pull/282, https://github.com/yt-project/yt_idv/pull/286).

0.5.0

Highlights

Spherical Coordinates! With this release, yt_idv can now volume render yt datasets defined in spherical coordinates. To use it, just try to load a 3D spherical dataset (gridded AMR and uniform grids only at present) and let us know if it breaks! For an overview of how it works, see the docs here or try out the new example scripts: spherical_unigrid_rendering.py and spherical_amr_rendering_with_refinement. Changes in 159, stay tuned for a paper…

More colormaps! In 154 and 155, many more colormaps were added to the colormap dropdown, including all of the colormaps from cmyt.
