(adapted from Ascent's Changelog )

0.9.4 Release Highlights

(adapted from Ascent's Changelog )

Released 2025-07-18

Preferred dependency versions for ascent@develop

Added

  • Added ability to specify either fields (list of strings) or field (string) for uniform grid sample filter
  • Added a sample filter that allows you to sample field values at a list of explicit points or along a line.
  • Added use case to vtkh data adaptor for blueprint meshes with explicit mesh coordinates with implicit topology (a blueprint structured mesh).
  • Added a compressed color table format.
  • Added action options relating to logging functionality including open_log, flush_log, and close_log to toggle logging as well as set_log_threshold and set_echo_threshold to control logging and standard output levels.
  • Added a new unified logging infrastructure.
  • Added support for unstructured topologies with mixed elements types (for example, hexs and tets).
  • Added support for pyramid and wedge elements.
  • Added sphere, cylinder, box, and plane options to the slice filter.
  • Added a topologies option to the relay extract. This allows you to select which topologies are saved. This option can be used with the existing fields option, the result is the union of the selected topologies and fields.
  • Added near_plane and far_plane to the camera details provided in Ascent::info()
  • Added add_mpi_ranks and add_domain_ids filters for adding rank and domain fields to a mesh
  • Added transform filter, which allows you to rotate, scale, reflect, translate, mesh coordinates
  • Added python script in src/utilities/visit_session_converters to convert VisIt color table to Ascent actions color table
  • Added fields option to the project 2d to support scalar rendering of specific fields.
  • Added dataset_bounds option to the project 2d, which can be used instead of a full 3D camera specification
  • Added support for triggers to execute actions from multiple files via an actions_files option that takes a list of actions files.
  • Added an external_surfaces transform filter, that can be used to reduce memory requirements in pipelines where you plan to only process the external faces of a data set.
  • Added a declare_fields action, that allows users to explicitly list the fields to return for field filtering. This option avoids complex field parsing logic.
  • Added a 2d camera mode (camera/2d: [left, right, bottom, top]) to scene render cameras and the project_2d (scalar rendering) filter cameras.
  • Added support for include keyword to include children from yaml files in an input node trees
  • Added support for special keyword formatting for output paths. Current supported keywords include
    cycle, family, and time.
  • Added support for formatting of output paths for extracts.
  • Added support for parallel timestep mode to replay allowing for parallel in time processes in addition to pre-existing distributed-memory parallelism.

Changed

  • Extensive improvements to Rover X Ray Ray Tracing Diagnostic features (the xray extract).
  • Changed the replay utility's binary names such that replay_ser is now ascent_replay and raplay_mpi is now ascent_replay_mpi. This will help prevent potential name collisions with other tools that also have replay utilities.
  • Updated several preferred tpl versions
  • Changed bounding box used for default scene bounds to be the union of all topologies used in scene plots. Perviously, the union of all topologies in the dataset where used.

Fixed

  • Fixed WarpX filter that was not allowing for rendering of the output streamlines
  • Fixed Uniform Grid bug only accepting 2D slices along the Z-axis.
  • Resolved a few cases where MPI_COMM_WORLD was used instead instead of the selected MPI communicator.
  • Resolved a bug where a sharing a coordset between multiple polytopal topologies would corrupt mesh processing.
  • Fixed a bug with Cinema resource output that could lead to corrupted html results.
  • Fixed a bug where controls for world and screen annotations where ignored in Cinema renders.
  • Fixed a bug in Uniform Grid Sampling and changed how ties for valid points are broken.

0.9.3 Release Highlights (2024-05-11)

(adapted from Ascent's Changelog )

Preferred dependency versions for [email protected]

Added

  • Added a uniform grid resampling filter.
  • Added refinement_level option to Relay Extract. When used this will refine high order meshes to a low order representation and save the low order result as the extract data.
  • Added parameters to control HDF5 compression options to the Relay Extract.
  • Added check to make sure all domain IDs are unique
  • Added a vtk extract that saves each mesh domain to a legacy vtk file grouped, with all domain data grouped by a .visit file.
  • Added particle advection for streamline and related rendering support.
  • Added WarpX Streamline filter that uses charged particles.
  • Added seed population options for particle advection: point, point list, line, and box
  • Added more Ascent tutorial examples
  • Added support for implicit points style Blueprint input meshes
  • Added actions for shell commands and simulation code function callbacks
  • Added a cylinder option to the clip filter.
  • Added box, plane, cylinder, and sphere options to the Threshold filter, enabling sub selecting a mesh spatially.

Changed

  • Changed the Data Binning filter to accept a reduction_field parameter (instead of var), and similarly the axis parameters to take field (instead of var). The var style parameters are still accepted, but deprecated and will be removed in a future release.
  • Changed the Streamline and WarpXStreamline filters to apply the VTK-m Tube filter to their outputs, allowing for the results to be rendered.
  • Updated CMake Python build infrastructure to use

Fixed

  • Various small bug fixes

0.9.2 Release Highlights

(adapted from Ascent's Changelog )

Preferred dependency versions for [email protected]

Added

  • Automatic camera placement render that uses different types of entropy (data, depth, shading).
  • Scene/Render option to manually position color bars

(adapted from Ascent's Changelog )

Preferred dependency versions for [email protected]

Added

  • Added support for building and running on Windows.
  • Added runtime control option (in addition to existing compile time option) to Devil Ray stats.
  • Added CI testing for building Ascent and required third-party libs on Windows.

  • Added option to build Ascent with only Devil Ray support

Fixed

  • Fixed a MPI hang if actions files (yaml or json) fail to parse

Changed

  • To better support installs that are relocated on the file system, Cinema database file resources are now compiled into the Ascent library.
  • Updated to use Babelflow (1.0.1) and Parallel Merge Tree (1.0.2).
