PBVR 2.1（2023/03/27）

The latest version of PBVR 2.1 is available. In this update, the CS/IS-PBVR client program now supports Qt6 (Mac ARM architecture).

Remote VR Visualization System VR-PBVR 1.0 (2023/03/29)

Remote visualization software PBVR (CS-PBVR) compresses large data on remote storage into particle data and transfers it to a user PC for efficient visualization.

VR-PBVR is an extension of CS-PBVR's visualization functionality for the Oculus head-mounted display. This enables interactive VR visualization of large-scale data stored on remote storage on a PC at hand.

PBVR 2.0 (December 12, 2022)

The latest version of PBVR 2.0 is available. In this update, source codes of CS/IS-PBVR’s client are integrated, and pre-defined colormaps are updated.

The minor update version of PBVR 1.173 is available. It is bug fix of Metropolis sampling which is a kind of sampling method.

PBVR 1.17.2 (May 26, 2022)

The minor update version of PBVR 1.172 is available. In addition to the previous GPU renderer version, this update releases a CPU renderer version for use in supercomputer front-end servers.

PBVR 1.17.1 (January 31, 2022)

The minor updated version of PBVR 1.17.1 is available. In this update, a bug of the polygon composition was fixed.

PBVR 1.17 (January 4, 2022)

In this update, composition of the volume rendering and polygon rendering for the boundary shape become possible.
Source code, binaries, and documentation for both the updated built-in filter and the legacy separate filter are available.

PBVR 1.16 (July 27, 2021)

In this update, the client program of the filter built-in version is constructed by Qt. This version can read and visualize the volume data without filtering.

With this update, the GPU renderer is now available and can be switched to the CPU renderer.

PBVR 1.13.1 (October 21, 2020)

Until now, PBVR has been using the built-in visualization library, but PBVR 1.13.1 uses the KVS visualization library to support the visualization library update.

Histogram and Min/Max value in transfer function editor is modified.

PBVR 1.13 (September 16, 2020)

Until now, PBVR has been using the built-in visualization library, but PBVR 1.13 uses the KVS visualization library to support the visualization library update.

PBVR 1.12 (June 12, 2020)

The GUI of this program has been updated from version 1.11.

This update fixes the following point.

・ Renewed the GUI that was built with OpenGL before version 1.11 to Qt.

PBVR 1.11 (March 15, 2019)

This release is update of previous 1.10. In this release, both of non-filtered PBVR suited to visualize GB scale data and filtered PBVR suited to visualize TB scale data are released.

In addition, the following points have been corrected in this update.

・ Unification of transfer function editors for non-filtered PBVR and filtered PBVR.
・ Fixed warnings of KVS library at compile.
・ Fixed memory leak and undefined behavior in particle data merge using particle merge panel.

Version 1.10 (September 25, 2017)

This release added some new functions to the 1.09 release.

Some of the new functions of this release are:

• Filter program and Server program are connected into single program, and it can visualize input data without filter pre-processing.
• Parameters of initial camera position was changed from LookAt vector to Rotation, Translation, and Scaling vector.

Version 1.09a (May 16, 2017)

This release is bug fix version of the 1.09 release.

The fixed point is following:

【Server】
• Modified a bug for the synthesize operation of the color function.

Version 1.09 (March 8, 2017)

This release added some new functions to the 1.08b release.

Some of the new functions of this release are:

【Server】
• Enabled to process multiple volume data stored in distributed environment.

【Client】
• Enabled to control how to display the legend bar.
• Enabled to specify coordinate axis.
• Enabled to control viewer.

Version 1.08b (August 26, 2016)

This is a fixed release that addresses some issues reported in the 1.08a release.

The issue addressed by this release is:

【Client】
• A color map editor (control point) is enabled to input a real number with a range from 0 to1.

Version 1.08a (July 4, 2016)

This is a fixed release that addresses some issues reported in the 1.08 release.

Some of the issues addressed by this release are:

【Filter】
• The filter program couldn’t read AVSUCD binary data on ICEX. Now fixed.
• Filtering process for the multiple elemental data didn’t finish. Now fixed.
• STL dataset couldn’t processed with MPI. Fixed that.

【Server】
• Transfer function default ranges are set to min/max values of first time step.
• The number of particles over the particle limit was generated. Now fixed.
• The number of particles generated in the Client/Server mode and the Batch mode were different. Now fixed.

【Client】
• Time step animation automatically started after launching. Fixed to start the animation after pushing “Start” button.
• If no parameter file is specified for launching, the default values of transfer function editor panel didn’t reflect to the particle generation. Now fixed.
• Modified to allow “_” for prefix of kvsml file name in the Stand alone mode.
