Particle-Based Remote Visualization Applications: PBVR
(Particle-Based Volume Rendering)

Selection of remote visualization method

You can choose between Client Server (CS) visualization for visualizing volume data stored in remote storage, or In-Situ (IS) visualization for simultaneous, co-environment visualization of simulations. CS visualization supports a variety of data formats used in the fluids field, such as VTK, CGNS, and EnSight. Click here for more information on IS mode of PBVR.

Visualize large-scale data at high speed

The particle generation process on servers and supercomputers is optimized for parallel environments, and large volume data can be converted into particles for visualization in seconds. Particle data can be freely viewed, and can be rendered at an interactive frame rate using the GPU.

Visualization capabilities for multivariate data

Each variate of the volume data can be synthesized with an algebraic expression to define a new variable. In addition, functions that assign color and opacity to variables can be synthesized with algebraic expressions to design visualizations for multivariates.

Visualization of 3D point clouds

It is possible to visualize 3D point clouds acquired by photogrammetry and LiDAR. The 3D point cloud can be integrated with the volume data of the simulation results.

VR Visualization Capabilities

A head-mounted display (HMD) for VR visualization can be selected as the display device for VR visualization. Since this function is implemented using the HMD standard OpenXR, it works universally on various HMDs such as Meta Quest and HTC Vive.

Release Notes

PBVR 3.2.0 (2024/11/12)

PBVR 3.2.0 is now available for download. This update allows the VR display feature to be used in both CS and IS remote visualization modes. Additionally, by implementing the OpenXR standard, widely used in HMDs, PBVR 3.2.0 operates universally across currently available HMDs. HMDs that have been confirmed to work are as follows.

• ・ Meta Quest2
• ・ Meta Ques3
• ・ VIVE Pro
• ・ VIVE Focus3
• ・ PICO4

The source code, manual, and binaries are available on github.

PBVR 3.1.0 (2024/10/7)

PBVR3.1.0 is available for download. In this update, the GUI of CS-PBVR and IS-PBVR has been unified, allowing users to select the communication mode (Client-Server or In-Situ) from the Connection panel. With this integration, the visualization features of CS-PBVR can now also be used in IS-PBVR.

The source code, manual, and binaries are available on github.

PBVR 3.0.0 (2024/09/18)

PBVR3.0.0 is available for download. In this update, the GUI of the CS-PBVR client program has been redesigned. In addition to the LAS format for 3D point cloud data, the PTS format is now supported. In addition, we have added a Merge panel function that allows you to freely add, display, and delete multiple volume data and point cloud data on the GUI.

The source code, manual, and binaries are available on github.

Multi location IS-PBVR 1.0.0 (2024/03/01)

Multi location IS-PBVR 1.0.0 (ML PBVR), which extends IS PBVR for remote collaborative visualization at multiple locations, is available for download. ML PBVR can visualize large-scale simulations on a remote supercomputer on a PC at the same time as calculations. The visualization can then be shared across multiple PCs connected to a supercomputer. ML PBVR is capable of VR visualization using HMD, and interactive analysis between users is possible by changing the visualization parameters by multiple users.

The source code is available on github.

VR CS-PBVR 2.2.1 (2023/11/29)

You can download the VR CS-PBVR, which enables VR visualization using the HMD as a display device for CS-PBVR.

The source code and manual are available on github.
https://github.com/CCSEPBVR/CS-IS-PBVR/tree/release_cs_is_pbvr_v2.2.1

IS PBVR 2.2.0 (2023/11/10)

IS-PBVR 2.2.0 is available for download. In this version, it is now possible to add textured polygon data and 3D point clouds (LAS format) from the IS PBVR client program for integrated display.

The source code is available on github.
