2402 10002 MM-Point: Multi-View Information-Enhanced Multi-Modal Self-Supervised 3D Point Cloud Understanding

In this paper, we described our interactive hybrid 2D and 3D visual analytics application that allows the user to analyze and visualize data from our Monte Carlo simulation. Our data centric design allows the user to visualize the 2D and 3D data of the data set on both the LHRD and Microsoft HoloLens Mixed Reality system. This gives the user the capability to visualize 2D data on a 2D LHRD platform and 3D data using 3D mixed reality technology. The exploration, modeling and analysis of complex heterogeneous data require a vastly different class of tools capable of supporting data-centric, user-centric, visualization algorithm and systems agnostic visual analytics.

Statistical infographics focus on presenting data and numbers in a visually appealing way. They typically include charts, graphs, and percentages to break down complex information. This type of 2D infographic is ideal for marketing campaigns that rely on data-driven results, making the information easier to digest for the audience. Infographics are both informative and visually appealing, making the information easier to remember. When people see well-designed visuals, they are more likely to remember the data presented. This helps businesses communicate important messages in a way that sticks with their audience, adding long-term value.

The following subsections describe in greater detail on the work related to SAGE2 framework and ParaViewWeb that provided the basic building blocks we used in the development of our 2D visualization application on our LHRD. Hybrid 2D and 3D visual analytics of our Monte Carlo simulation with the monitor to the right of the Large High Resolution Display system showing the view of the user on the Microsoft HoloLens Mixed Reality device. For the questionnaire (as listed in the Appendix), we ask the users 10 questions total.

They form the building blocks of the UI and are solely concerned with the rendering aspects of that particular component. In order to be a ParaViewWeb component, it must implement a small number of functions that provide the interface that ParaViewWeb expects, and so other charting libraries can be made into a component by creating this interface. As mentioned previously, they will receive events from the providers, and update their views appropriately. Maintaining consistent colors, fonts, and style is essential to keep your infographic visually cohesive. This consistency will make your work more recognizable and professional, especially when creating 2D animated infographics for marketing. Each type of 2D infographic has its strengths, depending on your communication needs.

User interaction on the 2D visualization running on the LHRD will cause the 3D visualization displayed on the Microsoft HoloLens to update accordingly. As mentioned in the previous sections, we primarily utilize WAMP connections to pass information among separate system applications. Unfortunately, the current stable .NET version available for Unity does not support the desired WAMP libraries to establish bidirectional communication between our Unity application and the application server.

However, the advantage with this approach is that it allows for quicker prototyping of specific reconfigurable visualization use cases, as data can be managed more flexibly. Refer to the prototype examples in the subsequent sections to see an illustration of how the application server can be utilized and extended for different hybrid, distributed visualization applications. They make complex data easier to understand and can enhance clarity in marketing campaigns and reports.

Datasets

For the 2D visualization displayed on a monitor and the 3D visualization on the mixed reality environment with multiple coordinated view, the user can look around the 3D scene in mixed reality mode for a 3D immersive visualization. For this environment, the time slider interaction on the 2D view will update the data range for both 2D and 3D views. For 3D assets with geospatial and temporal attributes, the most intuitive means to understand the data is through a 3D animation of the attributes. Unity development platform was used to develop our 3D visualization applications as it is a very powerful tool for creating high-end 3D graphics applications that can be deployed to various hardware platforms and devices. There is also a multitude of SDKs that may be imported into a Unity development environment to greatly speedup the application development. Therefore, Unity development platform is a very attractive option for creating interactive 3D visualization applications and simulations.

Besides static infographics, 2D infographic videos are also gaining popularity, especially on social media. Since these formats are highly customizable, they can fit any brand strategy while providing high-quality visuals. This helps brands better communicate with their audience and improve the customer experience. Although SyncVis applications are web-based application that can run in a normal browser, several UI decisions were made with the purpose of running the application on a LHRD to support a large number of coordinated visualizations. We utilize SAGE2 on our LHRD to run SyncVis applications, which supports running web applications through its WebView application as mentioned in the related work section. Furthermore, the ParaViewWeb library implements a collection of visualization components that is responsible for rendering the views.

Various combinations of hardware and software platforms can be leveraged in the development of visual analytics tools. However, the most challenging design effort is to develop a visual analytics application for our requirements while considering the extensible and general-purpose aspect of the tool to support the next phase of the research. Specifically in our work, our goal is to support real-time interactive visualization of complex data through useful human-computer interaction on Large High-Resolution Display (LHRD) and 3D Mixed Reality systems.

Our visual analytics system architecture is designed to streamline the visual information seeking Mantra to allow for a much easier interoperability of visualization hardware and software to support unified data analysis JSViz tasks. This architecture can be used to create many custom hybrid data visualization systems. In the prototypes that we present here, we developed a hybrid 2D and 3D visualization application.

The SAGE2 framework combines the multiple displays into one large workspace, allowing multiple users to connect via a modern browser over the network. SAGE2 software runs on the head node of our cluster, and launches a web server with the configuration of the client machines to host the display clients. The UI clients are how the users connect to the environment, by typing the URL of the web server into a modern browser.

To create impactful 2D infographics, choose strong visuals that complement the information. Whether you’re working with icons, illustrations, or 2D animated infographics, ensure your visuals highlight the key points without overshadowing the data. Comparison infographics are used to put two or more options side by side for easy evaluation. By using simple visuals, they help audiences see the differences and similarities quickly, supporting better decision-making.
