Support for Gaussian Splatting models in the 3D tab (Upgrade) 

What is Gaussian Splatting and Why is it Revolutionary?

Gaussian Splatting is an innovative technology that creates hyper-realistic 3D models using points instead of traditional polygons. This ensures a faithful representation of materials, textures, and reflections, resulting in lighter, more detailed, and dynamic models.

Benefits Over Traditional Photogrammetry

  • Superior Visual Quality: It captures materials, transparencies, and reflections with exceptional realism, accurately mimicking the behavior of light.
  • Reduced File Size: Models are up to 10 times lighter than traditional GLB files, making them easier to use and distribute.
  • Precise Measurements: Enables exact measurements directly on the 3D model, ideal for technical analysis and planning.
  • Solving Complex Challenges: Gaussian Splatting overcomes common issues in traditional photogrammetry when capturing transparent or reflective elements, which often produced erroneous and unusable surfaces.

Applications Across Multiple Industries

Gaussian Splatting is a key tool for industries such as architecture, engineering, e-commerce, tourism, cultural heritage, real estate, and design, allowing projects, products, and spaces to be visualized with unparalleled detail.

The Potential Combined with 3DVista VT Pro

When integrated with 3DVista VT Pro, this technology reaches its full potential:

  • Multimedia Integration: Combines Gaussian Splatting models with traditional panoramas to leverage the best of both worlds.
  • Exploration Flexibility: Explore models in Fly Over, Orbital, and First Person modes, adapting to the needs of each project.
  • Advanced Interactivity: Interact with hotspots, take precise measurements, and access key data directly on the 3D model.
  • Temporal Analysis: Visualize and compare different stages of a project through interactive timelines.

Gaussian Splatting, combined with 3DVista VT Pro, redefines how we view and interact with the digital world, delivering more realistic, precise, and efficient 3D experiences than ever before. 

VT Pro supports the PLY format (compatible with the official paper) and SPLAT formats.

«Dynamic Resolution» option for 3D Models (Upgrade)

We are adding the «Dynamic Resolution» feature to our software, a tool designed to improve the performance of 3D models. This option, available in the 3D model settings, automatically adjusts the model's quality when a drop in framerate is detected, ensuring a smoother experience.

When device performance is limited, the model’s quality is temporarily reduced to maintain fast and uninterrupted interaction. Once the framerate returns to optimal levels, the model automatically restores its original quality without user intervention.

This functionality is especially useful for handling complex 3D models on devices with limited resources or in demanding situations, allowing for smooth navigation without losing interactivity. With «Dynamic Resolution,» we ensure a more accessible and optimized experience for all users, regardless of device capabilities.

«Double Click Action» option for the Orbit camera in 3D Models (Upgrade)

We’ve added the «Double Click Action» option to the orbit camera in 3D models. This feature allows you to center the camera pivot with a simple double-click, enabling more precise and fluid navigation around the model.

This small adjustment significantly enhances the interactive experience, making it much easier to explore and focus on specific details intuitively.

New option: «VR Menu» for 3D Models

The «VR Menu» is now available for 3D models. Previously, this functionality could only be activated in panoramas, but now VR device users can enjoy the same interactive experience with this type of media.

The «VR Menu» appears when looking up in a VR device, allowing easy access to navigation options. To activate and configure it, simply go to the Project / Playlist tab in the right panel, within the VR Settings section, and check the «Show VR Menu» option. Additional menu settings can be adjusted by clicking on the gear icon next to it.

With this improvement, navigating 3D models in VR environments becomes even more fluid and accessible.

New Option: «Min/Max Yaw/Pitch» Settings for the Fly Over Camera in 3D Models

The «Min/Max Yaw/Pitch» settings have been added for the Fly Over camera in 3D models. This new functionality allows you to limit the horizontal (Yaw) and vertical (Pitch) angles of the camera, providing greater control over movements and preventing unwanted displacements.

This option is particularly useful for restricting navigation to specific areas or ensuring a more guided and precise viewing experience in 3D models. You can find this setting in the Camera Settings, under the «Advanced Options» section.

New Option: «At End Repetition» Event in Live Panorama

The «At End Repetition» event has been added to Live Panorama, which triggers at the end of each loop cycle. For example, you can use it to display a message or activate a hotspot every time the transition reaches the end of the last panorama in each repetition. This functionality provides greater control and customization in the interactive experience.

New Option: «Keep 3D Model Loaded Without Location»

The «Keep 3D Model Loaded Without Location» option has been added to the Panorama tab within the 3D Model settings. This feature allows the 3D model to remain in memory even when visiting an unlinked panorama.

This improves performance by eliminating the need to reload the model when returning to it from a panorama, ensuring faster and smoother transitions between different media.

New Default Format: WebP for New Projects

Thanks to the advantages offered by the WebP format, such as a significant reduction in file size compared to traditional formats like JPG or PNG, it will now be the default format for images in new projects. This not only optimizes tour performance by reducing loading times but also lowers hosting space usage, resulting in savings on storage costs. (Compatible with the 2023.0 update).
