What is Gaussian splatting—and how does it work?

Traditional 3D modeling builds objects from polygons—triangles and quadrilaterals that are assembled into surfaces. This method is precise, controllable, and ideal for technical products. Gaussian splatting takes a fundamentally different approach: Instead of modeling polygons, the technology reconstructs a scene from a series of photos or videos as a cloud of millions of small, three-dimensional Gaussian functions—known as “splats.”

Each splat describes a small area of the scene, including its position, color, transparency, and shape. Together, millions of these splats create a photorealistic, volumetric representation that can be rendered in real time from any viewing angle—without pre-calculated images or long loading times.

Why Gaussian Splatting Is Getting So Much Attention Right Now

The technology quickly gained widespread recognition through publications by international research groups and has since revolutionized the 3D community in a lasting way. The reason: Gaussian Splatting delivers visual quality that far surpasses traditional photogrammetric methods such as NeRF (Neural Radiance Fields)—and does so in a fraction of the rendering time.

What used to take minutes or hours now happens seamlessly in real time. And what used to require time-consuming manual modeling is now generated automatically from a mathematically optimized set of photos. This fundamentally changes how quickly and cost-effectively real-world objects and environments can be digitized.

An Overview of the Advantages of Gaussian Splatting

• Photorealism from real-world footage: Objects and spaces are reconstructed directly from photos or videos—complete with all the details, light reflections, and textures of the original.
• Render: The finished scene can be viewed in real time from any angle—ideal for interactive web applications and virtual tours.
• Quick digitization: A product or room can be photographed with a smartphone and quickly converted into an interactive 3D model.
• High level of detail: Complex surfaces, organic shapes, and natural materials are reconstructed with a level of detail that is virtually impossible to achieve through manual modeling.
• Browser-based rendering: Gaussian splatting models can increasingly be rendered directly in the browser—serving as the foundation for cutting-edge Web AR experiences that don't require a dedicated app.

Where Gaussian Splatting Reaches Its Limits

As impressive as the technology is, it is not a panacea. Gaussian splatting has specific weaknesses that are relevant for productive use in small and medium-sized businesses:

• No precise CAD basis: Gaussian Splatting reconstructs what the camera sees—not what is structurally correct. For technical product animations requiring exact dimensions, motion sequences, and cross-sectional views, traditional CGI based on CAD data remains the better choice.
• Limited editability: A Gaussian splatting scene is not as easy to edit as a traditional 3D model. Colors, materials, and configurations are more difficult to adjust.
• Dependence on image quality: The result is only as good as the original photograph. Poor lighting, motion blur, or incorrect perspective can lead to image errors (artifacts).
• File Size and Performance: Gaussian splatting models can become very large—which means they require precise optimization to ensure smooth performance on the mobile web.

Gaussian Splatting vs. Traditional CGI: When to Use Which

Which applications are already useful for small and medium-sized businesses today

For small and medium-sized businesses, Gaussian splatting is already practical and appealing in certain scenarios:

• Virtual Showrooms and Exhibition Spaces: Quickly digitize physical showrooms or trade show booths and offer them as interactive virtual tours.
• Real Estate and Interior Design: Photorealistic digitalization of spaces and objects—as a complement to traditional 3D renderings or for quick presentations.
• Product digitization for organic objects: Photorealistically digitize handmade products, natural materials, or complex surfaces that are difficult to model.
• Supplement to CAD-based animations: Using Gaussian splatting environments as realistic backdrops for traditionally modeled CGI products.

FAQ – Frequently Asked Questions About Gaussian Splatting

What is Gaussian Splatting?
Gaussian Splatting is an innovativeRender that reconstructs real objects or scenes from a series of photos or videos as a cloud of three-dimensional Gaussian functions and renders them photorealistically in real time—significantly faster and with greater detail than traditional polygon models.

What is the difference between Gaussian splatting and traditional 3D modeling?
Traditional 3D modeling involves manually constructing objects from polygons. Gaussian splatting automatically reconstructs scenes from real photos or videos, generating a volumetric point cloud that can be rendered in real time. The result is often more detailed, but the production process is less controllable than with manually modeled CAD-based scenes.

For which industries is Gaussian Splatting suitable in the SME sector?
Gaussian Splatting is particularly well-suited for the rapid digitization of real-world objects, spaces, or environments—such as virtual showrooms, product presentations, real estate visualizations, or interactive web experiences where photorealistic real-time rendering is a priority.

Does Gaussian Splatting Replace TraditionalRender?
No, Gaussian SplattingRender replace traditionalRender ; rather, it complements it. For CAD-based product visualizations, technical animations, and fully controllable scenes, traditional CGI remains the better choice. Gaussian Splatting excels when real-world objects or environments need to be digitized quickly and in high detail.

Can Gaussian Splatting be used for Web AR?
Yes, Gaussian Splatting models are increasingly being used for browser-based Web AR applications as well. The technology is evolving rapidly in this area and is opening up new possibilities for interactive product experiences without the need for an app.
