How is Gaussian Splatting different from photogrammetry?
Photogrammetry builds polygon meshes; Gaussian Splatting renders soft visual Gaussians.
Traditional photogrammetry reconstructs surfaces and textures. It is useful when you need geometry, measurements, mesh editing, or CAD-style output. Gaussian Splatting focuses on reproducing visual appearance from viewpoints, which often makes it stronger for photorealistic viewing and virtual tours.
Splatware can help bridge the difference by creating high-fidelity splats and also providing dense mesh options when geometry is needed.
Gaussian Splatting vs photogrammetry
| Need | Better fit | Reason |
|---|---|---|
| Realistic web viewing | Gaussian Splatting | High visual fidelity and real-time interaction. |
| Clean polygon mesh | Photogrammetry | Meshes are editable and geometry-based. |
| Virtual tour | Gaussian Splatting | More natural visual appearance. |
| Collision or physics | Mesh / dense mesh | Splats are not collision geometry. |
| Drone visual reconstruction | Gaussian Splatting | Strong for photorealistic site capture. |
| Measurement workflow | Photogrammetry or mesh | Better geometry basis. |
What is NeRF vs Gaussian Splatting?
NeRF uses a neural network for radiance field rendering, while Gaussian Splatting uses explicit optimized 3D Gaussians.
NeRFs were a major step in neural view synthesis. They can create impressive novel views from photos, but classic NeRF workflows can be slower to train and render because they rely on neural network evaluation.
Gaussian Splatting keeps a renderable set of explicit primitives. This makes real-time rendering more practical and helps explain why 3DGS became popular for browsers, tours, and interactive capture.
Does Gaussian Splatting use AI or machine learning?
Gaussian Splatting uses optimization and differentiable rendering techniques, but the final scene is usually an explicit set of Gaussian primitives rather than only a neural network.
People often ask whether Gaussian Splatting is AI. The best answer is nuanced: the training process uses data-driven optimization, and some tools add AI features such as segmentation or cleanup, but the final 3DGS file is a structured scene representation of Gaussian splats.
Splatware also includes production tools such as AI-style segmentation options, training analytics, editor cleanup, and converter workflows around the splat output.
Does Gaussian Splatting use ray tracing?
Standard real-time Gaussian Splatting rendering does not rely on ray tracing; it usually uses GPU rasterization and blending of projected splats.
This is one reason Gaussian Splatting can be fast. The renderer projects many soft blobs onto the screen and blends them, instead of tracing rays through geometry or running a neural network for every pixel.
Which should you choose?
Choose Gaussian Splatting for photorealistic interactive viewing, photogrammetry for mesh geometry, and NeRF for neural rendering research or specific pipelines.

Frequently asked questions
Is Gaussian Splatting better than photogrammetry?
It is better for photorealistic interactive viewing, but photogrammetry is better for clean polygon mesh geometry.
What is NeRF vs Gaussian Splatting?
NeRF uses a neural network to represent the radiance field, while Gaussian Splatting uses explicit 3D Gaussian primitives that render faster in many real-time workflows.
Is Gaussian Splatting real time?
Yes, optimized Gaussian Splatting scenes can render in real time using GPU rasterization.
Does Gaussian Splatting use ray tracing?
Usually no. Real-time 3DGS primarily rasterizes and blends splats rather than ray tracing.
Does Gaussian Splatting use machine learning?
The training uses data-driven optimization, but the final model is an explicit splat representation.
What is the difference between 3D mesh and Gaussian Splatting?
A mesh is made of polygon surfaces. Gaussian Splatting is made of many soft 3D Gaussian ellipsoids that reproduce visual appearance.
Which is best for virtual tours?
Gaussian Splatting is often best for photorealistic virtual tours; Splatware can host and build tour workflows.
Which is best for physics?
A mesh or dense mesh output is best for physics. Splatware can provide dense mesh options alongside splats.
