Comparing the Top 5 3D Scanner Apps:

If you're diving into the world of 3D scanning, choosing the right app can make all the difference. In this quick guide, we'll explore the top five 3D scanning apps and what makes each one special, analyzing their strengths and weaknesses in terms of the 4 popular 3D scanning methods: Photogrammetry, NeRF, 3D Gaussian Splatting, and LiDAR. Whether you're a professional or a hobbyist, there's an app here for you.

KIRI Engine

KIRI Engine has a great advantage in terms of photogrammetry and Neural Radiance Fields (adjusted for mesh production: NSR), both delivering high-quality 3D scans. It excels in capturing detailed and feature-rich objects, offering features like object masking, PBR textures, multiple export options, and QuadMesh retopology. KIRI Engine also offers advanced 3D Gaussian Splatting with the ability to not only edit the point-cloud file, but also to export the Gaussian Splats as OBJ files.

Additionally, KIRI integrated LiDAR scanning methods for those with LiDAR equipped iOS devices on top of its cloud algorithms, including Room Scan, Scene Scan, and Object Capture. The versatility in scanning methods makes KIRI Engine a top choice for various scanning needs.

Polycam

Polycam supports photogrammetry, 3D Gaussian Splatting, and LiDAR, making it a robust option for those with LiDAR-equipped iPhones. Its real-time feedback and fast processing speed are standout features. Polycam also supports object masking, making it user-friendly and efficient for different projects.

RealityScan

RealityScan focuses solely on photogrammetry, providing an intuitive user experience with a sleek interface. It allows for efficient photo uploads during scanning. While it offers a high face count in models, it lacks the object masking feature, which isolates the scanned object, that is commonly available in other apps. It's recommended for direct integration into Unreal Engine as this tool is developed and operated by Epic Games.

Luma

Luma leverages NeRF and 3D Gaussian Splatting technologies to scan complex and simple objects with ease. The algorithms are largely backed up by its machine learning model, granting accuracy and definition. Its algorithm ensures high-quality models, but it is limited to iOS devices and cannot capture the bottom of objects. Despite these limitations, Luma excels at detailed scans of intricate objects.

Scaniverse

Scaniverse is a practical choice for quick scans on iOS devices, utilizing LiDAR for real-time feedback. It's especially handy for users with iPhone Pro models, offering local processing and ease of use. However, it delivers lower face counts and struggles with shiny surfaces.

Each app has its unique strengths tailored to different usage. The saturated market of 3D scanning tools provide users with an abundance of selections for various 3D scanning solutions.

All and all, KIRI Engine stands out for its versatility and high-quality outputs, making it a fantastic all-around choice. Whether you're scanning for professional use or personal projects, KIRI Engine provides the wide range of scanning methods to suit your needs.
