3D Scanner App KIRI Engine: The Best 3D Model Scanning Software

Traditional physical 3D scanners often come with several drawbacks. They typically require expensive and bulky hardware, such as laser scanners or structured light systems, which can be complicated to set up and use. Additionally, these scanners may struggle with certain materials, such as reflective or transparent surfaces, leading to incomplete or inaccurate scans. The process can also be time-consuming, requiring careful calibration and controlled environments to achieve optimal results.

KIRI Engine, on the other hand, revolutionizes 3D scanning by eliminating these limitations. Instead of relying on costly hardware, it uses advanced photogrammetry technology to generate high-quality 3D models from nothing more than multi-angle photos or videos. The results are not only highly detailed but also feature rich, accurate textures—often surpassing the output of traditional 3D scanners. Whether capturing intricate textures or preserving fine details, KIRI Engine delivers outstanding performance, proving that professional-grade 3D scanning is now more accessible than ever.

Featureless Object Scan

Traditional photogrammetry struggles with scanning objects that are shiny, reflective, or transparent due to the way light interacts with these surfaces. KIRI Engine's Featureless Object Scan is designed to solve this challenge using an advanced AI-powered approach, ensuring high-quality 3D scans even for objects that conventional methods fail to capture.

Powered by Neural Surface Reconstruction (NSR), this technology allows users to scan objects regardless of texture or reflectivity. For transparent materials, the algorithm analyzes both the object and its background to reconstruct an accurate surface mesh. When dealing with reflective surfaces, it interprets the object as a whole rather than relying on distinct surface features. For smooth, solid-color objects, the scan intelligently processes the entire scene to generate a precise 3D model.

Featureless Object Scan integrates principles from Neural Radiance Fields (NeRFs), a technique typically used for 3D visualization without meshes. By learning from NeRF-based algorithms, KIRI Engine produces detailed, structured mesh outputs from radiance field data, making it possible to scan nearly anything with exceptional accuracy. With this breakthrough technology, KIRI Engine redefines what's possible in 3D scanning, allowing users to capture even the most challenging objects effortlessly.

3D Gaussian Splatting Scan

3DGS Scan is one of the most advanced technologies in KIRI Engine, delivering a revolutionary way to capture and visualize 3D environments with unmatched speed and accuracy. Unlike traditional 3D scanning methods that rely on mesh reconstruction and texture mapping, 3D Gaussian Splatting (3DGS) generates dense point clouds directly from short video footage. These points are rendered dynamically, allowing for highly detailed, photorealistic 3D visualizations without the need for complex geometry.

By leveraging machine learning, 3DGS transforms point clouds into smooth and immersive visual representations. Each point is treated as a Gaussian, with color and opacity dynamically adjusted based on surrounding areas and viewing angles. This technique enables the precise preservation of entire scenes, making it especially useful for capturing objects with minimal surface features and complex environments.

To enhance its usability, KIRI Engine provides several advanced tools for working with 3DGS scans. The 3DGS to Mesh feature allows users to convert Gaussian splats into a structured 3D model, making it compatible with additional enhancements such as quad-mesh retopology, PBR texture generation, and auto-rigging. With 3DGS Masking, users can automatically remove backgrounds during processing, ensuring clean and isolated Gaussian splats ready for integration into rendering engines like Blender and Unreal Engine. Additionally, the 3DGS Blender Plugin offers seamless rendering and editing of Gaussian splats within Blender, providing a streamlined workflow for artists and developers.

Despite being a cutting-edge technology, KIRI Engine's 3DGS Scan makes 3D Gaussian Splatting accessible to all, enabling users to create lifelike digital environments with ease.

Answer: After generating your 3D model in KIRI Engine, export it in a compatible format such as OBJ, FBX, STL, GLB, GLTF, USDZ, PLY, and XYZ. Then, import the file into Blender or Unity using their built-in import tools. For Blender, use "File > Import" and select the appropriate format. For Unity, drag and drop the file into the project's Assets folder for seamless integration.

Question: What are the best shooting techniques for 3D scanning?

Answer: Ensure even lighting to avoid harsh shadows or overexposure. Capture the object from multiple angles, maintaining a consistent distance. Avoid blurry or low-quality images by keeping the camera steady. For reflective or transparent objects, use a matte spray or adjust the environment to reduce reflections. The more angles you capture through photos or videos, the higher the scan quality, resulting in a more detailed and accurate 3D model.
