Kiri Engine: Create 3D Models from Photos with Your Mobile
The Kiri Engine app democratizes access to photogrammetry, allowing the generation of complete three-dimensional models using only a smartphone camera. It transforms a sequence of common images into a 3D mesh with realistic textures ready for use in various projects. 📱➡️🧊
The Core of the Process: From Images to Geometry
The system works by applying computer vision algorithms. It analyzes multiple photographs of the same object, taken from different perspectives, to identify matching points. Through triangulation, it calculates the exact position of these points in space, thus building the base geometric mesh. Subsequently, it automatically projects the colors and details from the original photos onto this mesh to create the final texture.
Keys to Successful Reconstruction:- The object must remain completely static throughout the photo session.
- A neutral background and uniform lighting without sudden changes are required.
- It is crucial to avoid reflective, shiny, or transparent surfaces.
Photogrammetry is not magic, it's mathematics. The quality of the input data (your photos) directly determines the quality of the output 3D model.
Avoiding Common Capture Errors
A common mistake is not photographing the object from all possible angles. Many users rotate around at horizontal level but forget to take photos from high and low positions. This results in incomplete models with holes at the top and bottom poles, similar to a donut.
Tips for Complete Coverage:- Take many photographs, ensuring that each new image overlaps by 60-80% with the previous one.
- Cover the entire surface of the object, including views from above and below.
- Move the camera around the object, do not rotate the object in front of the camera.
Results and Applications
After processing, Kiri Engine delivers a textured 3D model that can be exported in standard formats. This resource is immediately usable in design software, video games, AR/VR, or 3D printing, offering a fast and accessible way to digitize real-world objects. The final success largely depends on meticulously following the capture guidelines. 🎯
