What are the best ways to use 3D scanning data to create digital doubles for film and video games?

1 Choosing the right 3D scanner

The first step to create digital doubles is to choose the right 3D scanner for your project. Depending on your budget, time, and quality requirements, you can choose from different types of 3D scanners, such as laser, structured light, photogrammetry, or lidar. Each type has its own advantages and disadvantages, such as accuracy, speed, resolution, portability, and cost. You should also consider the size and shape of the objects you want to scan, as some scanners may have limitations or challenges in capturing certain features.

3 Optimizing the 3D scanning process

The third step is to optimize the 3D scanning process to get the best results. This means following the instructions and best practices of your chosen scanner, such as setting the appropriate distance, angle, and speed of scanning. You should also check the quality and completeness of the scan as you go, and rescan any missing or noisy areas. Furthermore, you should scan the objects from multiple perspectives and angles, to capture as much detail and information as possible.

4 Processing the 3D scanning data

The fourth step is to process the 3D scanning data to make it ready for use. This means importing the data into a 3D software, such as Blender, Maya, or ZBrush, and performing some tasks, such as cleaning, aligning, merging, and smoothing the scans. You may also need to reduce the polygon count, fix the holes, or retopologize the mesh, to make it more suitable for animation and rendering. Additionally, you should apply some texture and color correction, to enhance the realism and appearance of the scan.

5 Adding details and enhancements

The fifth step is to add details and enhancements to the 3D scan, to make it more lifelike and expressive. This means sculpting, painting, or editing some features, such as hair, eyes, skin, wrinkles, or scars, to match the reference or artistic vision. You may also need to add some accessories, clothing, or props, to complement the character or scene. Furthermore, you should rig, skin, and pose the 3D scan, to give it some movement and personality.

6 Testing and exporting the 3D scan

The final step is to test and export the 3D scan, to make it compatible and usable for your film or video game. This means checking the quality and performance of the 3D scan, such as the resolution, texture, lighting, and animation. You may also need to adjust some settings, such as the scale, orientation, or format, to fit the specifications and requirements of your project. Additionally, you should export the 3D scan as a file or asset, such as an OBJ, FBX, or USDZ, and import it into your film or video game software, such as Unreal Engine, Unity, or Cinema 4D.
