How to Export a 3D Model from Reality Capture

To export a 3D model from Reality Capture, navigate to the MESH MODEL tab and use the Dense Mesh Model button located in the Export section.

Exporting your high-quality 3D reconstructions from Reality Capture is a straightforward process, allowing you to use your models in various external applications or for further processing. The primary method involves utilizing the dedicated export function within the software's interface.

Here's a breakdown of the steps:

Step-by-Step Export Process

1. Locate the MESH MODEL Tab: In the Reality Capture interface, find and click on the MESH MODEL tab. This tab contains tools specifically related to your reconstructed mesh.
2. Access the Export Section: Within the MESH MODEL tab, look for the Export section.
3. Click Dense Mesh Model: In the Export section, click the Dense Mesh Model button. This action initiates the export process.
4. Choose Location and Format: A standard Windows Explorer window will appear. This is where you define:
   • File Name: Give your exported model a descriptive name.
   • Export Location: Select the folder on your computer where you want to save the file.
   • File Format: Choose the desired file format from the 'Save as type' dropdown menu. Reality Capture supports a variety of popular formats compatible with most 3D software.
5. Save and Configure Settings: After setting the name, location, and format, press the Save button. This doesn't immediately export the model but opens the Export Model dialog box.
6. Configure Export Settings: The Export Model dialog allows you to adjust various parameters related to the export, such as coordinate system, texture settings, and more. Configure these based on your needs and the requirements of the software you'll be using the model in.
7. Final Export: Once you've configured the settings in the Export Model dialog, confirm your choices to begin the final export process.

Common Export Formats

Reality Capture supports several standard 3D file formats. Choosing the right format depends on where you plan to use the model (e.g., game engine, 3D modeling software, 3D printing). Some common formats include:

Format Extension	Common Use Cases
.obj	Widely compatible, supports mesh and textures
.fbx	Popular for animation and game engines
.stl	Primarily used for 3D printing
.ply	Stores 3D data, often includes color and normal
.dxf	CAD applications, sometimes used for 3D data

Always ensure the format you choose is supported by the software you intend to import the model into.

By following these steps, you can effectively export your detailed 3D models generated within Reality Capture for use in other pipelines.
