simple-capture-sample.cpp

This basic example shows you how to start using a 3D scanner in the SDK.

The code below includes all the necessary steps to initialize a device, capture a single frame and store the resulting 3D surface to an OBJ file on the disk.

Note

If you need a comprehensive sample with efficient multithreading and frame registration, consider using scanning-and-process-sample.cpp.

The files required for compiling this sample are packed in the archive.
