How it works

3D points are created using a form of stereo imaging. Two images from a known camera are required to produce 3D points.

Firstly, a camera needs to be calibrated so that distortions in the image can be accounted for. Images are then taken of the object to be digitised. These images must include known 3D points so that the camera positions and rotations can be calculated. These known points usually take the form of a rig.

Once the camera orientation is calculated for each image, the user can click on a point in one image and click on the same point in another image. These 2D pairs are then used to calculate the 3D point. Points are used to create triangle faces which can have materials and textures assigned to them, like any other 3D editor.
