Abstract:
An optical product can reproduce a first 3D image of at least part of a first 3D object and a second 3D image of at least part of a second 3D object. The optical product comprises a surface configured, when illuminated, to reproduce by reflected or transmitted light, the first 3D image without reproducing the second 3D image at a first angle of view, and the second 3D image without reproducing the first 3D image at a second angle of view. Each portion of first portions can correspond to a point on a surface of the first 3D object, and comprise first non-holographic features configured to produce at least part of the first 3D image. Each portion of second portions can correspond to a point on a surface of the second 3D object, and comprise second non-holographic features configured to produce at least part of the second 3D image.
