According to examples, a processor may place anchor points at determined locations of a digital model of an item to be fabricated by a three-dimensional (3D) fabrication system. The anchor points may include points that remain in place during a placement determination of pores on the digital model and may correspond to locations at which pores are or are not to be formed in the digital model. The processor may determine places at which the pores are to be set in the digital model of the item, in which the pores are to be placed to comply with a predefined constraint with respect to each other and the anchor points and may modify the digital model to place the pores at the determined places in the digital model and to add pores at anchor points that correspond to pores in the digital model.

A projector and a camera are each disposed behind a transparent projection surface. The projector is to rear-project a first image onto the transparent projection surface, whereas the camera is to capture a second image in front of the transparent projection surface. Capture by the camera of the first image as reflected back by the transparent projection surface after rearprojection by the projector, as part of the second image, is minimized.

Image rear-projection and image capture

An example device includes an image capture lens having a first field of view and a viewfinder having a second field of view separate from the first field of view. The image capture lens is to capture an image of a subject in the first field of view. The viewfinder has a first surface that is partially reflective. The first surface is to partially reflect incident light and to partially transmit the incident light therethrough to allow viewing through a second surface of the viewfinder. The second surface is opposite the first surface.
