Abstract: Examples disclosed herein relate to determining 3D print part placement. In one implementation, a processor generates a user interface to receive user input related to multiple divisions of 3D print parts and a relative ordering between the divisions. The processor may determine part placement information for the parts in the divisions in a 3D print build area based on user input to the user interface. The processor may translate the determined part placement information into 3D printer instructions.

Abstract: Examples relate to a turntable peripheral for three dimensional (3D) scanning. In some examples, 3D scan data of a real-world object is obtained while the object is rotated by the turntable peripheral. Positioning commands are sent to the turntable peripheral to rotate the object. The 3D scan data is collected while the turntable peripheral is in an untilted and/or tilted position.

Abstract: Examples disclosed herein relate to projecting onto a touch-sensitive surface a projection image having projected regions corresponding to target and non-target touch regions. Examples include a computing system having a touch-sensitive surface, and a camera to capture an image representing an object disposed between the camera and the touch-sensitive surface. The computing system may also include a detection engine to identify, based at least on the object represented in the image, at least one touch region of the touch-sensitive surface, and to generate a projection image including a projected region corresponding to the touch region, and a projector to project the projection image onto the touch-sensitive surface.

Abstract: Examples relate to capturing and processing three dimensional (3D) scan data. In some examples, 3D scan data of a real-world object is obtained while the real-world object is repositioned in a number of orientations, where the 3D scan data includes 3D scan passes that are each associated with one of the orientations. A projector is used to project a visual cue related to a position of the real-world object as the real-world object is repositioned at each of the orientations. The 3D scan passes are stitched to generate a 3D model of the real-world object, where a real-time representation of the 3D model is shown on a display as each of the 3D scan passes is incorporated into the 3D model.

Abstract: Examples disclosed herein describe, among other things, a computing system. The computing system may in some examples include a touch-sensitive surface, a display, and at least one camera to capture an image representing an object disposed between the camera and the touch-sensitive surface. The computing system may also include a detection engine to determine, based at least on the image, display coordinates, where the display coordinates may correspond to the object's projection onto the touch-sensitive surface, and the display is not parallel to the touch-sensitive surface. In some examples, the detection engine is also to display an object indicator at the determined display coordinates on the display.

Abstract: A method of implicitly grouping annotations with a document includes with a projection device, projecting an image of a document onto a touch sensitive pad. The method further includes receiving a number of user-input annotations to the document, and with a processor, implicitly associating the annotations with the document without receiving selection of an annotation grouping mode from a user.
