Abstract: Examples disclosed herein relate to digital mark-up in a three dimensional (3D) environment. An example device for digital mark-up in a 3D environment includes a processor, a display for showing a view of the 3D environment, and a memory including instructions on the processor. When the memory stored instructions are executed on the processor, they cause the processor to generate an anchor point in response to an author input, wherein the anchor point includes a virtual location. When the memory stored instructions are executed on the processor, they cause the processor to generate a mark-up object associated with the anchor point, wherein the mark-up object includes mark-up dimensions, a virtual authoring location, and a selectable association that, in response to being selected, instructs the processor to adjust the view shown in the display to be a view from the virtual authoring location at the time the mark-up object was authored.

Abstract: An example system includes an identification engine to determine production data associated with a three-dimensionally printed object. The system also includes an alignment engine to determine a placement of the three-dimensionally printed object relative to a display device. The system includes a rendering engine to generate an image including a visual representation of the production data. The rendering engine is to position the visual representation of the production data so that representations of data points in the production data will overlay corresponding portions of the three-dimensionally printed object upon displaying by the display device.

Abstract: Methods, systems, apparatus, and computer-readable media (transitory or non-transitory) are described herein for scaling and rendering a virtual hand. According to an example, vision data may be received from a three-dimensional (“3D”) vision sensor. The vision data may capture at least a portion of a user in an environment, and may include data representing the user's hand relative to a touch interaction surface. The vision data may be processed to generate a 3D representation of the user's hand. A scaling center may be identified on the touch interaction surface to scale the 3D representation of the user's hand. The 3D representation of the user's hand may be scaled with respect to the identified scaling center using a scaling factor. The scaling factor may be based on a rendering constraint. A virtual hand may be rendered, e.g., on a display, based on the scaled 3D representation of the user's hand.
