A three-dimensional object may be generated. First and second agent distributors may be to respectively selectively deliver a binder agent and a coalescing agent onto portions of a layer of build material. A controller may be to control the first and second agent distributors to respectively selectively deliver the binder agent and the coalescing agent onto respective first and second portions of the layer in patterns derived from data representing a slice of the three-dimensional object to be generated. The first portion having the binder agent may be to bind and solidify into a binder matrix. When energy is applied to the layer the second portion having the second agent may be to coalesce and solidify.

Generating three-dimensional objects

In an example, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to receive an image, a graphical element, and embedding information. The processor further encodes a binary value representing the embedding information into the graphical element. The zeros and ones from the binary value are distinguished in the graphical element by a difference in luminance values applied to segments of the graphical element. The processor further combines the encoded graphical element with the image without altering the image.

Encoding information in a graphical element of an image

Interactive d&#xe9;cor and systems and methods of printing an interactive pattern using an inkjet printer are disclosed. An interactive d&#xe9;cor may comprise a substrate, and an interactive pattern printed on the substrate. The interactive pattern is addressable using a reader device, but is substantially indiscernible to a naked eye at a viewing distance. A decorative image is printed over the interactive pattern. The decorative image is predominant to the naked eye.

Interactive decor

A method includes defining a surface within a first captured image of an environment. The defined surface is identified in a second captured image of the environment. A graphic is overlaid on the surface identified in the second captured image. The second captured image is caused to be displayed to preview the graphic in the environment.
