However, using additional information (multiple data, motion vectors, prior), one can infer a more accurate object location with a sub-pixel resolution, i.e. With an accuracy finer than that of the pixel width, at a fraction of the pixel size, with non-integer coordinates. Chrome OS’s shelf is just like the macOS Dock. To add apps to the shelf, simply right-click on an icon and select Pin to shelf. You can do the same to remove an app (Unpin) or you can drag. PixelStyle Photo Editor for Mac is an all-in-one photo editing and graphic design software, providing professional high-quality photo processing tools to edit the photos, enhance and touch up photos on Mac OS X; PixelStyle Photo Editor comes with a huge range of high-end filters including lighting, blurs, distortions, tilt-shift, shadows, glows and many more. The plugin displays the pixel values of a square neighborhood around the current cursor position as a table. The position can be fixed by a keystroke; in this case the last cursor position is used further on and marked in the image. The arrow keys nudge this position if the Pixel Inspector window is in the foreground.
ActorPositionWS
ActorPositionWS outputs Vector3 (RGB) data representing the location of the object with this material on it in world-space.
In this example, you can see that ActorPositionWS is being fed directly into the Base Color of the material. As a result, each of the spheres with the material applied to them show a different color as they are moved to different locations in 3D space. Note that the result of the ActorPositionWS node is being divided by 1600 to create a nice blend-in color, rather than a pop.
CameraPositionWS
The CameraWorldPosition expression outputs a three-channel vector value representing the camera's position in world space.
The preview sphere changes color as the camera rotates.
LightmapUVs
The LightmapUVs expression outputs the lightmap UV texture coordinates in the form of a two-channel vector value. If lightmap UVs are unavailable, it will output a two-channel vector value of (0,0).
ObjectOrientation
The ObjectOrientation expression outputs the world-space up vector of the object. In other words, the object's local positive z-axis is pointing in this direction.
ObjectPositionWS
The ObjectPositionWS expression outputs the world-space center position of the object's bounds. For example, this is useful for creating spherical lighting for foliage.
ObjectRadius
The Object Radius outputs a value equal to the radius of a given object in Unreal units. Scaling is taken into account and the results can be unique for each individual object.
In this example, both meshes are receiving this material in which the ObjectRadius is fed into Diffuse. The ObjectRadius output is being divided by 512 to provide a more meaningful visual result.
Panner
The Panner expression outputs UV texture coordinates that can be used to create panning, or moving, textures.

Panner generates UVs that change according to the Time input. The Coordinate input can be used to manipulate (e.g. offset) the UVs generated by the Panner node. ParticlePositionWSThe ParticlePositionWS expression outputs Vector3 (RGB) data representing each individual particle's position in world space. In this image, ParticlePositionWS is being fed into emissive color to visualize the data. The particle system has been scaled up to show how the color is changing based on position. PixelNormalWSThe PixelNormalWS expression outputs vector data representing the direction that pixels are facing based on the current normal. In this example, PixelNormalWS is fed into Base Color. Notice how the normal map is used to give the per-pixel result. RotatorThe Rotator expression outputs UV texture coordinates in the form of a two-channel vector value that can be used to create rotating textures.
