An image processing system acquires a first three-dimensional model of an object. The image processing system includes a processor and storage medium encoded with instructions executable by the processor. The instructions include instructions to define a material potential function for a material. The material potential function is a function of a three-dimensional origin point of the material in the object, a three-dimensional propagation limit of the material in the object, and a three-dimensional propagation function of the material in the object. The instructions include instructions to generate a second three-dimensional model of the object based in part on the material potential function and the first model. The second model illustrates propagation of the material through an interior volume of the object at a unit level. A controller generates control signals based on the second model, and a fluid ejection engine performs an additive manufacturing process based on the control signals. Mostrar menos

An example of a computer-readable medium is provided to store machine-readable instructions. The instructions may cause a processor to receive three-dimensional (3D) object representations of an object. The distance between points of a grid applied to 3D object representation and random points on the 3D object representation may provide a sampling error used in calculating a modeling accuracy between the 3D object representations.

In one implementation, a method for generation of a soft-proof file is described. A ticket template and a job definition are associated with input contents. Print-ready data is caused to be generated based on the input content, the job definition, and the ticket template. A soft-proof file is caused to be generated based on the print-ready data, the ticket template, and the job definition.

Examples herein disclose multiple engines to produce output representative of a summary of document produced by each of the multiple engines. The examples apply a weighting mechanism to the output specific to that engine to obtain a value corresponding to that output. The examples identify specialized language if the value corresponding to that output reaches at least a particular threshold.

The instructions may cause the processor to slice the NURBS model to produce slices having the identified slice height and to adaptively subdivide surfaces of the NURBS model whose bounding boxes respectively intersect at least one of the slicing planes until the bounding boxes meet a predefined criterion. In addition, for each of the generated bounding boxes which meet the predefined criterion, the instructions may further cause the processor to determine sample points of the surface with which the bounding box corresponds and to store the sample points of the surfaces for printing.

A technique for displaying a folding document can include connecting an edge of a first to an edge of a second to create a shared edge representing a fold of a folding document. The first and second can form a first area of the folding document, and the first area and a second area of the folding document can be displayed in a graphical interface (GUI).
