Abstract: Examples described herein generally relate to capturing and executing graphics processing operations. A memory trap function can be activated to cause a graphics processing unit (GPU) to report memory accesses in executing graphics processing operations. Based on activating the memory trap function and for each of a sequence of executed graphics processing operations executed by the GPU, a sequence of memory accessing commands and associated portions of memory modified based on executing the sequence of executed graphics processing operations can be received. Each of the sequence of multiple memory accessing commands and associated portions of memory can be stored and provided to the GPU to emulate re-executing of the sequence of executed graphics processing operations by the GPU.

Abstract: Systems and methods for displaying an image of a virtual object in an environment are described. A computing device is used to capture an image of a real environment including a marker. One or more virtual objects which do not exist in the real environment are displayed in the image based at least on the marker.

Abstract: Z-buffer compression may be useful for reducing memory usage bandwidth and for performance optimizations. A trackable method of doing the same may be additionally advantageous, as a lossy z-buffer compression scheme may noticeably alter a displayed object. A z-buffer compression unit receives an uncompressed tile, including a matrix of fragments, each representing a pixel and including a z-value. A minimum and maximum z-values of the tile are determined, and a comparison between each z-value of the tile to the minimum/maximum z-value generates a difference value. Basic tile information is then stored, and a compressed tile is stored in the z-buffer memory if the difference value is below a first threshold, such that each fragment is represented by a difference value and an indicator bit, to indicate if the difference is from the minimum z-value or the maximum z-value. The basic tile information includes the minimum z-value, and the maximum z-value.

Abstract: Systems and methods for computerized drawing of ornamental designs consisting of placed instances of simple shapes. The shapes, called elements, are selected from a small library of templates. The elements are deformed to flow along a direction field interpolated from user-supplied strokes, giving a sense of visual flow to the final composition, and constrained to lie within a container region. In an implementation, a vector field is computed based on user strokes. Streamlines that conform to the vector field are constructed, and an element is placed over each streamline. The shape of the elements may be modified such as by bending, stretching or enlarging to reduce spacing between elements and to minimize variations in spacing to improve aesthetic appearance.
