Techniques for ink anchoring are described. In one or more implementations, an interactive canvas is displayed on one or more display devices of a computing device. An ink object is generated by digitizing ink input received to the interactive canvas. In response to determining that the ink object overlaps an object in the interactive canvas, the ink object is anchored to the object such that a spatial relationship between the ink object and the object is maintained if the ink object or the object is manipulated.

Ink Anchoring

A method for operating a computing system is provided. The method includes at a local computing device and while an ink input is occurring, rendering a local uncommitted ink stroke on a local display based on the ink input and sending uncommitted ink data corresponding to the uncommitted ink stroke to a remote computing device, the uncommitted ink data including an uncommitted ink stroke path and a global unique identifier differentiating the uncommitted ink data from other uncommitted ink data corresponding to different computing devices and ink inputs. The method further includes responsive to receiving an ink stroke commitment input, rendering a local committed ink stroke on the local display and sending committed ink data including an ink commitment command and the global unique identifier associated with the uncommitted ink stroke path to the remote computing device.

Synchronizing digital ink stroke rendering

Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.

Leveraging graphics processors to optimize rendering 2-D objects

Systems and methods are disclosed for providing texture tiling. The disclosed systems and methods may include copying a source image into a texture of a size the same or larger than the source image. Furthermore, the disclosed systems and methods may include displacing texture coordinates corresponding to the texture into a desired range. A displacement map may be used in displacing the texture coordinates. Moreover, the disclosed systems and methods may include rendering, within the desired range, an output image corresponding to the texture coordinates associated with the texture.

Methods and systems for providing texture tiling and mirroring

Aspects of the subject matter described herein relate to applying effects to a target via compositing rendering layers. In aspects, an intent is determined and a area of a target copied to a surface based on the intent. Then, rendering may continue to the target without changing to another target. Later, the surface is composited back to the target to apply an effect to the target.
