Abstract: A facility for specifying a set of graphics commands for performance on behalf of an application is provided. The facility provides a first, command signature data structure specifying a list of resources capable of affecting the outcome of graphics commands among the set. The facility further provides a second, application-defined command buffer data structure that, for each of the graphics commands among a set, represents the graphics command by including a value for each of the resources of the list.

Abstract: Methods, systems, and computer-storage media for efficiently tessellating two dimensional (2-D) curves using a graphics pipeline running on a graphics processing unit (GPU) are provided. A central processing unit (CPU) converts a geometry having one or more 2-D curves into an intermediate tessellation having at least one Bezier fan with a fan origin and four control points. The intermediate tessellation is sent on to the graphics pipeline. A hull shader in the graphics pipeline is configured to approximate the Bezier fan curve by subdividing the curve into a defined number of triangles based on a maximum value of a width or a height of a bounding box containing the four control points of the Bezier fan. A domain shader in the graphics pipeline is configured to determine a vertex position for each of the defined triangles along the curve of the Bezier fan.
