Leveraging graphics processors to optimize rendering 2-d objects

One or more computer-readable media having computer-executable instructions embodied thereon for performing a method of displaying two-dimensional objects on a display device, the method comprising:

• receiving a plurality of rendering requests from an application, wherein said rendering requests include one or more calls to draw anti-aliased text;
• storing the one or more calls in a staging buffer;
• providing a staging texture, wherein staging operations for anti-aliasing text are executed at the staging texture;
• allocating a rectangular portion of the staging texture to the content of each of the one or more calls;
• drawing the content of each of the one or more calls in a respective rectangular portion of the staging texture, wherein the rectangular portions are aligned in one or more rows along an X direction and the one or more rows are offset in a Y direction by the greatest Y extent of the one or more portions in each row;
• communicating the staging texture to a parallel queue;
• preparing the content of the staging texture in batch by executing one or more staging operations;
• communicating one or more blending calls for each of the one or more calls to an intermediate buffer;
• and
• communicating data stored in the intermediate buffer and the parallel queue to a graphics processing unit via a three-dimensional rendering application program interface (“3-D rendering API”), wherein the content of the parallel queue is processed by rendering said content to a render target and blending said content with one or more graphics generated by processing one or more drawing calls in the intermediate buffer, and thereby displaying said two-dimensional drawing on said display device.

One or more computer-readable media having computer-executable instructions embodied thereon for performing a method of displaying two-dimensional objects on a display device, the method comprising:

• receiving a plurality of rendering requests from an application, wherein said rendering requests include a plurality of drawing calls, one or more state setting calls, and one or more text rendering calls that will be used to draw one or more two-dimensional drawings that include a set of primitive geometries (“geometries”), which is made of relatively more complex geometries and relatively less complex geometries, wherein the relatively more complex geometries are relatively more complex than the relatively less complex geometries;
• coalescing a plurality of drawing calls and state setting calls in an intermediate buffer associated with a render target;
• tessellating the set of primitive geometries into a set of triangles by breaking down at least a portion of the relatively more complex geometries into a sequence of corresponding triangles;
• mapping the sequence of corresponding triangles into a vertex buffer, thereby producing mapped data,
• wherein the sequence of corresponding triangles are mapped to the vertex buffer as vertices, and
• wherein an index is associated with each vertex of said vertices, thereby enabling constant data in a constant buffer to be identified;
• indexing said constant data to derived indexed constant data;
• storing said indexed data in an indexed constant buffer;
• anti-aliasing the content of the plurality of text rendering calls in batch, wherein calls to blend the text are added to the intermediate buffer, and one or more staging textures containing the anti-aliased text are mapped to a parallel queue;
• providing one or more shader assemblies to a three-dimensional rendering application program interface (“3-D rendering API”), thereby generating one or more vertex shaders and one or more pixel shaders;
• and
• communicating a plurality of calls in the intermediate buffer to a graphics processing unit (“GPU”) via the 3-D rendering API, wherein the said plurality of calls are processed using the vertex buffer, constant buffer, parallel queue, and one or more vertex shaders and pixel shaders, thereby rendering the said product of two-dimensional rendering requests at said render target.
