Abstract: Disclosed are apparatus and methods for rendering using a graphics processing component (GPC). A computing device can receive instructions for a GPC, including an instruction IA associated with a first portion of a canvas. An insertion position in an instruction buffer for instruction IA can be determined by: determining an instruction IB in the instruction buffer that is associated with a second portion of the canvas. If the first and second portions overlap, the insertion position can be based on an overlapping-instruction position of IB in the instruction buffer. Otherwise, if instructions IA and IB are similar, then the insertion position can be based on a second position of IB in the instruction buffer. Otherwise, the insertion position can be determined based on an ending position of the instruction buffer. Instruction IA can be inserted in the instruction buffer at the insertion position.

Abstract: Disclosed are apparatus and methods for tessellating shapes. A computing device that has a display can receive an instruction to draw a shape. The computing device can determine a scale factor for the shape. The computing device can determine a set of polygons that tessellate the shape based on the scale factor. The set of polygons can include at least two polygons. The computing device can display the polygons in the determined set on the display.

Abstract: An electronic device (102) includes a display (104) to display a layout (108) of views, a user input component (212, 214, 216) to receive input representative of a positioned event (118), and a positioned event handler component (226) to detect the positioned event. The electronic device further includes a registry management component (230) to identify a terminal view (122) of the layout of views based on a location of the positioned event and a view tree management component (228) to construct an ancestor chain (126) of one or more ancestor views of the terminal view from the layout. The positioned event handler component is to sequentially dispatch the positioned event in the ancestor chain starting at a root view (110) of the ancestor chain.

Abstract: Methods and apparatus are provided for displaying shadows of circular light sources. A computing device can determine a light source and an occluding polygon that is between the light source and a receiver surface, where the occluding polygon includes vertices connected by edges. The computing device can determine a shadow of the occluding polygon on the receiver surface by at least: determining, for a particular vertex, a projection vertex on the receiver surface by projecting a ray from the center point through the particular vertex; determining an outline polygon based on the projection vertex; determining a projection circle around the projection vertex; determining a penumbra of the shadow based on exterior tangents outside of the outline polygon; and determining an umbra of the shadow based on interior tangents inside the outline polygon. The computing device can display at least part of the shadow.
