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: Disclosed are apparatus and methods for rendering using a graphics processing component (GPC). A computing device can receive GPC instructions, with each instruction associated with a portion of a canvas. For each instruction: a first portion of the canvas can be determined and an instruction buffer can be searched to identify a mergeable instruction for the instruction. After identifying the mergeable instruction at a mergeable position within the instruction buffer, one or more instructions in the instruction buffer that include the mergeable instruction can be searched for overlap in the canvas with the first portion. In the event that the one or more instructions do not overlap with the first portion of the canvas, then the instruction can be merged with the mergeable instruction. Each instruction in the instruction buffer can be provided to the GPC for performing the instruction.

Abstract: An operating system may receive transition information indicating that a user-interface of an application is to be transitioned from a first state to a second state. Transition of the user-interface from the first state to the second state comprises a change in a property of a user-interface item. The operating system may, in response to receiving the transition information, obtain from a rendering engine a value for the property of the user-interface item corresponding to the first state. The operating system may embed a module in the rendering engine so as to detect the change in the property of the user-interface item through communication from the application to the rendering engine; and obtain from the module a respective value for the property of the user-interface item corresponding to the second state. The operating system may generate an animation based on a comparison between the value and the respective value.
