Graphics rendering

A computing device comprising at least one processor, at least one memory device comprising a graphics memory, and a display, the at least one processor configured to:

• traverse a render tree which is indicative of a hierarchy of a plurality of objects, the plurality of objects comprising at least one of an image object and a text object;
• allocate a buffer in the graphics memory;
• and
• generate an image scratchpad by, for each image or text object of the plurality of objects:
• determining an object size and object layout parameters;
• determining a render status of the object;
• and
• responsive to a determination that the render status indicates that image data of the object is in a form which can be directly written to the graphics memory, appending to the image scratchpad by writing the image data of the object to an unoccupied area of the buffer,
• wherein respective image or text objects are rendered to the display by retrieving image data from the image scratchpad, and drawing the retrieved image data based on respective object layout parameters.
