Information Processor, Information Processing Method, and Computer Program Product

According to one embodiment, an information processor is provided with a graphics processing unit (GPU) to display a graphical user interface (GUI) screen on a display module using the GPU. The information processor includes a storage module, a component specifying module, and an instruction converter. The storage module stores node tree information and an association table. The node tree information sets relationship between nodes to be arranged in a virtual three-dimensional (3D) space corresponding to the GUI screen. The relationship includes positional relationship in the virtual 3D space. The association table defines association between each node and a GUI component that constitutes the GUI screen. The component specifying module specifies a GUI component in association with each node referring to the association table. The instruction converter converts the specified GUI component into a GPU drawing instruction referring to the node tree information and outputs the drawing instruction to the GPU.
