1. A video game processing apparatus for controlling progress of a video game while displaying a three-dimensional avatar on a display screen of a display device, the three-dimensional avatar being arranged within a virtual space, the video game processing apparatus comprising: a three-dimensional model generator for generating a three-dimensional partial model on a basis of two-dimensional image data inputted by a user of the video game processing apparatus, the three-dimensional partial model constituting at least a part of a body of a three-dimensional avatar, the part of the body including a face portion of the three-dimensional avatar; a memory for storing a plurality of three-dimensional partial models generated by the three-dimensional model generator; a processor for specifying at least one three-dimensional partial model for each scene in the video game from the plurality of three-dimensional partial models; and the processor for causing the display device to display the three-dimensional avatar in a corresponding scene on the display screen, the three-dimensional avatar including the three-dimensional partial model specified by the processor, wherein the three-dimensional model generator generates each of the plurality of three-dimensional partial models including a three-dimensional face model, the three-dimensional face model being generated by a synthesis of a two-dimensional image of the two-dimensional image data, a drawing of the three-dimensional face model being changed based on at least one operation received from the user.
