Claim One:
1. A graphics drawing apparatus drawing a graphic, comprising: a memory corresponding to a two-dimensional coordinate system including an X-axis representing a direction in which consecutive memory addresses are arranged and a Y-axis intersecting the X-axis a generation unit, where a sequence of two-dimensional coordinates of vertices is input, generating the coordinates of each of the vertices and virtual vertex coordinates for the coordinates of each of the vertices on the memory, the virtual vertex coordinates being generated by converting the X-coordinate value of the coordinates of each of the vertices to the X-coordinate value of the coordinates of the leading vertex of the sequence; a setting unit setting the coordinates of two vertices of a partial graphic that are to be created as the coordinates of two adjacent vertices, in sequence starting from the leading vertex, and, after setting the coordinates of the trailing vertex of the sequence, setting the coordinates of two vertices of the partial graphic that are to be created as the coordinates of the leading and trailing vertices; and a drawing unit performing a drawing process drawing in the memory a partial graphic defined by the coordinates of two vertices and their virtual vertex coordinates set by the setting unit.
