PURPOSE:To set apparent texture patterns to be constant without depending on the inclination of a vector. CONSTITUTION:When the texture patterns are plotted at corresponding inclination angles, texture patterns which apparently become the same texture patterns are stored in texture pattern memories 12-1 to 12-n corresponding to respective inclination angles as data. The respective texture pattern memories 12-1 to 12-n are referred to by addresses obtained by counting a dot clock by a counter 10, and enable signals obtained as data as a result are inputted to n 1 selector 14. The n 1 selector 14 inputs angle information showing the inclination angle of the vector from an SEL terminal and selects one enable signal. Since the enable signal is that showing the texture pattern deformed in accordance with the inclination angle of the vector, it is prevented that the apparent texture pattern changes in accordance with the inclination angle of the vector. |
