发明名称 DISPLAY CONTROL METHOD FOR MOVING IMAGE BASED ON THREE-DIMENSIONAL SHAPE DATA AND NAVIGATION DEVICE
摘要 PROBLEM TO BE SOLVED: To display a moving image based on three-dimensional shape data while ensuring smooth movement as much as possible. SOLUTION: A display method for calculating resource quantity available in rendering, the data quantity of the three-dimensional shape data of one frame and the frame rate of a moving image to render the three-dimensional shape data of one frame within one frame cycle is selected. When such display method is not present, a display method for thinning out frames to execute rendering with the least processing quantity is selected. The display method includes display (b) with a wire frame model where the detail level of expression is low, and the necessary processing quantity of rendering is small and display (a) with a surface model where the detail level of expression is high, and the necessary processing quantity of rendering is large.
