PURPOSE:To offer the storage device for executing a display processing at a high speed with regard to a three-dimensional display memory in a three- dimensional graphic display device. CONSTITUTION:This device is constituted so that at the time of generating data from a visual point to be displayed from three-dimensional image data, in order to compare whether a dot to be displayed is the nearest value in the Z axis or not, a Z value of this dot is inputted to a comparing means 2, and the comparing means 2 compares it with a Z value corresponding to its dot stored in a storage means 1, outputs its result, when the Z value of the input data is a near value, and also, the Z value stored by the storage means 1 is updated. |
