    • PURPOSE:To easily compare an original graphic form and an inputted graphic form with each other, by providing a dot pattern generating device which converts the original form to dot pattern information, a graphic display device, and a facsimile device which inputs position information on the display screen to a controlling processing device. CONSTITUTION:A facsimile device 2 decomposes an original graphic form 1 to dots and sends the dot pattern signal indicating the original graphic form 1 to a reading part 4 for facsimile data of a controlling processing device 3. This reading part 4 data and stores it in a file 5. The dot pattern of this file 5 is converted to a dot pattern for graphic display by a processing part 6 of dot pattern data. The output of the processing part 6 is stored in a file 7, and a dot pattern display control part 8 displayes the same graphic form as a original graphic form 1 on the screen of a graphic display device 12 on a basis of the dot pattern of the file 7. Thus, the original graphic form and an inputted graphic form are compared with each other easily.

    • PURPOSE:To simplify the input operation, by calculated the distance between two prescribed points on an input sheet placed on a digitizer DGT to determine the type of the input sheet and by determining the value of a hit input item on the basis of this type. CONSTITUTION:When the item to be input on an input sheet A is marked with a circle and this sheet is placed on a DGT1 and a sheet type input key is depressed and points Pa and Pb are hit with a stylus pen 2, the distance between points Pa and Pb is calculated in 6, and the result is inputted to a sheet determining part 9. On the basis of this result, the determining part 9 determins a type of the sheet and reads out a table record of this input sheet to an item value determining part 12 from a sheet-classified table fine 11. The position and the inclination of the origin Pa of the sheet are obtained in an origin position determining part 7 and a sheet inclination calculating part 8, respectively, and these values are inputted to an item hit position determining part 10. Next, when the item marked with a circle on the sheet is hit with the pen 2, its coordinates are inputted to the determining part 10 through a register 5, and the output of the determining part 10 is inputted to the determining part 12, thus determining the value of the item.

    • PURPOSE: To shorten significantly the processing time with less data volume and to prevent plural solutions by utilizing a picture producing and converting means which reads out data stored in a storage means, and produces and converts a picture.
      CONSTITUTION: Data for showing a plane on a plane where the surface of a wire frame is set, for instance, data provided with cores, that is, graphic elements of a dot, is stored in a picture information addition data memory pat 13, and said data is converted in a picture production/conversion pat 14 based on the data for showing the position and direction of a surface so as to produce surface data. The surface data transmitted to a surface model data memory part 5 is produced to a stereoscopic perspective in a perspective conversion part 6, and a hidden outline is removed by a hidden outline processing part 7 to output it to an output part 8.

    • PROBLEM TO BE SOLVED: To enable seamless switching between two point perspective projection and three point perspective projection. SOLUTION: Line of sight vectors V1 and V2 showing a direction of looking into a virtual three-dimensional space 1 from a viewpoint 3 are decided (step S2) in response to an operation input (step S1). When the directions of the vectors V1 and V2 are close to a horizontal direction, two point perspective projection is adopted, and as the inclination of the vectors V1 and V2 with respect to the horizontal direction become larger, a projection condition on which the influence of three point perspective projection upon two point perspective projection is increased is decided (step S3). A three-dimensional model 2 is subjected to perspective projection according to the decided projection condition to generate an image (step S4). The generated image is displayed (step S5).
    • 要解决的问题:实现两点透视投影和三点透视投影之间的无缝切换。 解决方案:响应于操作输入,决定从视点3观察虚拟三维空间1的方向的视线矢量V1和V2(步骤S2)(步骤S1)。 当向量V1和V2的方向接近水平方向时,采用两点透视投影,并且随着矢量V1和V2相对于水平方向的倾斜度变大,投影条件 决定两点透视投影的三点透视投影(步骤S3)。 根据决定的投影条件对三维模型2进行透视投影以生成图像(步骤S4)。 显示生成的图像(步骤S5)。
