Next, the parts catalog automatic creation system 200 according to the present embodiment will be described.
FIG. 3 shows a block diagram of the parts catalog automatic creation system 200 of this embodiment. The system can automatically generate parts catalog data by receiving the line-of-sight direction specified by the user.

  The data stored as a file in the external storage device as the product data management unit 100 includes data on the part shape, the assembly shape, and the part configuration table of each part constituting the assembly data.

The part shape is a three-dimensional shape model of parts composed of polygon data and color information.
The color information is data specified by red, green, and blue color components and transmittance.
Polygon data is data that represents the surface shape of a part as a set of triangular polygons. One triangular polygon has, as data, three coordinate values defining a triangle and a normal vector value at each point in the three-dimensional coordinate system. Each triangle polygon is assigned (triangle).

By providing the polygon data and the color information to the graphics processing of the computer, an image depicting the shape of the part can be output to a display device such as a display or a file by a known technique.
As the polygon data and color information format constituting the above-described part shape data, various known formats may be used as long as the image of the part shape can be displayed by the graphics processing of the computer.

  The assembly shape is a three-dimensional shape model having, as data, a part shape file name and an arrangement matrix indicating where in the three-dimensional space the part shape is arranged for each part constituting the assembly. .

The arrangement matrix is data of a 4 × 3 affine transformation matrix that translates and rotationally moves coordinate values in a three-dimensional space. When polygon data is acquired from the part shape indicated by the file name, and the coordinate values and normal vector values of each triangular polygon are converted by the placement matrix, the polygon data of the part shape is obtained at the position assembled as an assembly. can get. Here, if the coordinate value before conversion is (x _o , y _o , z _o ), the coordinate value after conversion is (x _t , y _t , z _t ), and the arrangement matrix is M, the conversion is expressed.

However, a _ij (i is any one of 1, 2, 3 and j is any one of 1, 2, 3) is a numerical value that is a rotation component, and a _4j (j is any one of 1, 2, 3). Is a value that becomes a translation component.

By giving the converted polygon data and part color information to the computer's graphics processing for each part that makes up the assembly, an image depicting the shape of the assembly can be created using known techniques in the same manner as the part shape described above. Can be output to a display device such as a display or a file.
The format of the assembly shape data described above is not limited to the determinant described above as long as the image of the part shape can be displayed by computer graphics processing, and various known formats may be used.

The parts configuration table is data in which a part number and a part name of each part constituting the assembly data are associated with a part ID of the assembly shape to form a list.
FIG. 4 shows an example of the data contents of the part configuration table.

  Next, the input unit 201 in the parts catalog automatic creation system 200 according to the present embodiment shown in FIG. 3 will be described.

  The input unit 201 receives the operation of the input device by the user, and passes the input data of the line-of-sight direction (line-of-sight vector) to each processing unit in the parts catalog automatic creation system 200.

  The line-of-sight direction input from the input unit 201 designates from which direction in the three-dimensional space the image in which the three-dimensional shape model is viewed is created. This line-of-sight direction (line-of-sight vector) is specified by a set of polar coordinates α and β as shown in FIG.

  FIG. 6 shows an example of data in the line-of-sight direction. A plurality of line-of-sight direction data can be designated as shown in FIG. 6, and the line-of-sight direction ID is assigned to each polar coordinate in the designated order. In the example of FIG. 6, the units of α and β are shown as radians.

Is stored. Each data is output as a file.

  For the part image, one piece of image data of the part shape is created for each part shape, and orthographically projected images are sequentially created from the line-of-sight direction with the line-of-sight direction ID of 1. A well-known technique may be used to create an orthogonal projection image.

At this time, the display area of the image is a square and is obtained in the next step.
First, the coordinate value of each triangular polygon constituting the polygon data of the part shape is orthogonally projected in the line-of-sight direction. As shown in FIG. 7, the orthogonal projection is based on the coordinates of the line of sight obtained by rotating the coordinate system of the polygon data by using the coordinate values (x, y, z) of the polygon data as polar coordinates α and β given as the line of sight. This is done by converting the coordinate values (i, j, k) of the system.

  This conversion is performed by the following equation.

  The (i, j) coordinate value obtained as a result is the coordinate value on the projection plane (i-j plane).

Next, as shown in FIG. 8, the area occupied by the coordinate values after projection on the projection plane is surrounded by two line segments parallel to the i axis and two line segments parallel to the j axis. Obtained as a rectangle. The rectangle is obtained by extracting the maximum value and minimum value of the i component of each projected coordinate value and the maximum value and minimum value of the j component, i _min , i _max , j _min , and j _max .
A rectangle indicated by an inner solid line in the example of FIG. 8 is an example of the rectangle at this time.

Next, the rectangle thus obtained is coincident with the center, and the smallest square area including this rectangle is obtained as an image display area. This square is determined as the maximum and minimum values of the i component and the maximum and minimum values of the i component, i ' _min , i' _max , j ' _min , j' _max , which are the components of the coordinate values at the four corners. Calculate by the following formula.

The rectangle indicated by the outer broken line in the example of FIG. 8 is an example of a square at this time.
The resolution of the image may be arbitrary, but the image is output at a predetermined resolution such as 480 × 480 pixels.

The assembly image is an image of each part shape calculated from the assembly shape data by the graphics processing of the computer. An image that is orthogonally projected for each line-of-sight direction is created in the same manner as the part image. At this time, the display area of the image is a square, the coordinate values of each triangular polygon constituting the polygon data of each part shape are converted by the arrangement matrix, and the converted coordinate values are obtained in the same steps as the part image.
The resolution of the image may be arbitrary, but the image is output at a predetermined resolution such as 680 × 680 pixels.

  A highlight image (parts-enhanced image) displays a specific part of the parts that make up the assembly data with a prominent color such as red, and the other parts based on a color such as white. Even if it is a part inside the assembly which is displayed in a semi-transparent manner and cannot be seen in the appearance, the image data is such that the assembly position can be understood. Details of this embodiment will be described later.
