Abstract

PROBLEM TO BE SOLVED: To easily move an object in parallel on an operating surface by preparing a point to be a reference at the time of parallelly moving an element from a position obtained by an object specifying position obtaining part. SOLUTION: The object specifying position obtaining part 61 selects elements constituting the object so as to specify the object that an operator desires to move in parallel. Then the part 61 selects an element at a minimum distance to a selected position to obtain the position on the selected element. A reference point preparing part 62 calls the part 61 to obtain the selected position and draws a perpendicular from the obtained position to the operating flat surface to prepare a reference point by setting the reference point to be the position crossing the perpendicular and the operating flat surface with each other. An object moving part 63 calls the part 62 to prepare the reference point, locates a position showing a moving destination on the operating flat surface to specify the moving point next and adds a calculated moving distance to the vertexes of the elements constituting the object to move the object in parallel with the operating flat surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD (Comp
The present invention relates to a graphic processing device such as a Uter Aided Design).

[0002]

2. Description of the Related Art When a worker uses a three-dimensional CAD to perform a designing work, a work of translating a created three-dimensional object in parallel to a work plane is frequently required. Conventionally, when performing such work, parallel movement has been realized by the following flow.

First, a reference position of an object to be translated in relation to the work plane is determined. Usually, in this case, the position where the operator picks up the element of the object, the vertex of the object, or the like is used as the reference point. Next, the position to which the reference point is moved is numerically input. At this time, it is necessary to input the movement point such that the distance between the reference point and the work plane and the distance between the movement point and the work plane match so as to be translated in parallel with the work plane. When the moving point is input, by moving the elements that make up the object so that the reference point and the moving point match,
A parallel movement is realized.

[0004]

However, it is often not necessary to strictly determine the moving point for moving the object in parallel with the work plane, and it is troublesome to input the moving point each time the object moves in parallel. Had.

Therefore, it is an object of the present invention to provide a graphic processing device capable of easily translating an object on a work plane.

[0006]

A graphic processing apparatus according to the present invention includes, in a secondary storage device, an object designated position acquisition unit for acquiring a position selected for an element of an object arranged in a three-dimensional space, and an object. A reference point creation unit that creates a reference point when translating an element from the position acquired by the specified position acquisition unit, and an object moving unit that moves to a position where the elements that make up the object are located on the work plane. It has an object parallel moving means.

[0007]

With the above structure, it is not necessary to always input a numerical value in order to determine a moving point, and an object can be easily translated in parallel by locating a point on a work plane.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a device block diagram of a graphic processing device according to an embodiment of the present invention. In FIG.
1 is a central processing unit that processes requested information, 2 is a display device that displays windows, graphic elements, characters, etc., 3 is an input device such as a keyboard, tablet, mouse, etc. for inputting data such as characters, numerical values, and positions, Reference numeral 4 is a main storage device that stores a program that operates on the central processing unit 1 such as an operating system and a window system, and 5 is a secondary storage device that stores the object parallel moving means 6 and the like in the present embodiment.

Next, the object parallel moving means 6 in the present embodiment will be described with reference to the flow charts of FIGS. 2, 3 and 4, and an example in which the present embodiment is also applied is shown in FIGS. 5, 6 and 7. Will be described with reference to. Object parallel moving means 6
Object designation position acquisition unit 61 and reference point creation unit 6 that configure the
2. The object moving unit 63 will be described in order.

The object designated position acquisition unit 61 will be described with reference to the flowchart of FIG. 2 and FIG. In the object designated position acquisition unit 61, first, as shown by a black circle in FIG.
In order to specify an object to be translated, one element that constitutes the object is selected (step 1). Then, the element having the shortest distance to the selected position is selected, and the object designated position acquisition unit 61 acquires the position on the selected element (step 2).

The reference point creating unit 62 will be described with reference to the flowchart of FIG. 3 and FIG. The reference point creation unit 62 first calls the object designated position acquisition unit 61 to acquire the selected position (step 10). A perpendicular line is drawn from the acquired position to the work plane (step 11). A position where the perpendicular and the work plane intersect is created as a reference point (step 12).

For example, in FIG. 6, the selected position is (X,
Since Y, Z) = (a, b, c), the work plane 7 is the XY plane, and Z = 0 on the work plane 7, the reference point is (a, b, 0).

The object moving unit 63 will be described with reference to the flowchart of FIG. 4 and FIG. The object moving unit 63 first calls the reference point creation unit 62 to create a reference point (step 20). Next, the position indicating the movement destination is located on the work plane 7 and the movement point is designated (step 21).

In order to make the reference point and the moving point coincide with each other, the moving distance is calculated for each of the X direction, the Y direction and the Z direction (step 22). The calculated moving distances are added to the vertices of the elements forming the object, and the object is translated in parallel with the work plane 7 (step 23).

For example, as shown in FIG. 7A, when the reference point (a, b, 0) and the moving point (d, e, 0) are set, the moving distance da in the X direction and the moving distance in the Y direction are set. The distance e−b is 0 in the Z direction, and each vertex (X, Y, Z) forming the object is moved to a point (X + (d−a), Y + (e−b), 0) (FIG. 7). (B)).

According to the telephone device of the present invention, the secondary storage device is
An object designated position acquisition unit that acquires a selected position of an element of an object arranged in a three-dimensional space and a point that serves as a reference when translating the element from the position acquired by the object designated position acquisition unit are created. Since the object parallel moving means having the reference point creating section and the object moving section for moving the elements forming the object to the located position on the work plane is provided, the operator can operate the three-dimensional object with a mouse without inputting a numerical value. The parallel movement can be done easily, improving work efficiency.
