Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material design method for designing a design of a building material using a computer.
The present invention relates to a building material design method for designing a design of a block building material in which a plurality of pieces having an uneven pattern on an outer surface are arranged.

[0002]

2. Description of the Related Art The design of exterior building materials or interior building materials is usually designed in blocks of a predetermined size in which a plurality of pieces each having an uneven surface pattern and various shapes are arranged.

[0003] In designing such a design of a building material,
Conventionally, a real stone pattern is transferred to a gypsum block on the basis of a two-dimensional CG created by a designer, each piece is created, and a plurality of pieces are arranged. In addition, a method was also used in which a designer directly carved an uneven pattern on a gypsum block. However, since such a method is manually performed, there are problems in quality, delivery time, and cost.

As a method for solving the above problem, a method using a CAD system has been proposed. For example, Japanese Unexamined Patent Publication No. HEI 8-18086 discloses that a height image is created by three-dimensionally measuring an object having an uneven surface, and a desired part is cut out from the height image to be used as a partial element, which is attached to a design area to design a building material. And a technique for generating data for processing from the design data has been proposed. In addition, Japanese Patent Application Laid-Open
Japanese Patent Application Laid-Open No. -69121 discloses that a building material sample having irregularities on its surface is three-dimensionally measured, height data is created, pieces are cut out, enlarged and reduced, etc., and then laid out at a predetermined position. Has been proposed.

[0005] However, in the case of using the CAD system described above, since the three-dimensional irregular pattern data obtained by three-dimensionally measuring an object having an irregular pattern on the surface is simply modified and then laid out, the entire building material is laid out. It was not easy and it took time to bring the layout and the relief pattern closer to what the designer designed.

In particular, recently, there is an increasing need for irregularities and joint groove patterns on the surface of building materials having very complicated and diverse designs, and moreover, there is a demand for faster supply. The method had its limitations.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a building material designing method capable of easily and quickly designing building materials of complicated and various designs without requiring complicated work.

The method includes a second step of designing an array of a plurality of pieces using the AD system. Thus, two types of C
Using the AD system, building materials of various designs,
It is possible to design quickly and accurately without using a high-speed and large-capacity computer.

In the building material designing method according to the present invention, the second step includes selecting and arranging the pieces designed in the first step.

The first step in the building material designing method of the present invention is executed for each of the arranged pieces after the arrangement design of each piece in the second step.

[0011] The building material design method of the present invention further includes a step of displaying a color-coded image based on the thickness direction data of the shape data of the block. This makes it possible to easily and accurately evaluate the design of the designed building material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is a diagram showing a schematic flow of a designing method according to a first embodiment of the present invention. In step 1 (S1), the designer creates an image of the entire building material block. By this image production, the outlines of the shapes and the concavo-convex patterns of the plurality of pieces and their layouts are presented. For the presentation, an image image may be created by a computer using a two-dimensional CAD system, an illustration system, or the like, or may be actually drawn on paper.

In step 2 (S2), an uneven pattern of the image produced in step 1 is obtained from a natural stone or the like. The uneven pattern data is managed as, for example, data obtained by converting three-dimensional point sequence data acquired by a three-dimensional measuring device using an imaging device into three-dimensional polygon data (polygon data can be created by the three-dimensional measuring device). Is done. This conversion is performed using a second three-dimensional CAD system that handles polygon data. At this time, the depth of the unevenness is also adjusted. As a three-dimensional CAD system that handles polygon data, for example, Rapid Form (INUS Tec)
hnology).

Next, in step 3 (S3), a building material block is designed. First, in step 31 (S31), a first three-dimensional CAD system that handles a plurality of pieces of the produced image and processes voxel data is used. Design using In designing each piece, the three-dimensional polygon data obtained in step 2 is converted into voxel data, and then the shape and details of the uneven pattern are corrected. It is preferable that the uneven pattern of the inclined portion of each piece is performed by a Boolean operation of a plurality of uneven pattern data. 3D C that handles voxel data
Since the AD system handles a large amount of data, it is preferable to design the AD system in pieces. It is also possible to design a plurality of pieces collectively according to the capability of the computer. As a three-dimensional CAD system that handles voxel data, for example, Free Form (Sensable tec)
hnologies) can be used.

When the design of a plurality of required pieces is completed in step 31, the layout of each piece is designed in accordance with the image produced in step 1 in step 32 (S32). The layout design is performed using the polygon data converted from the voxel data obtained in step 31 and using a second three-dimensional CAD system that handles polygon data. The layout preferably places each piece on a natural jointed base. The base with natural joints is obtained in advance by the method of step 2.

It is preferable that the conversion of the three-dimensional point sequence data into the three-dimensional polygon data be performed via an STL intermediate data format. In designing a piece, a method of transferring photographic data of a material having various concavo-convex patterns and making it three-dimensional can be adopted.

FIG. 2 is a diagram schematically showing data used in step 3 of FIG. Each piece P1, P2,

It is the figure which arranged the piece designed using. In FIG. 3, Q1, Q2, Q3, Q4,... Are obtained by converting the voxel data of each piece designed in step 31 into polygon data and arranging them on the base B. In FIG. Is shown.

The design data of the building material block in step 3 is subjected to a rendering process in step 4 and displayed, and the overall arrangement, uneven pattern, and the like are evaluated (step 5).
(S5)). When displaying, it is preferable to display an image that is color-coded based on the thickness direction data of the building material block. As a result of the evaluation, if the design needs to be modified, the process returns to step 3 again to change the design.

If the evaluation in step 5 is OK, the CAD
Based on the three-dimensional shape data created by the system, NC machining data for manufacturing a mold is created (step 6).
(S6)). In addition, the design of these building material blocks,
The rendering and processing data creation processing is performed using a keyboard,
The processing is executed using one or a plurality of computers having a display device for displaying operation means such as a mouse and a building material design.

(Second Embodiment) FIG. 4 is a diagram showing a schematic flow of a design method according to a second embodiment of the present invention. The difference from the flow of FIG. 1 is that the designer creates an image of the entire building material block 10 (S10).
And step 30 for designing a building material block (S30)
It is. Steps other than Step 10 and Step 30 are the same as those in FIG.

Step 10 is different from step 1 in that
When presenting the outlines of the shapes and the concavo-convex patterns of a plurality of pieces and their layouts, the layout is expressed in two-dimensional C
The point is that the data is output as electronic data using an AD system, an illustration system, or the like. FIG. 5 schematically shows an example.

Step 30 comprises a layout three-dimensionalizing step of step 33 and a piece concave / convex pattern designing step of step 34. Step 33 is for converting two-dimensional data as shown in FIG. 5 into three-dimensional data, and is performed using a three-dimensional CAD system that handles polygon data. Next, in step 34, a Boolean operation of the concavo-convex pattern data is performed on each piece to obtain a piece with a detailed concavo-convex pattern. Step 34 is a three-dimensional C processing for voxel data.
This is performed using an AD system. Further, it is preferable that the data conversion be performed via the STL intermediate data format as in the first embodiment. As for the piece design, as in the first embodiment, a method of transferring photographic data of a material having various concavo-convex patterns and making it three-dimensional can be adopted.
