In order to determine the width of each dart so that the width of the dart increases as the distance between the clothes and the human body model at the position where each dart is formed increases, and the width of the dart increases as the difference in the circumference increases. Width determination means;
To determine the length of each dart so that the dart is extended along the axial direction of the human body model, and the end point of the dart is the point where the distance between the clothes and the human body model is less than or equal to the predetermined value on the extension line of the dart Length determination means,
The dart having the design unit has a width determined by the width determination unit at the position generated by the generation unit and functions as a unit for designing the dart on the clothes so that the end point is the point determined by the length determination unit. In the design program.
　この発明では、例えばダーツの形成位置をオペレータが入力すると、自動的にダーツの形成位置での衣服と人体モデルとの距離を求める。また衣服の周長と人体モデルの周長との差を求め、ダーツの形成位置から人体モデルまでの距離に応じて、周長の差を各ダーツに分配し、ダーツの幅とする。そして衣服が人体モデルとほぼ接触する点、即ち衣服と人体モデルとの距離が所定値以下となる点、までダーツを延長し、ダーツの終点とする。従って、ダーツの幅と長さを自動的にデザインできる。ダーツの幅は衣服が人体モデルに自然に接するように定められ、ダーツの長さは衣服が自然に人体モデルに接する点で終わるように定められる。従って衣服が人体にフィットするように、ダーツをデザインできる。 In this invention, for example, when an operator inputs a dart formation position, the distance between the clothes and the human body model at the dart formation position is automatically obtained. In addition, the difference between the circumference of the clothes and the circumference of the human body model is obtained, and the difference in circumference is distributed to each dart according to the distance from the position where the dart is formed to the human body model, and used as the width of the dart. Then, the dart is extended to a point where the clothes are almost in contact with the human body model, that is, a point where the distance between the clothes and the human body model is equal to or less than a predetermined value, and is set as the end point of the dart. Therefore, the width and length of the dart can be designed automatically. The width of the dart is determined so that the clothes naturally touch the human body model, and the length of the dart is determined so that it ends at the point where the clothes naturally touch the human body model. Therefore, the dart can be designed so that the clothes fit the human body.
　この明細書において、デザイン方法に関する記載はそのままデザイン装置やデザインプログラムにも当てはまり、デザイン装置に関する記載はそのままデザイン方法やデザインプログラムにも当てはまる。衣服は布帛からなるものでも、編地等からなるものでも良い。
　ダーツの形成位置は例えばマニュアルで指定するが、ダーツの個数を指定すると、データベース等に記憶させた経験則に基づき、ダーツの形成位置を自動的に決定するようにしても良い。 In this specification, the description regarding the design method also applies to the design apparatus and the design program as it is, and the description regarding the design apparatus also applies to the design method and the program as it is. The clothes may be made of fabric or knitted fabric.
The dart formation position is specified manually, for example, but when the number of darts is specified, the dart formation position may be automatically determined based on an empirical rule stored in a database or the like.
　衣服を人体が着装するには、ある程度のゆとり、即ち隙間が必要である。そこで衣服と人体モデルとの距離を取り扱う際に、両者の距離を計算し、計算した距離から所要の隙間を引いても良い。この場合、距離が０で衣服は人体モデルに密着する。しかし衣服と人体モデルとの計算上の距離から予め所要の隙間を引いたものを、距離としても良い。この場合、距離が０で、衣服と人体モデルとの間には適切な隙間がある。このことは衣服と人体モデルとの周長の差の算出でも同様で、周長の差を求めた後に所要のゆとりを引いても良く、この場合、周長の差が０で、衣服は人体モデルに密着する。あるいはまた、予め所要のゆとりを持たせるように周長の差を求めても良く、この場合、周長の差が０で衣服と人体モデルとの間に適切な隙間がある。 A certain amount of clearance, that is, a gap, is necessary for the human body to wear clothes. Therefore, when handling the distance between the clothes and the human body model, the distance between the two may be calculated, and a necessary gap may be subtracted from the calculated distance. In this case, the distance is 0 and the clothes are in close contact with the human body model. However, the distance obtained by subtracting a necessary gap in advance from the calculated distance between the clothes and the human body model may be used. In this case, the distance is 0, and there is an appropriate gap between the clothes and the human body model. This also applies to the calculation of the difference in circumference between the clothing and the human body model. After obtaining the difference in circumference, the required clearance may be subtracted. In this case, the difference in circumference is 0, and the clothing is the human body. Close contact with the model. Alternatively, the difference in circumference may be obtained in advance so as to have a required clearance. In this case, the difference in circumference is 0 and there is an appropriate gap between the clothing and the human body model.
　好ましくは、長さ決定ステップでは、ダーツの延長線上の複数の位置で衣服と人体モデルとの距離を求め、求めた距離が大きいほどダーツの幅が大きくなるように、前記延長線に沿った各ダーツの幅を決定する。
　このようにすると、人体モデルと衣服との距離が直線的に減少する場合、直線的なダーツとなる。そして人体モデルと衣服との距離が直線的でなく変化する場合、曲線的なダーツとなる。ダーツの各部で、ダーツの幅が人体モデルとの距離に応じて変化するので、より人体にフィットするダーツが得られる。 Preferably, in the length determining step, the distance between the clothes and the human body model is obtained at a plurality of positions on the extension line of the dart, and the width of the dart is increased as the obtained distance is increased. Determine the width of the dart.
If it does in this way, when the distance of a human body model and clothes decreases linearly, it will become a linear dart. When the distance between the human body model and clothes changes instead of being linear, it becomes a curved dart. In each part of the dart, since the width of the dart changes according to the distance from the human body model, a dart that fits the human body can be obtained.
　また好ましくは、衣服の左右半身に対して、ダーツの形成位置とダーツの幅とダーツの長さとを決定し、得られたダーツの形成位置と幅と長さを衣服の左右他の半身に左右対称にコピーする。
　実際の人体は左右がほぼ対象なので、左右の半身に対してダーツをデザインし、他の半身に左右対称にコピーすると、ダーツのデザインでのデータ処理量を約１／２にできる。また左右各々に対してダーツを最初からデザインすると、例えばダーツの形成位置や幅、あるいは長さが左右で対称でないことが生じる。ダーツの形成位置が左右で対称でないのは、多くの場合、ダーツの形成位置が不適切に入力されたからである。また幅や長さが左右で対称でないのは、着装状態のシミュレーションで、衣服が左右対称に着装されず、このため衣服と人体モデルとの距離が左右で非対称なためである場合が多い。そこで左右の半身に対するダーツのデザインを他の半身にコピーすることは、デザイン上もかえって良い結果を生むことが多い。　　 Preferably, the dart formation position, the dart width and the dart length are determined for the left and right half of the garment, and the dart formation position, width and length obtained are determined by the left and right other garments. Copy symmetrically.
Since the actual human body is almost right and left, designing darts for the left and right halves and copying them symmetrically to the other halves can reduce the amount of data processing in the dart design to about 1/2. Further, if the darts are designed from the beginning for each of the left and right, for example, the formation position, width, or length of the darts may not be symmetrical on the left and right. The reason why the dart formation position is not symmetrical on the left and right is that the dart formation position is input improperly in many cases. Also, the reason why the width and length are not symmetrical left and right is often because the clothing is not worn symmetrically in the simulation of the wearing state, and therefore the distance between the clothing and the human body model is asymmetrical in the left and right. Therefore, copying dart designs for the left and right halves to the other halves often yields good results.

　以下に本発明を実施するための最適実施例を示す。 The following is an optimum embodiment for carrying out the present invention.
　図１～図１３に、実施例での、ダーツを有する衣服のデザインを示す。デザイン装置２はコンピュータシステムから成り、４はバス、６はカラーモニタ、８はマウス、１０はキーボード、１２はカラープリンタである。マウス８に代えて、トラックボールやジョイスティック、スタイラスなどを用いてもよい。１４はＬＡＮインターフェースで、１６はＣＤ－ＲＯＭやＵＳＢメモリなどのリムーバブルメモリであり、１８はスキャナで、デザイン画像の読み込みなどを行う。 1 to 13 show designs of clothes with darts in the embodiment. The design apparatus 2 comprises a computer system, 4 is a bus, 6 is a color monitor, 8 is a mouse, 10 is a keyboard, and 12 is a color printer. Instead of the mouse 8, a trackball, a joystick, a stylus, or the like may be used. 14 is a LAN interface, 16 is a removable memory such as a CD-ROM or USB memory, and 18 is a scanner for reading design images.
　２０は汎用のメモリで、画像以外のデータやプログラム、ファイルなどを記憶し、２２は画像メモリで、画像データを記憶する。デザイン装置２は図示しないＣＰＵやグラフィックユニットなどを備え、これらとメモリ２０、画像メモリ２２、及びメモリ２０に記憶したデザインプログラムにより、パーツ接合部２４～デザイン編集部３９を実現する。 20 is a general-purpose memory for storing data, programs, files, etc. other than images, and 22 is an image memory for storing image data. The design apparatus 2 includes a CPU, a graphic unit, and the like (not shown), and realizes the part joining portion 24 to the design editing portion 39 by using these, the memory 20, the image memory 22, and the design program stored in the memory 20.
　パーツ接合部２４は、衣服の袖、襟、前身頃、後身頃、ポケット、袖口などの各パーツを接合し、衣服の形状とすると共に、衣服のパターンデータを記憶する。３Ｄシミュレータ２６は、人体モデル記憶部３０に記憶した人体モデルに対し、パーツ接合部２４で生成した仮想的な衣服を着装させ、着装結果を３次元的にシミュレーションする。この結果、仮想的な衣服を人体モデルが着装した状態を表す、３次元データが得られる。位置合わせ部２８は衣服の中心（図４のＢ点）と人体モデルの中心（図４のＡ点）を左右方向に関して位置合わせする。人体モデル記憶部３０は人体モデルの３次元データを記憶し、人体モデルは個々の人に対応しない一般的なモデルでも、人体形状の実測値に基づくものでもよい。 The parts joint section 24 joins parts such as a sleeve, a collar, a front body, a back body, a pocket, and a cuff of the clothes to form a shape of the clothes and stores pattern data of the clothes. The 3D simulator 26 puts on the human body model stored in the human body model storage unit 30 with the virtual clothes generated by the part joint unit 24 and simulates the wearing result three-dimensionally. As a result, three-dimensional data representing the state in which the human body model is wearing virtual clothes is obtained. The alignment unit 28 aligns the center of the clothes (point B in FIG. 4) and the center of the human body model (point A in FIG. 4) in the left-right direction. The human body model storage unit 30 stores three-dimensional data of the human body model. The human body model may be a general model that does not correspond to an individual person or may be based on an actual measurement value of the human body shape.
　ダーツ配置部３２は衣服に対してダーツを配置する。ダーツは例えば１つの水平面内に複数配置され、例えばウェストの周囲などに配置する。隙間処理部３４は、ダーツを配置する線に沿って、パターンデータから衣服の周長を求め、人体モデルの周長との差を求める。衣服が厚さを持っている場合、衣服の内側の周長を求める。人体モデルが衣服を着装するためには、ある程度のゆとりが必要である。ゆとりに対応するパラメータとしてゆとりｄ，ｆを考え、ｄは周長でのゆとりで、ｆは衣服の内面から人体モデルの表面までの距離のゆとりである。そして隙間処理部３４では、衣服と人体モデルの周長の差Ｓからゆとりｄを引いたもの（Ｓ－ｄ）を、各ダーツに分配する。なお衣服では、前身頃と後身頃との間などの縫合部でもダーツと同様の重ね縫いを行い、これは通常ダーツとは呼ばないが、処理の内容がダーツと同じなので、この明細書ではダーツに含める。前身頃と後身頃の縫合部は位置を指定する必要がない。隙間処理部３４は、３Ｄシミュレーション結果から、衣服の内面と人体モデルとの距離を求め、この距離に比例するように、周長の差Ｓからゆとりｄを引いたものを各ダーツに分配し、分配された値がダーツの幅となる。 The dart placement unit 32 places darts on clothes. A plurality of darts are arranged, for example, in one horizontal plane, for example, around the waist. The gap processing unit 34 obtains the circumference of the clothing from the pattern data along the line where the dart is arranged, and obtains the difference from the circumference of the human body model. If the garment has a thickness, find the perimeter inside the garment. In order for the human body model to wear clothes, a certain amount of clearance is required. Considering the clearances d and f as parameters corresponding to the clearance, d is the clearance in the circumference, and f is the clearance of the distance from the inner surface of the clothing to the surface of the human body model. Then, the clearance processing unit 34 distributes the difference (S−d) obtained by subtracting the clearance d from the circumference difference S between the clothes and the human body model to each dart. In clothing, the same stitching as darts is performed at the stitching part between the front body and back body. This is not usually called darts, but the content of the process is the same as darts. Include in It is not necessary to specify the positions of the stitched portions of the front body and the back body. The gap processing unit 34 obtains the distance between the inner surface of the clothes and the human body model from the 3D simulation result, and distributes the difference of the circumference S minus the clearance d to each dart so as to be proportional to the distance. The distributed value is the width of the dart.
　隙間処理部３４はさらに、人体モデルの軸方向に沿って、即ちスカートなどの場合であればウェストからヒップの方向に向かって、またブラウスやジャケットなどの場合であればウェストから胸囲及びヒップの方向に向かって、即ち上下双方にダーツを延長する。そして延長線上の複数の点で、衣服と人体モデルとの距離に応じてダーツの幅を決定する。例えば、ウェストの位置で求めたダーツの幅を、延長線上での人体モデルと衣服との距離に比例して変化させる。この時、ダーツの延長線上では、周長の差を求めなくても良い。あるいはダーツの延長線上の各点で、衣服と人体モデルとの周長の差と、人体モデルと衣服との距離とを求めて、周長の差を各ダーツに分配しても良い。隙間処理部３４はさらに、ダーツの延長線上で衣服と人体モデルとの間隔を測定し、間隔がゆとりｆ以下になると、ダーツの終点とする。ｆは例えば各ダーツに対して共通の定数である。 The gap processing unit 34 further extends along the axial direction of the human body model, that is, from the waist to the hip in the case of a skirt, and from the waist to the chest and hip in the case of a blouse or a jacket. Extend the dart towards the top, ie both up and down. Then, at a plurality of points on the extension line, the width of the dart is determined according to the distance between the clothes and the human body model. For example, the width of the dart obtained at the waist position is changed in proportion to the distance between the human body model and the clothes on the extension line. At this time, it is not necessary to obtain the difference in circumference on the extension line of the dart. Alternatively, the difference in circumference between the clothes and the human body model and the distance between the human body model and clothes may be obtained at each point on the extension line of the dart, and the difference in circumference may be distributed to each dart. Further, the gap processing unit 34 measures the distance between the clothes and the human body model on the extension line of the dart, and sets the end point of the dart when the distance is less than f. For example, f is a constant common to each dart.
　ダーツ形状作成部３６は、ダーツ配置部３２で求めたダーツの起点と、隙間処理部３４で求めたダーツの幅及びダーツの終点を用いて、ダーツの形状を決定する。このようにして、二等辺三角形状あるいは曲線状のダーツ形状を決定する。ダーツの配置、隙間の処理（ダーツの幅と長さ）、及びダーツ形状は、衣服の左右半身に対して処理すれば良く、コピー部３８でこれらのデータを衣服の他の半身に対し左右対称にコピーする。以上のようにして、ダーツのデザインが決定されると、デザイン編集部３９で衣服のデザインデータを変更し、デザインデータにダーツを追加する。 The dart shape creation unit 36 determines the shape of the dart using the dart starting point obtained by the dart placement unit 32, the dart width and the dart end point obtained by the gap processing unit 34. In this way, an isosceles triangular or curved dart shape is determined. The arrangement of darts, clearance processing (dart width and length), and dart shape need only be processed on the left and right half of the garment, and the copy unit 38 symmetrically stores these data with respect to the other half of the garment. Copy to. When the dart design is determined as described above, the design editing unit 39 changes the design data of the clothes and adds the dart to the design data.
　図２～図７により、ダーツのデザインを説明する。衣服をデザインし、３次元的に人体モデルへの着装状態をシミュレーションする。例えば図３の４０は衣服のパターンであり、ここにパターンはパターンデータないしはパターンペーパーの意味で、データ処理上はパターンデータの意味である。４２は人体モデルである。図３Ａ)は着装状態を側面視で示し、Ｂ)は正面視で示している。また●でダーツの位置（基点）を示す。この位置から図の矢印方向にダーツを延長し、衣服がほぼ人体モデルに接する点がダーツの終点となる。このためダーツの終点でパターン４０は人体モデル４２にフィットする。 The dart design will be described with reference to FIGS. Design clothes and simulate the state of wearing a human body model in three dimensions. For example, reference numeral 40 in FIG. 3 denotes a clothing pattern, where the pattern means pattern data or pattern paper, and the data processing means pattern data. Reference numeral 42 denotes a human body model. FIG. 3A) shows the wearing state in a side view and B) in a front view. Also, ● indicates the position (base point) of the dart. The dart is extended from this position in the direction of the arrow in the figure, and the end point of the dart is the point at which the clothes are in contact with the human body model. For this reason, the pattern 40 fits the human body model 42 at the end point of the dart.
　ダーツの幅は図４～図６のようにして決定する。以下添え字iはダーツの番号を示し、Ｌiは衣服の内周から人体モデルの表面までの距離を表し、人体モデルや衣服は左右対称とするので、左右対称な２つのダーツは、衣服から人体モデルまでの距離が等しい。さらに人体モデルの中心をＡ，衣服の中心をＢとし、これらが左右方向にずれている場合、着装シミュレーションに問題があるものとして、左右方向の中心位置を一致させる。また図４の下側が前面を、上側が背面を示す。 The width of the dart is determined as shown in FIGS. In the following, the subscript i indicates the dart number, and Li indicates the distance from the inner circumference of the garment to the surface of the human body model. Since the human body model and the garment are symmetrical, The distance to the model is equal. Furthermore, when the center of the human body model is A and the center of the clothes is B, and these are shifted in the left-right direction, the center positions in the left-right direction are made to coincide with each other, assuming that there is a problem with the wearing simulation. Also, the lower side of FIG. 4 shows the front side, and the upper side shows the back side.
　ウェストなどの位置で、人体モデルの周長は既知で、衣服の内周の周長もパターンデータ、あるいは３Ｄシミュレーションデータから求まる。そしてこれらの差から、衣服を着装するために必要なゆとりｄを引き、これをダーツに分配する。例えば周長の差をＳ、衣服と人体モデルとの距離をＬi、周長に必要なゆとりをｄ、人体モデルと衣服との距離に必要なゆとりをｆとすると、ｉ番目のダーツの幅Ｗiは、
　Ｗi＝(Ｓ－ｄ)×(Ｌi－ｆ)÷Σｉ(Ｌi－ｆ)　となる。 At positions such as the waist, the circumference of the human body model is known, and the circumference of the inner circumference of the clothes can also be obtained from pattern data or 3D simulation data. Then, from these differences, a clearance d necessary for wearing the clothes is subtracted and distributed to the darts. For example, if the circumference difference is S, the distance between the clothes and the human body model is Li, the clearance required for the circumference is d, and the clearance necessary for the distance between the human body model and the clothes is f, the width Wi of the i-th dart. Is
Wi = (S−d) × (Li−f) ÷ Σ i (Li−f).
　次に人体モデルの軸方向に沿って、図３の場合ウェストからヒップへ向けて、ダーツを延長し、途中の複数の位置で距離Ｌiがどのように変化するかを求める。この状況を図５，図６に示し、パターン４０のやや内側の一点鎖線はゆとり分の隙間を示す。そして求めたＬiに応じてダーツの幅を変化させると、図５のような曲線的なダーツ、あるいは図６のような直線的なダーツが得られる。 Next, along the axial direction of the human body model, the dart is extended from the waist to the hip in the case of FIG. 3, and how the distance Li changes at a plurality of positions in the middle is obtained. This situation is shown in FIG. 5 and FIG. 6, and the one-dot chain line slightly inside the pattern 40 indicates a clearance for the clearance. When the width of the dart is changed according to the obtained Li, a curved dart as shown in FIG. 5 or a linear dart as shown in FIG. 6 is obtained.
　これらの処理は左右対称な複数のダーツの半数について実行すれば良く、残る半数にはダーツの配置と形状をコピーすればよい。図７にこの状況を示し、例えばパターン４０の左右半身に対して３箇所のダーツ形成位置Ｐ1～Ｐ3を指定し、これに応じて人体モデルとの距離Ｌ1～Ｌ3と、周長の差Ｓの１／２のＳ／２を求め、残る半身に対してダーツ形成位置Ｐ1'～Ｐ3'を求め、ダーツの幅Ｌ1～Ｌ3は左右対称とすればよい。 These processes may be executed for half of the symmetrical darts, and the dart arrangement and shape may be copied to the remaining half. FIG. 7 shows this situation. For example, three dart formation positions P1 to P3 are designated for the left and right half of the pattern 40, and the distances L1 to L3 from the human body model and the circumference difference S are specified accordingly. The S / 2 of 1/2 is obtained, the dart formation positions P1 ′ to P3 ′ are obtained for the remaining half body, and the widths L1 to L3 of the darts may be symmetrical.
　図８～図１１にダーツのデザイン例を示す。図８は人体モデルと周囲のパターンペーパー（ダーツ形成前）を示し、図の右側は人体モデル(細線)とパターン(太線)をウェストでの水平断面で示している。また図９はヒップの位置での人体モデルとパターンペーパーの断面を示している。そして例えば図８の右上の、人体モデルと周囲のパターンの断面表示で、左右半身に対しダーツの形成位置をマウスなどで指定する。断面表示から指定する代わりに、側面視や正面視、あるいは背面視などから、例えば人体モデルとパターンをゆっくり回転させながら、ダーツの位置を指定しても良い。しかしながら断面から入力すると、より正確にダーツの位置を入力できる。 8 to 11 show examples of dart designs. FIG. 8 shows a human body model and surrounding pattern paper (before dart formation), and the right side of the figure shows a human body model (thin line) and a pattern (thick line) in a horizontal section at the waist. FIG. 9 shows a cross section of the human body model and the pattern paper at the hip position. Then, for example, in a cross-sectional display of the human body model and surrounding patterns at the upper right in FIG. Instead of specifying from the cross-sectional display, the position of the dart may be specified from the side view, front view, back view, etc. while slowly rotating the human body model and the pattern, for example. However, if the cross section is entered, the dart position can be entered more accurately.
　ダーツの位置は衣服の１周分入力しても良いが、好ましくは左右半身分入力すればよい。ダーツを設ける位置にはある程度の経験則があるので、例えばダーツの個数のみを入力し、これを経験則に従って例えばウェストの周囲に配置しても良い。ダーツを自動的に配置する場合、パターンは通常は前後に２分されているので、前後のパターンの境界に縫い代が必要で、この部分にもダーツを設ける。そしてこれ以外のダーツを、前後の適宜の位置に経験則に従って配置する。 The dart position may be input for one lap of clothes, but preferably the left and right half of the body is input. Since there is a certain amount of empirical rule at the position where the dart is provided, for example, only the number of darts may be input and arranged according to the empirical rule, for example, around the waist. When the darts are automatically arranged, the pattern is usually divided into two parts in the front and back, so a sewing allowance is required at the boundary between the front and back patterns, and a dart is also provided in this part. Then, other darts are arranged according to empirical rules at appropriate positions before and after.
　図１０は実施例のようにしてダーツを形成したパターンペーパーの着装状態を示し、図の右側にウェスト位置でのパターンペーパーと人体モデルの断面を示す。図１０でウェストから下向きにパターンペーパー上を走る線はダーツを表す。 FIG. 10 shows the wearing state of the pattern paper on which the dart is formed as in the embodiment, and the cross section of the pattern paper and the human body model at the waist position is shown on the right side of the figure. In FIG. 10, the line running on the pattern paper from the waist downward represents the dart.
　図１１はダーツ作成前のパターンと、ダーツ作成後のパターンを示し、スカートの前側(図の右側)と後側(左側)とを示している。５１～５５，５１'～５５'は通常のダーツで、これらのダーツは左右対称に配置され、５６，５６'は縫い合わせ位置のダーツである。 FIG. 11 shows the pattern before dart creation and the pattern after dart creation, and shows the front side (right side of the figure) and the back side (left side) of the skirt. Reference numerals 51 to 55 and 51 ′ to 55 ′ are normal darts. These darts are arranged symmetrically, and 56 and 56 ′ are darts at the sewing position.
　ダーツはスカートに限らずジャケット、ワンピース、その他種々の衣類に対し適用でき、婦人服に限らず、子供服や紳士服にも適用できる。またスカートの種類は任意である。図１２の６０～６６はパーツの例で、パーツ６０は前身頃、パーツ６１は後身頃であり、パーツ６２は前身頃の左右半身である。またパーツ６４はスカートの前半分の左右半身で、パーツ６６はスカートの半身６４の上側に縫製するパーツである。７０～７６はダーツで、ダーツ７０，７１，７３ではウェストの位置から上下両側にダーツが細くなっている。このため図の横線で示したウェストの位置から上下両側にダーツを延長し、ダーツの形状を決定する。ダーツ７２は胸の部分で、パーツ６２を立体的に膨らませるためのダーツである。ダーツ７４，７６では、ダーツ７４の上端とダーツ７６の下端とが重なるように、パーツ６６，６４が縫合される。 Darts can be applied not only to skirts, but also to jackets, dresses, and other various clothing, not only women's clothing, but also children's clothing and men's clothing. The type of skirt is arbitrary. In FIG. 12, 60 to 66 are examples of parts, where part 60 is the front body, part 61 is the back body, and part 62 is the left and right half of the front body. The part 64 is the left and right half of the front half of the skirt, and the part 66 is a part that is sewn on the upper side of the half of the skirt 64. Reference numerals 70 to 76 are darts. In the darts 70, 71 and 73, the darts are narrowed on both the upper and lower sides from the waist position. For this reason, the dart is extended from the waist position indicated by the horizontal line in the figure to the upper and lower sides to determine the shape of the dart. The dart 72 is a dart for inflating the part 62 three-dimensionally at the chest. In the darts 74 and 76, the parts 66 and 64 are sewn so that the upper end of the dart 74 and the lower end of the dart 76 overlap.
　ダーツ７２のように、立体的な膨らみを設けるためのダーツ形状の決定を図１３に示す。バストトップの位置が既知なので、そこから衣服の左右の端までの距離ｒが求まる。ダーツ７２により、バストトップを中心に衣服が盛り上がり、ダーツ７２による切り込み角θが大きいほどｈは大きくなる。盛り上がるべき高さをｈとし、ダーツの切り込み角θをラジアン単位で表す。バストトップの周囲で衣服が円錐状を成すものとすると、円錐の頂点から周囲までの距離はｒで、高さはｈであり、円錐の底面の周長はｒ×(２π－θ)となる。従って円錐の底面での半径Ｒは　Ｒ＝ｒ・(１－θ／２π)　で、ピタゴラスの定理から、
　ｈ＝(ｒ２－Ｒ２)１／２＝ｒ(θ／π)1/2(１－θ／４π)1/2≒ｒ(θ／π)1/2(１－θ／(８π))
となる。そこでｈとｒとからθが求まり、ダーツの幅が定まる。他の点では図１～図１１の実施例と同様で、ダーツ７２は例えば左右対称である。 FIG. 13 shows the determination of the dart shape for providing a three-dimensional bulge like the dart 72. Since the position of the bust top is known, the distance r from there to the left and right ends of the clothes is obtained. The dart 72 swells around the bust top, and h increases as the cutting angle θ by the dart 72 increases. The height to be raised is h, and the dart cutting angle θ is expressed in radians. If the garment has a conical shape around the bust top, the distance from the apex of the cone to the circumference is r, the height is h, and the circumference of the bottom of the cone is r × (2π−θ). . Therefore, the radius R at the bottom of the cone is R = r · (1−θ / 2π). From Pythagorean theorem,
h = (r 2 −R 2 ) 1/2 = r (θ / π) 1/2 (1-θ / 4π) 1/2 ≈r (θ / π) 1/2 (1-θ / (8π) )
It becomes. Therefore, θ is obtained from h and r, and the width of the dart is determined. The other points are the same as those of the embodiment of FIGS. 1 to 11, and the dart 72 is, for example, symmetrical.
　実施例では以下の効果が得られる。
(1)　ダーツの形成位置を入力するだけで、自動的にダーツのデザインができる。
(2)　ダーツの幅や長さも、衣服が人体モデルにフィットするように自動的に求めることができる。
(3)　ダーツの終点は衣服が人体モデルにほぼフィットする位置となる。

(4) Since the distance between the clothes and the human body model is obtained at each part on the extension line of the dart, the clothes and the human body model fit not only at the starting point and the ending point but also at each halfway position.
　実施例では、３Ｄシミュレーションで、衣服のどの位置が人体モデルのどの位置に対応するかを求め、衣服の周長自体は求めた位置に沿ってパターンデータから求める。また衣服と人体モデルとの距離は３Ｄシミュレーションから求める。しかし３Ｄシミュレーションにより変形した衣服の周長を求めても良い。 In the embodiment, in 3D simulation, which position of the clothing corresponds to which position of the human body model is obtained, and the circumference of the clothing itself is obtained from the pattern data along the obtained position. The distance between the clothes and the human body model is obtained from a 3D simulation. However, you may obtain | require the circumference of the clothes which deform | transformed by 3D simulation.
