Method and apparatus for 3D clothing draping simulation
When producing a piece of three-dimensional (3D) clothing through a computer simulation, a 3D clothing draping simulation method includes inputting a two-dimensional (2D) clothing pattern, inputting a pattern block, matching the input 2D clothing pattern to the input pattern block, converting the matched 2D clothing pattern and pattern block into a database (DB), selecting a pattern block which is matched with 2D clothing pattern from the pattern block database, and automatically sewing 2D clothing patterns matched with selected pattern blocks together according to sewing information of the pattern blocks.
1. A three-dimensional (3D) clothing draping simulation method comprising draping two-dimensional (2D) clothing patterns on an avatar model and rendering and displaying a result of the draping, the method comprising:
selecting pattern blocks from a pattern block database (DB) storing predefined pattern blocks, respective predefined pattern blocks being matched to corresponding 2D clothing patterns; and
automatically sewing 2D clothing patterns matched with the selected pattern blocks together according to sewing information of the selected pattern blocks,
wherein each of the predefined pattern blocks comprises edges respectively corresponding to sewing units of the corresponding 2D clothing patterns, and
wherein automatic sewing information about the sewing units of the 2D clothing patterns is set at corresponding edges of the predefined pattern blocks.
2. The method of claim 1 , further comprising:
inputting 2D clothing patterns respectively forming a piece of clothing;
inputting pattern blocks respectively comprising sewing information about corresponding 2D clothing patterns;
matching the input 2D clothing patterns to the input pattern blocks; and
converting the matched 2D clothing patterns and pattern blocks into the pattern block database (DB),
wherein the matching of the input 2D clothing patterns to the input pattern blocks comprises automatically matching the input 2D clothing patterns to the pattern blocks by analyzing a shape of the input 2D clothing patterns.
3. The method of claim 2 , wherein the matching of the input 2D clothing patterns to the input pattern blocks further comprises:
verifying whether a 2D clothing pattern matched with a pattern block is a pattern corresponding to the pattern block.
4. The method of claim 2 , wherein the inputting of 2D clothing patterns further comprises:
selecting a clothing template that is a group of the 2D clothing patterns forming a piece of 3clothing.
5. The method of claim 1 , further comprising:
before the automatic sewing, comparing lengths of borders of the 2D clothing patterns to be connected with each other; and
automatically grading sizes of the 2D clothing patterns to change the length of the borders of the 2D clothing patterns to be the same.
