Embodiment Construction

[0017] refer to figure 1 , represents a system frame diagram based on the present invention. In the process of importing the model, the 2D garment model is converted into a 3D garment format, so that it can be processed uniformly in the subsequent process.

[0018] figure 2 Flow simulated for clothes. Include the following steps:

[0019] 1) Placing the virtual human: Placing the virtual human in a suitable position will save a lot of computing time for the computer.

[0020] 2) Clothes making: With the pose of the avatar as a guide, draw some curves to form panels, which are equivalent to the cut pieces of the clothes, and then sew these two-dimensional panels at the desired positions.

[0021] 3) Dressing the virtual person: This step will intuitively show the effect of the clothing on the virtual person's previous actions. First, set the virtual human as the conflict object of the clothes, and add the cloth solver to the clothes, then use constraints and dynamic field...

Abstract

The invention discloses a three-dimensional dressing showing and editing method based on CAD garment pieces. In the three-dimensional dressing showing and editing method, a three-dimensional mannequin and two-dimensional CAD garment pieces are taken as the input, and a system directly generates script files of general three-dimensional modeling software such as Maya after the operations on the garment pieces such as seaming, locating, etc. The script files can obtain a three-dimensional garment cloth simulation result after leading in the general three-dimensional modeling software, and form the true feelings that the garment pieces are put on a human body after seaming.

Description

technical field [0001] The invention relates to the technical field of two-dimensional and three-dimensional graphic data processing, in particular to a three-dimensional clothing display and editing method based on CAD clothing pieces. Background technique [0002] Computer-aided three-dimensional clothing display and editing technology is a design tool and method that has a profound impact on clothing designers. Although the 3D clothing CAD system has been gradually applied, due to the complexity of the human body, clothing and fabric models, the existing 3D clothing CAD system technology still has deficiencies such as high price, poor sense of reality, and inconvenient use. Therefore, how to develop a more realistic, accurate, and easy-to-interact 3D clothing demonstration system has high research and economic value. [0003] At present, the relevant patents related to the three-dimensional clothing demonstration and editing system include: a method for designing three-d...
