Abstract

The invention discloses a three-dimensional visualization method to process the thermal comfort of clothing. A human body-clothing thermal comfort model which is based on two nodes and multiple nodes adopts three-dimensional true human body and clothing surface mapping, mesh segmentation and cutting to constitute a true human body and clothing geometric model; a human body thermal regulation simulation model which is based on a three-dimensional finite element adopts unit surface mapping and cutting algorithm to constitute the true human body and clothing geometric model, so as to realize visualized display of a virtual reality environment. The invention is designed against the model in the visualization requirement of the human body-clothing thermal and moisture simulation, the invention realizes the visualized display of the virtual reality environment of the human body-clothing thermal and moisture transfer process and the clothing comfort by the implementation of the visualization treatment of the invention, so as to facilitate the realization of system integration and virtual reality application, and consequently obtain good visualization effect of the clothing thermal comfort simulation.

Description

technical field [0001] The invention relates to the technical field of functional clothing CAD in the field of computer simulation research, in particular to a method for realizing visualization of clothing thermal comfort in functional clothing design. Background technique [0002] In functional clothing design, the result of computer simulation calculation is multi-dimensional time series data, and the amount of data generated by numerical calculation is also very large. Without visualization, it is difficult to understand the data accurately and effectively only relying on statistical analysis methods such as charts. For the study of clothing thermal comfort, visualization is of great significance. Visualization can realize the virtual display of the thermal comfort performance of clothing in the virtual dressing scene. This is of great significance for helping researchers better understand data, conduct model analysis and control the simulation calculation process, as ...
