针对舰船设计中模型构建质量较差、视觉呈现效果不理想等问题，研究基于虚拟现实技术的舰船三维模型设计方法。利用Bézier曲面和B样条曲面设计精确、复杂的A级曲面模型，赋予A级曲面模型不同的材质和色彩，使用A级曲面模型构建舰船船体、上层建筑、机械设备等的三维结构，采用无缝纹理映射方法将标定的舰船纹理图像映射至舰船三维模型，将设计元素和分析结果进行整合，并在虚拟现实环境中进行验证，完成舰船三维模型设计。实验结果显示，该方法所设计模型与最初的概念草图一致度高，模型分辨率达到2200 ppi以上；纹理映射分析的各项指标均在95%以上，呈现出更好的视觉效果。
Research on a 3D ship model design method based on virtual reality technology to address issues such as poor model construction quality and unsatisfactory visual presentation effects in ship design. Design precise and complex A-level surface models using Bézier surfaces and B-spline surfaces, assign different materials and colors to the A-level surface models, use the A-level surface models to construct three-dimensional structures of ship hulls, superstructures, mechanical equipment, etc., use seamless texture mapping methods to map the calibrated ship texture images to the ship three-dimensional model, integrate design elements and analysis results, and verify them in a virtual reality environment to complete the ship three-dimensional model design. The experimental results show that the model designed by this method has the highest consistency with the initial concept sketch, with a model resolution of over 2200 ppi, the various indicators of texture mapping analysis are all above 95%, presenting better visual effects.
