一种基于手绘的自由形体建模方法研究

提出了一种基于手绘的自由形体建模方法。通过平滑去噪、重采样、曲线拟合等操作，将输入的手绘笔画转化为均匀间隔的点序列，根据提取到的几何信息生成三维网格模型，并通过对模型进行光照渲染和纹理贴图完成具有特定形状的自由形体的绘制。实验结果表明，该方法能够简单快速地实现符合用户输入意图的三维形体建模。

Research on Free Modeling Method Based on Free Hand Sketching

A method of free modeling based on free hand sketching was proposed.Through the operations including smooth denoising, resampling, curve fitting, the sketch strokes obtained from users were transformed into sequence of evenly spaced points, from which the geometric information of target model was extracted. According to the geometric information, three-dimensional mesh model was generated. The drawing of free body with particular shape can be completed after adding texture mapping and illumination rendering to the 3d mesh model. Experimental results show that the method can be easy and quick to achieve threcdimensional shape modeling in line with users's ketching intention.
