摘　　要：现有的纹理映射技术由于物体几何形状多变,难以给出一般表达式,以至于限制了纹理映射技术的应用,针对这一问题,研究适用于不规则多边形和参数曲面的纹理映射Catmull算法及Blinn算法。同时,在OpenGL中利用样条曲线的方式,通过两步纹理映射技术和环境纹理映射技术实现了平面与参数曲面的纹理映射贴图。结果表明,研究内容对于纹理映射技术的推广及应用均具有重要意义。It is difficult for the current texture mapping technology to give the general expression due to the changeable geometrical shapes of the object,resulting in application limitations of the texture mapping technology.Therefore,the Catmull algorithm and Blinn algorithm applicable for irregular polygon and parametric curved surface texture mapping are studied.The two-step texture mapping technology and environmental texture mapping technology are adopted to realize plane and parametric curved surface texture mapping by using the spline curve mode in OpenGL.The results show that the research content in this pa-per has great significance for promotion and application of the texture mapping technology.
