摘　　要：当使用单幅图像对曲面体表面进行颜色纹理映射时,需要根据曲面体的参数方程反求顶点的纹理坐标,求解过程依赖于具体的曲面体方程,计算过程复杂,针对这个问题,本文提出了一种统一纹理映射方法,使得在划分曲面体的网格顶点时就直接计算了纹理坐标,计算公式统一,便于绘制颜色纹理与凹凸纹理.Drawing curved surface commonly use parametric equation to calculate texture coordinates. This method not only depend on specific equation but also need complex calculation. A unified texture mapping method was put forward in this paper. Dividing mesh and texture coordinates were calculated at the same time. This method has uniunified expression,is easy to paint color texture and bump texture.
