| 摘 要： | 依据光线跟踪算法和纹理映射技术,提出了一个利用光线微分计算光线密度的方法,即在进行光线跟踪的同时,进行跟踪光线微分。实践结果证明,把求得的光线微分应用于纹理映射技术中可加速绘制速度,并有适用面广、易于实现的特点。

| Abstract: | By the study for rays tracing algorithm and texture mapping technology, we provide a novel approach for quickly and robustly tracking an approximation to a ray footprint based on ray differentials. When we track the rays, we can track the ray differentials. Then the differentials can be applied in mipmapping algorithm. It accelerates the velocity of rending large. The method is practical and is Characterized by its broad applicability and easy realization. |
