【摘要】 结合基于场景图构建的虚拟场景和仿真应用的特点,提出了一种基于视域剔除和图像缓存技术的复杂场景快速绘制方法。此方法能够有效地解决图像缓存算法中,由于未考虑视域不可见剔除,而造成的绘制元素复杂度计算偏差引起图像缓存误判断,从而降低绘制效率的问题。另外,通过对图像缓存有效性的判断,可以简化视域不可见剔除的判断,提高绘制效率。更多还原

【Abstract】 Combining the feature of virtual scene and emulate application based on the scene graph, a new fast rendering approach was proposed based on view frustum culling algorithm and image caching algorithm. This new approach can not only resolve the problem of low rendering efficiency caused by compute inaccuracy of rendering element’s complexity in image caching algorithm, but also can predigest view frustum invisible culling by judging the validity of image caching, and consequently improve rendering efficiency.更多还原
