An alternative is not to attempt to build increasingly more complex models , but rather to build a simple model and to add detail as part of the rendering process 一个可替代的方案是,与其尝试建立越来越复杂的模型,不如建好一个简单的模型,然后在渲染过程成逐渐加入细节。
Gpus graphics processing units are used to compute virtual vertices quickly and further accelerate the computing and rendering processes . as a result , realistic effects of reflections and refractions on implicit surfaces are rendered in real time 本文主要结合隐式曲面的特点,总结了方程定义隐式曲面反射折射虚顶点的计算方法,并特别针对旋转曲面,提出了简单实用的虚顶点计算方法。
The generation and render process of the tree could be simplified to : draw the branches from the root , then the branches are split into left branch and right branch . the process of drawing branch would be divided into many steps , we can draw the leaves in the last step 该模型中树木的生成与绘制过程可简化为:从根向上画树枝,分为左分枝和右分枝,画树枝的过程可分为若干层,最后一层画树叶。
2 , study ing and perfect ing the algorithms of walkthrough in virtual environment , accelerating the walkthrough in virtual environment in this paper , we evaluate the advantage and disadvantage of the current algorithms of walkthrough in virtual environment by the rendering process of photorealistic graphics , and then brought forward a new algorithms of real time walkthrough based on the integrated polygon and texture 2 、研究并改进虚拟环境漫游算法,加速虚拟环境的漫游本文通过真实感图形的绘制流程米评价目前虚拟环境漫游常用算法的优劣,提出了相对较新的一种基于几何和图像混合简化方法的实时漫游算法。
