1) visibility factor
可见因子
1.
Also,a visibility factor is introduced to calculate the percentage of light seen by a single pixel in the scene and some other solutions are proposed to accelerate the efficiency of rendering,such as fragment shader with GPU,a Hierarchical Shadow Map(HSM),adaptive precision,and so on.
算法对每个光源都产生对应的阴影图,使用阴影图作为对场景的离散化表示,引入可见因子来计算场景点的亮度信息,并采用GPU片元着色、层次阴影图、自适应精度等方法加速阴影渲染。
2) visibility factor
可见性因子
3) isotropic sky view factor
各向同性可见因子
1.
The terrain factors (slope grade,slope aspect,shade,isotropic sky view factor) were calculated using the domestic and overseas estimating methods of solar radiation and digital elevation model (DEM) so that the more precise model than existing eodels was derived.
借鉴国内外计算坡地太阳辐射的方法,利用数字高程模型(DEM)生成了计算山地太阳辐射的地形因子(坡度、坡向、遮蔽度、各向同性可见因子),比现有的模型更准确地计算了晴空下山地太阳总辐射、直接辐射、散射辐射和周围地形的反射辐射,在此基础上分析了坡度、坡向对太阳辐射的影响。
4) visible subsegment
可见子段
1.
By using geometry calculation, a more concise and effective method is presented to obtain the eigenvalues of the intersection point of polygon and arris, and by using data structure of stack in program, a sorting solution to visible subsegments can be realized.
利用几何计算对多边形与棱之间的交点特征值的求取给出了更简洁有效的方法,并在程序中利用堆栈数据结构实现可见子段的求解与归并。
5) visible component
可见子星
6) light photon
可见光子
