1.在把显示对象的每个面上每一点的颜色值填入帧缓冲器相应单元前,要把这点的深度值和Z-buffer中相应单元的值进行比较。 2.只有前者小于后者时才改变帧缓冲器的那一单元的值,同时Z-buffer中相应单元的值也要改成这点的深度值;否则帧缓冲器相应单元的值不变。 八、Z-buffer Method 上面的图按顺序自己领悟一下...
OpenGL,或者D3D 的深度缓存都存在精度问题,在最新的Nvidia GF8 系列显卡中已经开始应用float point depth buffer. 而在此之间,深度缓存其实只有位平面的概念. 这随API的不同,都需要指定后缓存深度缓存精度, Depth ,我一般使用24位,也就是D3D中常见的 D24S8. 但除非你是用浮点,否则都会有精度损失的问题,这种情况...
...的游戏卡来说 在抗锯齿(antialiasing)深度缓冲(zbuffer) 双面光照(2side) GI(全域光照)上比一般游戏卡有更好的表现能力。 5i01.com|基于32个网页 2. 深度缓存 ...的环节,在三维CAD产品中一般使用的两种渲染方法:深度缓存(zbuffer)和光线跟踪(raytrac-ing)。
Next the compressed Z-values are transferred to a Z-buffer. This saves memory space because only 2 full values (MAX and MIN) have to be stored, and the remaining h indices can be stored using smaller numbers of bits because there are only a finite, small number of intervals. To ...
这个图要怎么看呢,首先看到左图,其中横轴是z_{ndc},因为我们之前选择了int8作为buffer格式,所以可以看到红点在横轴上是均匀分布的;纵轴则代表了红点在View Space下的对应平面距离。 右图则是更直观地统计View Space下各区间的点数的柱形图,其中横轴为View Space下的距离,每一个柱形反映了View Space的一段距离区...
深度缓存ZBuffer线性化 doublelinearizeDepth(doublenearz,doublefarz,doubledepth) { depth=2.0* depth -1.0;return(2.0* nearz) / (farz + nearz - depth * (farz -nearz)); }
In the case where the first object is in front of a later object, the later object does not get rendered/blended, because the Z-Buffer was marked to ignore everything behind the first one. Camera -> 1 2 解决思路: 动态调整Z轴,因为Z是根据你添加Model3D顺序决定的,所以每次调整角度的时候动...
